I'm really struggling to see the point of mechanics on a knife build when the dehumanizer is so good. The very best possible tichrome knife (purely theoretical as in practice you're never going to see that max quality tichrome bar) only has a couple of points of damage over it, deals weaker bleeding wounds, and the doubled Bloodthirst is such an insanely strong unique item property that I can't imagine life without it. The on-hit fear does work as well - combined with the daze chance from cheap shots and it's very easy to disable a whole group of enemies if you don't have the damage to kill them all in one turn.
Yes, I will see good tichrome bars. Its a bit more than just a few pts of damage. Crafted will have 5% crit chance more. tungsten will provide more crit multiplier. Also missing some shock.
Best knives outside of crafting can be provided in oculus with special stock
It's quite literally "just a few points of damage." Realistically with the quality you're going to see any time before finishing the game tichrome serrated blades will actually do *less* damage than the dehumanizer. I'd love to play this version of UnderRail you've got where 160 quality metals are dropping everywhere from the moment you step out of SGS. And thanks to its unique property the dehumanizer will be doing +50% damage when the tichrome is doing +25%, for vastly more damage total. And the crafted weapon (which ate a feat, mind you!) will have 3% more crit chance, not 5, since the dehumanizer's crit chance is above-average to begin with.
And sure, yes, you can slap a shock charge on it. Since this damage isn't multiplied on crits I don't think it justifies leveling an entirely new craft skill when you can just buy a top shelf shock blade from oculus and carry it around for dealing with robots. When critting an organic enemy for 300 damage the extra 35 electric (which eats batteries like a motherfucker) seems less important.
Ultimately it's a very minor quibble but that's sort of my point. Characters can invest hundreds of skillpoints and feats just to barely come out ahead of a weapon that's easily available the moment you clear depot A. It seems a tad too strong.
