I would greatly appreciate an entire sharpening session from beginning to end. I can't sharpen for shit. I can't figure out what steps I'm doing wrong & I have no other experienced knife people around me to tell me where I've gone awry. Like I can get an edge that cuts but it's usually nothing that comes close to factory edges usually. I use worksharp freehand sharpeners, as a reference.

Yeah you did it!!! That’s a whole lot of sharpening nicely done!!!

Glad you’ve figured it out!!! The only thing that I could have added to my previous comment on your other video was to cut your edge off on your lowest grit stone. That way for sure you were starting out with fresh steel. Thanks for sharing 👊🍻

If your main use is box cutting get a Spyderco Mannix 2 or Sage 1 or Paramilitary 2 in Maxamet, or if you need a fixed blade, you could do worse than a Lionsteel M4 in M390 (at a pretty good price, too). There IS value in investigating different sharpening modalities for different uses, but a crap blade isn't going to turn into a good blade with just a change in sharpening methods.

Great job, Erica! You probably already know this, but you can actually get DMT diamond stones in both 120 and 60 grit as well, but the 60 grit is probably better suited for sharpening axes and lawnmower blades...lol.

Your Magnacut video series is "Must Watch Knife KZfaq" ... like a tv series where you can't wait until the next episode to see what happens 🤣 Thanks for taking the time to keep us in the loop, and for doing all you do! ✌️

Good Job! I was convinced, after you said it had been through several sharpenings, that it was a poor heat treat.

Those Shapton stones are amazing and worth the money - in my opinion. They work more aggressively, thus faster, than diamond in my experience. The added work of flattening and the cost is worth the time they save and how nice an edge they can produce. I use a 16000 as the final step on chisels and planes for the tertiary bevel. I don't own a low grit one, after this... probably will add one in the future. Thanks for sharing. I know MagnaCut is a new steel high end steel and as makers learn to use it they will make long lasting great knives. I haven't tried to make anything with it yet. I am not ready to 10x my blade materials costs yet :D

My theory on what was happening here is that the maker didn’t grind away all of the decarbed steel at the edge after heat treat. Even if the blade is heat treated in a foil pouch there is still a thin section where the carbon leaves the steel and the steel in that zone won’t harden. If he didn’t specifically grind away some of the metal at the edge after heat treat then the final sharpened edge will be soft. There is also some tests that show that edges sharpened with high speed belts don’t have as much edge retention as hand sharpened edges. So him using a grinder to sharpen could also play a role. I think it just took you removing enough steel at the edge to get into the hard steel. Hopefully now that you got through that you should be able to sharpen with whatever grit progression you want and still get decent results.

Good job never giving up looking foward for the updates

That’s great news. Can’t wait to hear how it does at work all day.

You are not only the best reviewer, bit Also the most passionate. Always providing correct information. You put all those boys to shame. With your wealth of knowledge and again your passion. Your family should be very proud, your fking amazing!

Good to see that you may have it sorted out

Looking forward to buying a Magnacut knife I DON'T have to re-profile... One of the main reasons for wanting to use these kinds of higher end steels is that it will work out of the box without maintenance for ages. I buy knives to solve problems and work. I don't buy knives cause I need more problems. I've got enough work in my life without having to pay for more...

I feel like the maker may have sharpened your knife on a belt grinder and ruined the heat treatment of your edge. That would explain you having to completely grind away the old edge and making a new one. Just my opinion though

Very cool that you're starting to get some better performance out of it

Hopefully you cracked the code 🙂👍 , i did some wood whittling and made a Gnome with my knife 😅

Got my 1st mgcut the other day (spyd) and was unhappy with the edge so went to work and wasn't having the best of luck. Ended up apexing on venev course/med and lightly finishing with a cheap/med corundum (!) and a handful of swipes on bare leather. -Not bad, def sticky and easily cuts stuff. lol Could use a little refining but my best so far. oh, 17 dps

A lot of times people use a grinder to put on an edge so they allow it to get too hot and ruins the heat treat on the edge. Once it's resharpened and enough material is taken off you down to that original proper heat treated blade again. I believe this may of been the case here.

Wow what a journey, that must have been ultra frustrating. Make sure to check out Home Slice's "dual grit magnacut sharpening" videos as well as Pete (Cedric & Ada's) dual grit magnacut videos if you haven't seen them, for getting a super long-lasting edge (e.g. 40% longer) by doing coarse on one side and smooth on the other. It is a bit involved of a process but Home Slice shows how.

Soft edge! I’d say the maker has had a leak in his foil pouch when austenitising and decarbed the edge of the blank! Either that or he/she has scrubbed the temper TERRIBLY when final sharpening. Youve effectively removed the compromised edge by going to a coarser abrasive and are now into good steel. Shit heat treat.

I only make knives in hc like 5160 and O1 so I don’t know if that steel would do the same but sometimes I’ve found that after heat treat there is a thin layer that is decarbonized and it takes a couple sharpenings to get thru that layer. After that they are fine. Glad your blade turned out to be ok.

Hope it holds decently cause thats a sweet blade!

This must have felt like a rollercoaster! Glad you’ve figured out how to get it to make the cut.

I just went and looked up that knife. Visited the BGM website. What a great selection of fixed blades, in about any steel one might want.

I need you to use it for longer. Then get back to us. Cause any steel would last longer than that short test. I understand it is actually working now vs failing like before. I’m talking actual edge retention vs something commonly used like O1. Can you do that for me? Cause my personally hammer forged O1 at about 60 HRC will outperform the magnacut sloyd I bought for woodcarving. It boggles my mind. Micro chips micro chips micro chips.

Thanks

Try using sandpaper on a dead smooth surface (like plate glass or stone). The sandpaper is cheap, and you can get grits up to about #3000 (which are used for polishing plastic!). I never go over #2000 myself. Start at #600, then #1000, #1500, #2000 (basically a lapping). Strop of you feel the need, but it will usually not be necessary. The motion is the same as a stropping. When using VERY hard/fine steels, DMT diamond hones are your best option. Super fine grained steels go from razor sharp to butter knife with 1 wrong stroke on a stone. I use a #120, #320 and #600 diamond to reset an angle, or to fix a chipped out blade using a KME (clone) style jig. Then use aluminum blanks with strips of sandpaper again. I will NEVER buy another stone. Makes it easy after a day's use to walk into your kitchen/garage, lay out a piece or 2 of sandpaper, and touch up your blade in about a minute or two. Note: I do not worry on a 'perfect angle'. but on a razor sharp edge. Using sandpaper on a piece of glass (or stone countertop) essentially replicates your Shapton with a piece of sandpaper. I only go below #600 for damaged blades. Might sound hokey, but it's cheap to try.

Hi Erica, what make and model is that knife?

Just found your channel. Really like it. Keep up the good work!

I thought that it needed a reprofile and also I think you could get even better results with metallic cbn stones but they are hard to find right now

So freaking happy you were able to get a decent edge on a knife that looks so appealing!!! Side note, my 50 subscriber giveaway is in 9 days! It’s not quite 3,000 like you, but you have given me inspiration that it can be done!

Haven't seen prior vids on this... But I'm gonna say this is the classic burnt "factory" edge. By reprofiling you fully removed all the burnt steel at the edge. And congrats on the Shapton. Glass stones are my favorite 🤘

I only just found this channel but I have a knife magnacut 62 hrc it should be pro forming much better at higher grit I use the shapton glass up to 6k and strops equating grit from 16k to 32k and you should have significantly better performance the cut should be much smoother and last much longer I would suggest it’s probably a heat treat issue

Subbed.. cool channel. Nice knife

I'm still on the fence. I've sharpened hundreds of knives and multiple times now and never had one dull after two passes through cardboard regardless of which stone I started with.

Young John at BGM makes great stuff. I own a few of his blades💪🏻

id love an in depth video on a new edge

So is this a revolutionary blade steel? The charts and stats from the creator look nice.

As a knife maker, I can just say, it is a steel that is new to makers and a lot are still trying to figure out the best way to heat treat and sharpen according to it's use. It seems you know your way around a knife, so I trust you are good at using a stone. It seems to me, since Magnacut is such a resilient steel, starting so high on the stone grit didn't take off the amount of material you are use to it taking off. Trying a lower grit was a smart move. So good job on getting it to perform. My guess is the maker either had to much of a convex edge on the blade or accidently heated the edge too much during sharpening the first time. and that could also be due to him or her starting at too high of a grit as well on the belt if they machine sharpened. Either way, I am not assuming the maker isn't good. Just some points I would consider first if a customer of mine came to me with the same issue.

If hes not water cooling the belt when profiling it in the manufacturing process the blade is heating up too much

I'm gonna wait to buy that blade

Why do you have to figure out all of this? The knife maker must know instead and tell his customers.

What’s wrong with convex edges? You prefer V edge?

🕵🏻‍♂️

Firsty 👊🏻👌

Solved! 👍

You need a wicked edge

Really all there seemed to be to get from this video is that BGM either messed up sharpening or burns his edges, unfortunately

Here ya go. kzfaq.info/get/bejne/l5ucrclpsaeUY6M.html

So $180 or so for a knife you have to completely reprofile from BGM. Basically he is selling a slab of steal with scales on it. "Welcome to my website. My name is John and I am 22 years old. I have been making knives for around 5 years now." That alone tells me the skill level and mindset. A inmate may have spent 20 years making shanks in prison, but I wouldn't call him a knife maker. I wouldn't call john a knife maker either.

I don't think an expensive knife (or any knife) requires a code. And if it somehow did then the maker should be able to decode it himself. You should sent Will Smith round to give him a slap.

Be more feminine and embrace your womanly beauty you are NOT a man!
