It came with an edge that I used. Never sharpened it. I never even sent it into buck for sharpening and it was lowly 420HC.
In truth, I probably grabbed something from the kitchen after bringing the game home most of the time. Most of the knifes were sharp enough, I guess, or had the prepared chef sharpen sheath things though I wasn't really allowed to use those for rabbits or squirrels, which was 90% of what I cleaned. Not including fish. Never sharpened a fillet knife either. Probably just replaced it if it ever god dull enough but I think we just thought everything was sharp back then. Push harder and slice more times until the meat separates. I "know" differently now but everything seemed to work fine then too.
Most of my family's "life skills" can be attributed to figuring things out vs knowing a lot of different skills that we brought together. For example, using a hack saw to clean fish when the knife wasn't handy. Not traditional but it worked. I know we used the hack saw on deer a lot too but that's not too creative since they have bone saws, but we didn't know there was such a thing. Honestly, probably used saws and scissors for a lot more than they were designed for instead of knives. Can't say my step dad ever sharpened his 110 in the decade or so I hunted with him either. I don't know if he did something with it at work but I never saw a sharpening stone around. Maybe he hit it on the bench grinder?
