What do you guys think about this shark I which I made in photoshop? The blade is 12" and overall length is 17.5 Same like a KVLUK without the skull crusher.

I know the pointed belly should decrease functionality when chopping straight through wood and also be more susceptible to blade wear at that point. However in a pulling motion through softer things it should create much more damage since it hooks in instead of sliding along the surface like a smoother curve would.
I think it is time to get some O1 tool steel flat bar and start drilling, sawing and filing it into shape to see how this shape performs. The purpose would be to evaluate it before asking HI to do a custom version. Additionally if I do a good enough job on the mock-up then I will keep using it too of course
What thickness would be good? Can O1 be made thinner than spring leaf Kukris without compromising strength or does it have to be even thicker? For reference my KVLUK which I think would be sufficiently strong is 5/16 at its maximum thickness.
A slab of
1/2 x 3.5 x 18 inch would cost $115
with
3/8 inch thickness $87
with
5/16 inch $73
1/4 inch = $66
What would you pick?
Thank you!
