    Nice design work Josh! This model concept is coming together nicely. :thumbsup: My only comment is don't go too thick on the steel. There are already plenty of thick pry-bar folders around that don't slice worth a crap. You are known for perfect edges and blades that slice. I hope you settle on an appropriate steel thickness to exemplify those qualities.

    Thanks for sharing your thought process along the way. I look forward to seeing the finished product in steel and titanium. :cool:

    I’ve got a Hinderer XM-18 3.5 that Josh put a custom AEB-L blade in. It’s stock thickness but ground down to nothing. Th geometry of the knife makes it slice like a demon. Don’t be too worried about a thicker blade as long as the geometry is right. I would never think about using this knife as a pry bar like I would some of my stock Hinderers.

    Thanks for the input! You are totally right and I'm thinking of going with .115-.125" thick blade stock w/ a full flat grind ;)

    Good points here... yes the order of priority in cutting ability (1 making the most difference) is:
    1. edge angle/sharpness
    2. Behind the edge thickness and grind height/type
    3. Stock thickness of the blade
    So if you have the first 2 nailed then the last one will be less important and you would only notice it on really thick items like thick/dense foam or apples and such possibly. But you are correct in that it can still be a slicing demon even at .156" thick!! :)

    Josh...Since you don't have anything else going on, could you bang one of these out this weekend for me? Thanks in advance.

    Josh, I am super impressed and hopeful to be in line for one of these. You are way more than just the pretty knife sharpener dude that others have suggested. ;) Very cool to watch this evolve.

    All the best.

    Thanks man, yeah as most modders eventually do I'm looking at getting out of sharpening/mods and into making my own knives/products. I feel like it is not only a wise move for my family and retirement wise (if I ever get there lol) but also less stress - make what I want when I want with no chance of screwing up someone else's knives lol

    Thanks man, yeah I'm definitely excited about this one. I had not only a shamwari to compare but also a shiro neon and a lot of input from @Sharp & Fiery who is a front flipper fanatic so that's very helpful!

    Thanks! Here is a thread on the Kuros, I'm actually working on the first one of those for a customer tomorrow! So I should be updating that thread soon...

    Wow! Looks really great Josh. So happy to see your skill set rise to off the charts I'd carry and use the shit out of this design...looks like a perfect EDC to me :)
    Rock on brother!

    Not sure how I've managed to miss your sub-forum all this time Josh, especially with the mention above as well as the link in your sig line. Color me oblivious. :confused:

    Anyway, the asymmetrical contact point on Shiros is just another of their excellent little design elements that works well on a number of levels. As much as I like like the looks of them, I'm not the biggest fan of milled/sculpted clips as they're often way too stiff and hard in and out of pocket. Creating a smallish contact point on them only worsens the problem in the same way that narrow tires provide better traction by decreasing their footprint and inversely increasing PSI. The asymmetry of Shiro clips is not really the controlling factory here, but that the contact edge is long and narrow, spreading out the tension to decrease the traction of initial contact with the pocket seam on insertion as well making removal easier while still providing a larger contact area for retention.

    Clever, these particular Russkiy's and clever of you to follow their lead. ;)

    Well glad you made it, even if a few months late ;)

    Yeah I agree on the milled clip point... I've had a lot of knives come through my hand and a lot of terrible clips. So I will ensure my own folders have highly functional clips for sure!

    Josh with input from @Sharp & Fiery on a custom front flipper!!! I’ll take 3!

    The only input from the peanut gallery is 3.3” blade. However, 3.1” is close enough and it’s only personal preference. Oh yeah it should be full ti.. :)

    I’ll be Colman flipping that all day long!

    Little bit of CAD work today, putting the grind in. It was challenging getting it set to be the same edge thickness all the way from tip to heel but I got it finally! So... flat or hollow? whichever it will be ground pretty thin. :)

    I’d go with flat grind, unless you could do a hollow grind transitioning into a enforced tip area, either way really like the idea of a thin grind.

    I agree with these gentlemen. Flat grind and thin behind the edge makes for a winning combo.

    The CAD drawing looks very nice by the way. This is the R&D project I am most interested in from you.
