I want to be able to grip it hard, use it and not get a cramp or hotspot.
I want it to be durable enough that above said use does not loosen up the blade, lock or anything else.
I'd prefer the clip point steel blade to be run on the hot side for that steel, with the heat treat and temper designed around performance, wear resistance and not corrosion resistance.
I would love to have a full size tough lockback in O-1( rc 61), W2( rc 61-62), 52100( rc 62), cruwear ( rc 62-63), 3V ( rc 60), or 10V/A11 class ( rc 63.5-64.5)
I would love a nice, subdued, plain wood ( oak or black walnut) grip and german silver bolsters. Blade length 3.75 to 4.00 inches.
Once again, lockback must be sturdy enough to last a lifetime with care. The geometry is for cutting & slicing, not prying. Sharp with thin behind the edge is very good. Lanyard hole is nice but I can do without if needed. Matching leather belt pouch would be nice. Liners could be stainless, as well as spring.
stainless steel blades need not apply. I'd get a special one of those to my design later using S110V at rc 63.5.
