The Scorpion Lock is pretty dope. I don't know if I would say, it is stronger than a tri-ad lock, but it has it's place. The knife is overbuilt. Heavy duty. I wouldn't be afraid to, pry with this thing, break down a pallet, or just cut a bag of Cheetos. It is stout enough to handle, just about any knife related, or many unrelated tasks, you can throw at it.
All that said, I prefer a little less thickness, on my blades. I do some rough work, but I still want my knife to slice well. Behind the edge thickness on this guy, just makes it a poor choice, for my needs.

Thank you for showing the difference in the grind from cold steel and the edge you put on. I would of assumed it was an error in my sharpening and think this has happened to me before. Enjoy your vids Mr Jewell 👍
Thanks for checking them out.
The gritomatic Stones just seams to work. Awesome work as always mate
They are fantastic 👌
Nicely done. Interesting knife, I've never used that type of lock. Thanks for posting.
Cheers 👊
Jef the polish really came up with the shapton stone !! I’ve never handled the AD-15 but it’s definitely a interesting knife. Thanks as always for sharing brother!!👊
The Shapton was struggling. It did polish, but it was being stubborn. In hindsight, I should have swapped over to the Venev 3/2µ diamond stone. It would have given me the polish I wanted, without fuss. Now that I think about it, I am going to go back over it with that stone ☺
My AD15 has a similarly wonky grind. It’s just one of those things. I’ve also noticed it in certain Spyderco backlocks…but the granddaddy of goofy grinds has to be Opinel. I love my Opinels and they always perform but good god. Those things wave like Indonesia on Boxing Day 2004…
funny metaphor. I had to Google it and then was like ‘oooo yea’ 😂
I’ve only got one opinel. Never sharpened it. Never used it. You’re correct though, many knives display this fault. Sad but true. My Protech Malibu was one of the worst cases I’ve came across. I really should have sent that one back for a refund. Instead, i knuckled thru it and got it close to perfect. There are still a few problem areas, and resharpening will be the same headache. For the most part, it’s even and straight now.
As always nice job sharpening Jeff! BTW, you ever try stropping after the loaded strop on bare leather? Some passes using very light pressure (10-12oz or less) on nice firm veg tan horsehide normally cleans up the apex a little more and increase the keenness. If I want max toothiness I will get the edge as burr free as possible off the stone and then straight to bare leather.
Yes I actually do this occasionally to 'clean' the apex, of any residual compound, that may still be on it. I've done it on video a few times, but it isn't a part of my usual routine. Just depends if I am on a strop with bare leather. I only have a few that don't have compound on them ( ͡~ ͜ʖ ͡°)
I do find it difficult to push cut with overly thick behind the edge blades.
Yea bte thickness can be underrated. Geometry is so important
@@Jef most definitely.
I just ended up making a little fixed blade out of some a2 I bought. I ground it very thin behind the edge. It sharpens up super easily (at around 63ish HRC), and slices like crazy because of it.
I need a set of calipers so I can know the exact measurements.
I have that exact same knife and although I like it I’m not a fan of how Thick the blade is! Not sure if I will keep it.
Yea me too. The lock is really cool but the blade thickness ruins it for me.
My AD-10 measured .038" bte, and you could feel it in the cut. I liked the grip and blade size so well that I spent the time to thin and convex the edge. It's still a thick blade and drags cutting cardboard, but I do enjoy using it now.
