Actually my havalon should have made my list. The big test was when I shot a bull elk after a nightshift, then 4 hours later my wife shot one. Being pretty tired to begin with, any extra work while cutting is noticed. I think it took me 5 blades to gut, skin, cape and clean up 2 bulls. I only used my big knife for a couple "prying applications". I used to use actual surgical scalpels and blades, which are too small to tackle elk hide, other than the fine work. My knives are good quality pieces, and with a bit of time, I can put a decent edge on them. However, I'd guess the havalon still saved me a lot of time and effort. I think my blades have the number 60 on them. Would like to see what other options are out there.
