I’m an old diamond blade guy from the concrete cutting world. The another way to quickly sharpen a glazed blade is to cut into an Carborundum wheel. This is how we “dress” new blades at the factory. Don’t over dress it, because you will waste diamonds. You want the stones to just be exposed.

Thank you man. I was cutting like 60 meters of pretty hard 2 cm ceramic tiles and after 2 hours, the diamond blade was done. Now it cuts maybe better than new one. 👍

I subscribed. Loved the content here as I have blades I need to do this with. I love cutting rocks. I started out cutting core in a core shack and had a couple saws. The core shack took a hit with a boulder the size of a garbage can and took out the whole corner. We were too close to the blast and the blast man was saying face the blast and dodge the rocks. HaHa. Later on had a core shack there with hired cutters and 4 saws as I was then project geologist and had a drill program going on. We drilled all winter to delineate the ore body and then in the summer started production using a heap leach process. I loved going up to the smelter and looking at the gold when they were doing a pour. The news came and took a photo of me one time holding a gold bar for the news paper. I was only 25 years old back then fresh out of university. I didn't have anyone telling me what to do. I just made it up as I went along. Making mylar draftings of the ore body using the drill hole data and the returning assay results every day. The drillers gave me a bottle of whiskey as a gift and I don't drink so I saved it. One night I broke it open and drank it with some friends and went to this bar where my friends from work had a band. I was up dancing and I don't dance. That was a fun night! One of the drillers whom I became close friends with died a few years back on Christmas eve. He was a gambling addict and I watched him and it was no different than being a coke head as he suffered great depression because of it and smoked like a chimney. I nicknamed him Rockin to make him feel proud. Rockin Randy Petland. He was a star goalie in soccer RIP. One night at work his father's fingers went missing. Blood in the snow.

I needed this video so bad thanks so much Jared I have blades I don't wanna throw away yet.

Yes, the blades seem to last forever. Great content, thanks. John

Did this and it worked awesome! Thank you so much for your research into this. Much appreciated. This was incredibly informative.

Thank you for showing this. I watched a video by another guy that said he was going to show how to sharpen the blades. He showed the file, then off-camera there was a bunch of banging. When he came back one he said that's how you do it. The video was worthless.

I love it when you nerd out LOL I want to thank James too for giving you that microscope. I have totally been enjoying seeing all the cool photos that you've been able to get with it it's fascinating. This one hopefully will save people a lot of money.

I still have my old blades kicking around, after watching this video I'm very intrigued to test your method. If this in fact works for me, and in the long run saves me cash on blades, you will have earned my contribution to this channel. The science you provide, and the money saving experiments you show, truly need to be supported. I encourage anyone who has watched currently rockhounding videos and have saved money to definitely contribute to the cause. Thanks Jared!

I knew you would find some cool uses for the microscope. Really good explanation on the blades. I hope my friends miss this episode because I have been getting their old blades for years, even though I have explained it to them, they would rather buy a new one than sharpen the old one. Good for me. 😊Be happy, safe and stay healthy. 😷⚒

I've watched numerous videos on sharpening diamond blades. By far I've learned so much more on your channel. Well done Jared! Thank you! I have 5 cats and saw your sign "no cats" lol

I just used my 10” for the first time today. Thanks so much for explaining all about the blades and their upkeep. I knew nothing about them before and had no idea how long they lasted.

Thanks I m getting ready to rebuild my grandfathers saw and was going to buy a new blade

Between the “making your own diamond wheel belts” video and this video on how to save your dull diamond saw blades, I’m a subscriber for sure. Such great info and pictures for dummies like me lol. Thank you again bud, you’re awesome

This was awesome! I didn’t know that the diamond blade could be sharpened and I wondered how the notch blade worked because I really couldn’t see diamond, but you just explained both, thank you😊❤️

Huh, interesting! Love seeing the microscope views👍👍 In another life we used MK Diamond 60 grit dressing stones on tile saws as instructed by my boss at the time. I didn't actually cut tile but he swore by them...and knew his stuff! That might be worth a test if you feel like trying different methods in the future. All you did was "cut" the dressing stone slightly to refresh the blade. If the method holds up under a microscope it could be a small dollar investment resulting in saved time....and another interesting use of the microscope and corresponding video. Totally random, that boss used to take the spent 14" concrete / asphalt blades and hang them for plinking.

Thank you so much for this. I am about start cutting rocks for the first time so this will help me maintain my blade a lot.

great video, TOP NOTCH.

Really Cool! Thank you.

I just bought two new blades yesterday! I think today I'm going to try to rejuvenate my old blades thanks!

Thank you kind Sir.

You could not have posted this at a better time, I just bought a very expensive diamond blade, hopefully doing this will help it last for a long time!

Thank you so much Jared because I just used your method for sharpening dull blades with the bastard file. It worked really well. I can now keep on cutting rocks without having to buy a new blade for a while.

I am sooo glad I haven't thrown away my old blades! I'm using a tile saw but the blades are similar in construction so I gave your trick a whirl! I'll be cutting rocks with one of my older saw blades this morning. I can definitely feel the difference in the edge on 3 blades that were almost tossed!!! Thank you!

Great help! thank you so much

Great video. Thank You.

I look at your videos from Iraq and it is very informative and not published online so easy and clear, thank you bro👏👏👍👍👍👍 I will continue to see your vids🎊

Never thought of that. Great way to use your new tool, also gonna make old tile saw blades better for work. Thanks man, great ideas and content all the time.

Jared you’re a rockstar and everyone in the rockhounding community attest to this. I too would be curious about the 180 grit flat lap

Good tips! I wouldn't have thought a little tapping could ruin the arbor, but I guess it wouldn't take much misalignment to throw everything in a tizzy. Another factor in the life of a blade is the kerf of the cut. If the diamondiferous area narrows to no more than the width of the rest of the blade, then the rock will rub against the steel of the blade leading to heating and binding. The chop file method works on sintered blade faces as well, but does not refresh the diamonds on the sides. Refreshing those with a bit of filing/dressing will keep your cut faces nice and smooth and reduce the amount of time you need to spend polishing later.

Yes dude! Nice lapidary sciencing! I watched the brick one all the way through because someone suggested it to me but I had to watch this one first. This is big brain blade saving. Really informative too. Jumpin back to the brick one and then the one suggested to me about the dressing rod thing 🤘

Great information, sketches and microscopy!

Thanks for the video. It's not even Saturday on "The Channel where we look at EVERYTHING Rockhounding related". More great content!

What a wonderful video! Thank you so much!

Very good information! Thank you Jared!

I was like, What! I can sharpen those! Great topic

nagyon hasznos video, koszonom szepen !

Awesome videos…excellent explanations on all 3 videos

Thanks Jared, this kind of information clearly sets you apart from other channels out there. You ROCK (pun intended)!

Great info!!! 👍

Hi Jarred, like most people starting out in this hobby I assumed that once these blades started to dull that that was the end of the blade. I took the time to read all the other comments so far and there is also some interesting views in the comments. Like most people I have heard of using a brick to clean the blade on your saw and as yet have not tried this, though I can understand it could have some merit. Thank you for the video on this subject, it is great to see that we can save dollars on the consumable portion of the hobby as some of these blades are expensive items. (There’s another video for you cheaper type blades verses some expensive ones, is there are difference in cutting & life span) Another good video and subject with some actual information & visuals behind it. 👍. Keep Safe & Keep Rockin

Thanks for the great explanation of the notched blade. Now I've got to go do that to a bunch of my trim blades and try them again!!

Dude this is amazing!!!😎 Thank you so much for going in depth about this topic. I so badly needed this😄

Thumbs Up!! Jared, Greetings from Guadalajara, Mexico. I just enjoyed to see you how you work cutting rocks. Probably I’ll do it some time in the future watching your videos.

Thank you so much for putting this together! Extremely helpful for someone who hasn't had a lot of experience! You saved me $$ :)

Great job, lots of good usable info. Can’t wait for what’s next!

Nice video my friend!!

Thank you so much for this video. Need to know information.

Thank you, you are a excellent teacher, thanks for sharing. 😊

Outstanding Sir! Really appreciate the work you did here! Just purchased our first lap saw... and I thought the blade dull a bit fast! Your explanation makes tons of sense! Well done... and the microscopic pics really helped. Subscribed and liked!! My new favorite channel!

Thanks! Saved me my first two worn blades.

This is the best video on you tube hands down. Presentation could not have been better and the subject matter was just what I needed. I tried this on my blades and it worked so good. I think that they cut better than when they were new. Thank you so much.

Great video bud!!!..I was pitching my old blades like you said until I saw a video made by (you know them bastards),explaining the whole bastard file technique. But your video goes to a whole new level. The microscope details and explanation of the two types of blades is extremely important. I really appreciate the time you took to make this. I have a few old blades out in the garage destined to the the dump, that now will get the "bastard " treatment. Thanks for helping us all operate our saws to there maximum capability. U rock brotha!!

Nice job on this video. Glad you aren't perpetuating the cutting of bricks, grinding wheels and ceramic for lapidary blade sharpening. You did a good job of explaining and showing the science. Sharpening of a sintered blade works the same. I personally never use notched rim blades, they cut slower than sintered blades. When comparing them top down, there is about 4x more diamond in contact with the rock while cutting, sintered vs notched. RR advert, thumbs up!

As always, good info. I need to clean/face my old blades as well.

Thanks for this video! Your channel always seems to teach me something right when I need it! :)

You are definitely the most informative rock hounding channel. Thank you for sharing your knowledge to some of us who mainly learn this skill from YT. When I started I knew nothing about lapidary and no one to ask on how to work the machine. There is still one thing that I’m curious about. What rpm are better for the blades? Specially for quartz material. Thank you.

Thanks for doing the research. Nerding out is great!!!

Thank you so much for doing this video, Jared! Really love the way you "geeked out" using the microscope views as you explained the science behind it. I tried this with my 14" centered slab saw blade and now it's back to cutting like new again. The wife and I very much enjoy watching your channel and we feel as if we're there along with you, Sara and Laika, looking over your shoulder as you trek to another beautiful location to unearth more treasures. Your videos are always very entertaining and informative and please keep up the good work! Stay safe and rock on!! Rob & Di

Being a machinist for over 40 years and using diamond cutting blades for ceramic parts, we go through a ton of blades of all grits. When the blades start to dull we use a dressing grit stone to give life back to the diamond blade. They come in all sizes and grit. Using the grit stone you grind away the bonding to exposé the diamond. You really should not tap or hit the blade because you could damage it, or crack the bond of the diamond to the steel flange holding the diamond And that could lead to a catastrophic event when the diamond pieces come OFF the steel flange and come back at you at a high rate of speed. Here is a copy of print from Amazon. Norton Abrasives Dressing Tool Stick, Grinding Wheel Tool for maximizing Grinding Wheel Performance. We buy these by the box of 300, so they are cheaper. $1 a piece. You might even use a old red brick. Just go slowly when going into the blade using water of course. Hope this helps.

If you found this to be helpful please drop me a thumbs up and consider subscribing. Also this will work on tiles saw blades as well!

This is so helpful! I'm new to cutting material and am still only using a tile saw with lapidary blade, but I welcome all the education to help me improve my process and maintain my tools. Thank you!

Loved this video!

This has been extremely helpful to me since I am just now starting to work with a new 10" saw. Thank you for your informative vid!

Interesting thank you for sharing and education on this topic 💙

Awesome! Thanks!

Great video! Gonna try it this evening

Great info! Thanks!

Hi I make a cut into an old house brick to refresh the edge, works every time

Great video man. Much appreciate the detailed look at the blades and info on how to sharpen. 👍

Fantastic!! I was a bit downhearted because I seemed to be going through blades so quickly - I'm pumped that I know what's going on with them now and what to do to keep them going. This was one of the most beneficial videos I've watched in a very long while. Thanks!!

Bro I don't know if anyone has said this but you are legendary

I was in the dark on blades. Thank you!

🤦‍♀️. I’ve been throwing out my expensive blades for a long time. I feel so foolish now. Thanks so much for the 🎥. This one is definitely priceless!! Stay Crystal 💫

Thank you.

Interesting! I always used an old grinding wheel or brick. Bricks kinda suck it's like your oil will turn red and stay that way. I'll have to try this.

Great to know how to get the most our of these saw blades ! Thank you!

Invaluable, thanks

Very informative video Thanks

Than you!!

Very good video Jared, thanks for bringing this to us!

Thank you so much!! Very excited to try.

Cheers 🍻 love this video. Great info and awesome thought put into all of it. Dude 😎🤘

Cool and informative video Currently Rockhounding. I think the only way to go full science on improved performance would be to use a saw like my B&I with the gravity feed system, cut a rock and time it, then sharpen and cut again and compare. Thank you for showing us.

Fantastic i learned so very much! Your thought process is incredible! Thanks for doing what you do, i really appreciate you sharing your knowledge!

you definitely have the best informative videos out there.... my compliments I have learned a lot!!! THANK YOU

Please show us how you have the Pro-Flow water cooling system hooked up.

Awesome information! Thanks a million for sharing! 👍

Thanks for the tip, I have tossed a lot of blades that from what you showed still had a lot of life. wont do that again.

Thank you so much! You’re a great teacher😁

Thanks for the great info. and the before and after close-ups. Would be great to hear some discussion on blade speeds for the various sizes, maximum speeds, etc., and how it affects cutting different materials. Is there an ideal speed for most hard materials?

First time I saw you, already liked, subscribed. Thank you very much.

Wow!! You just saved me $65!!!! THANKS!!! Todd

Should have shown the cut surface of the stone under the microscope. You had one side of that trimmed off piece that was cut with both blades, sharpened and new. In metal working, a dull blade will tare the metal rather than cutting and you can see the difference on the worked surface.

Another great demonstration of how useful a microscope it. And your videos are a real service for rockhounders in general.

I have been cutting a whole boule of green corundum. This video lets me do the actual cut. I purchased a 10in trim/slab saw and the blade is wide for a 10 in blade. I am using a spring to provide a light pressure to cut the boule. it takes forever. the boule diameter is about 1 and 1/2 inches, and the blade is about 2 mm wide. I found out that corundum is only 5 times softer than diamond itself. but redoing the blade everyday prior to the continued cutting the single 70mm cut of the boule lengthwise. I used to achieve 2 mm per 8 hour period of cutting. Now I achieve 4mm per 8 hour cutting period time. I am getting a 6in blade so that the cutting blade is only 0.020 mm wide or about. (the main problem is that the width of a 10in black is about 2mm, instead of a 0.020 6in gem blade) (I do wonder if I can stick a 6in blade on a 10in blade machine)? I hope to complete the cut cutting 8 hours a day for 8 days. I used to only cut quartz, and that was quickish. there are very few videos of synthetic corundum being cut. and they are only about 10mm width and 20mm wide and even those videos that cut take time. I do the file first, then use a dressing stone to clean up the blade of the excess metal.

I use sintered blades only so I have no experience with the newer blades. Depending on the blade I have always sharpened the blades by either cuttng a piece of cinder block with some blades and Quartzite or hard stone thru once or twice on other blades. If all else fails I use a 4” grinder with a diamond blade and cut notches in the sintered blade every inch around the blade. Basically making the continuous rim segmented but only much shallower. I wouldn’t cut all the way thru the sintered are, don’t need to and might compromise its structural integrity.

Very good video.

Love the video, thought I needed a new blade!
