I never used anything on ducks or small game that I didn't use to gut deer and hogs in the field. For the last 25 years it's been a favorite Gerber Gator Serrator. It's light, ergonomic, tough, slip free, and holds a heck of an edge. Why have a special knife for this game or that when one works? I do have favorite skinners, a cleaver, such as that for butchering, but as a field knife goes, my old Gerber ain't broke. Heck, I've even filleted fish with it when I didn't have a filet knife with me.
Methinks folks make too big a deal out of hunting knives. I mean, yeah, there's the cheap junk, but there's stuff like Bucks and Gerbers that are great for an affordable price. It's a chunk of steel. It'll hold a good edge or it won't. It'll hold up or it won't. What i've got now has held up for a while now and I use my knives a lot.
I have one knife that retails now days for nearly 200 bucks, or the last time i checked it out. It was a Christmas present from my now departed father in 1975, a Case Kodiak. i't kiinda big, a good skinner, pretty knife, but its edge is delicate. All in all, I prefer my Gerber skinner I got about 8 years ago at Wallyworld for 20 bucks.
Don't get quite as sharp (have shaved my face with that Case), but it holds an edge better as it's a more robust edge.
It's funny, when I read these knife threads, EVERYONE has a favorite and EVERYONE loves to bash this or that known brand as being junk or junk now days, or whatever. Whatever. I have what I like.
I do kinda miss my old Schrade carbon steel sheath knife I had as a kid, went off to college, all the moves, don't know where that knife went. It was a great general purpose knife and skinner. Everything now days is made of stainless. There weren't a thing wrong with a decent grade of carbon steel IMHO.
Oh, I got this one stolen, but I had a fantastic little 6 dollar stainless Fiskars hunting knife for a time. I miss that one, too. It was cheap, no braggin' knife, but it sure had and edge to it and was really light on the belt.
