Just wanted to say thank you for this video. I had to suffer through a lot of garbage to find someone who actually knew what they were talking about and could demonstrate appropriately. I bought a pair of these diamond stones for my sharpmaker because of you. I also am going to change my technique to downstroke/upstroke because of you. Thank you sir.

well neil, i think the world owes you some thanks! i don't ever think i saw anyone use these diamond rods from start to finish like you!vary good job,bravo.

I like my diamond stones so far. They were expensive but at the same time, they work as advertised and I haven't messed them up yet, so thumbs up from me!

Great advice because I think a lot of people don't understand the difference between the ceramic rods or stones if your sharpening on flat stones and how much more aggressive the diamond stones are!

Thank you for not speeding up the video and showing us, what it takes to do a correct job!!! Subscribed...

I bought one of this at a thrift store for a dollar and 50 cents a i tought it was missing parts but everything was toguether so i took it home tried it and its amazing

wow! this is an old video! I enjoyed watching it! I skipped the "diamond rod" step and went to CBN directly. Now I am curious about the difference. Good video!

You should go to the flats and push down when coming to the tip so you don't have to pull off and risk rounding the edge. Just a thought. Great video, thanks

I'm sure that you've already gone through multiple sharpening systems since this video but I recommend the worksharp precision adjust and then for fine tuning I use the edge-pro tapes stuck right onto the ceramic hone and I'm able to get insane edges on most any steel also I love the ukpk I have the s110v, the lc200n an n690, one s30v and two of the bd1n versions one in each shape...

Excellent video, very informative, thanks.

Makes no sense to ignore the safety rods in my opinion. But the up and down technique is what I use. As for re-profile work, I use Lansky and my Spyderco to keep the edge pristine.

Great video. I'm in the process of getting my chefs knives back into shape. What a drag no thanks to my abuse however this is great info and will save me tons of time with your method!

Spyderco has 2 "diamond" type stones; one is actual diamond and the other one is cbn. Both aren't really good with pressure, but cbn will leave much less deep scratches but cuts as fast The sharpmaker is a great system, just takes super long to reprofile That Ti ukpk looks so sweet

I need a sharpener but there so many types and I'm just confused which one to buy. Since this videos which is obviously 7 years ago, what types of sharpeners have you tried and which one would you recommend? Also is this Diamond rods more coarse than Spyderco's Boron Nitride ?

Thank you for the informative video, I didn't know if Spyderco's Diamond Rod will be suited to re-profile Karambits; this vid helped to make a decision and buy them.

I can't agree more. This is not the "knife superstore" $19.95 ceramic rod 'crock stick' sharpener. This is the real deal. There is no way this should work as well as it does. I have a KME and it will probably stay in the box from now on. For the price and the effort and the result, you can't beat this.

I am having a problem with re profiling a knife. When do you know to re-profile your blade. I have a spiderco sharpmaker with the extra fine rods. Most of my knifes i can get sharp using the 40 degree side. Is reprofilng using the 30 degree side starting with the medium, fine, and extra fine rods 20 to 25 strokes and then doing the same thing with the 40 degree side.? Should you do that every time you sharpen your knife? Very confusing! I have a harnds viper knife I bought, and i cannot get it sharp! I tried the 30 degree side with every rod; medium, then fine and then extra fine 20 to 25 strokes. Then i followed it up with the same thing with the 40 degree side and it wont even cut paper! What am i doing wrong! Any help would be appreciated. I do not understand when and then how to get them sharp.

Hey great vid. Been wondering if i should get these and maybe you could help. I have a para2 with a seriously lopsided grind. I sent it off to a pretty well known wetstone sharpner recommended from blade forum asking to even out the bevels and to give me that 30 degree single bevel and he accomplished neither. I've had now 3 people attempt to sharpen this damn knife and nobody can do it right. it comes back sharp but the bevel is still uneven and still so shallow the sharpmaker hits the shoulder on one side even at the other angle on it so i would probably need to remove quite a bit of material if i get these diamond rods. Do you think these things are up to the task with that major of a reprofiling? Also i have a s30v native 2 that's half spyder edge with a chisel grind, so it's flat on one side and the bevel is only on the other. Any advice for sharpening a knife like this?

Great video as always. I was wondering why you chose diamond over cubic boron nitride? I am trying to decide between them and would love to know the reason you chose this over the other.

I managed to get here due to curiosity of the difference between their diamond and cbn stones for the sharpmaker not entirely sure which I want to get...

I think I need these for my dexter russell fillet blades...they need work after that work sharp belt sharpener that really was crap!

I'd love to see a long term review of this. How well do the rods hold up?

2 hours to reprofile an edge ?? That seems super long for the diamond rods

THATS COOL MAN!!

One question I have - when sharpening an s90v knife, would you first use the diamond on each side (pointed side), then the flat side, followed by the white stone pointed side and flat side? I'm a little confused about the proper order. Thanks!

I'm having the same problem !! Having trouble reprofiling my Mannix two XL !! Any help would be greatly appreciated

Curious why you're not checking for a bur with this system.

20 hours? Are you using your feet?

That was a great vid... thank you, sir!

What is the grit on the medium, fine, ultra stones?

yo, i have a cold steel machete to sharpen, i already started with the black and decker sander but i was wondering, will the rods resist it ? i mean the diamond bits.

Do you have to wash them after prolonged use like the white and grey stones require ???

What kind of steel was the knife you were sharpening?

I wonder what do you use lansky crock rods for if you already have Sharpmaker?

20 hours? Dude.....

So the angle of the Spyderco sharpmaker is 40 degrees inclusive, 20 degrees per side, or 30 degrees inclusive, 15 degrees per side, but their knives come with an 18 degree angle? Makes no sense.

either you have a microphone by your rods or you are using entirely too much force and I cannot imagine you having those diamond rods last unless your rods are far better than mine that I have had my diamonds since 2012 ??

Who tf sharpens a knife for 20 hours you trippin

Uh, bronze safety rods?! C'mon man
