I like a lot of different knives. I have several fixed blade knives made by knifebuilder friends of mine. Jason Fry is one. He was on the Forged in Fire TV show a couple years ago. I have a Buck 110 that is a great hunting knife. I have a similar locking folder that's from Cabela's (before BPS ruined them). I forget what the special steel/treatment on it is, but it was the top of the line they had at one time. Great knife as well. I had an old G96 that was the same style of knife for years and years. I ended up leaving it on the ground in the bottom of a canyon after gutting a mule deer a few years back. I had it since my dad gave it to me when I was a kid. I went back down there and found it. Then the next year I left it on the ground after gutting an axis deer. Couldn't find it that time. Getting old, I guess. Dadgummit.
I tried my dad's Havalon several years ago, and it SUCKED. Blades went dull in 5 minutes. I couldn't understand why anyone liked those knives. But then I found out that he had a pile of blades that his veterinarian buddy had given him, and that's what I had used. They were cheap Chinese crap blades (the reason the vet gave them away). I ended up buying a Havalon, and I found the 70A blades that are thicker/more durable. They're awesome. Great knife and blade. I also have a couple of the Shockey versions of the Havalon that has a folding "regular" knife blade as well as the interchangeable scalpel blade. Heavy blade is good for splitting the sternum and stuff that requires more force. Scalpel is great for skinning.
I have a couple Outdoor Edge knives as well. They're really nice. Heavier blades than Havalon, so durable. They collect bits of meat in the channel that holds the blade though, so a little more of a pain to clean.
Then I have an old Schrade that has a Bowie-ish blade with a rubber handle. It's a great knife for butchering. Not great for carrying in a backpack, but nice in camp.
