I dont know if it has been discussed here or not but I think everyone needs to take a look at Havalon knives. They are made with replaceable blades and the blades are actually scalpels. They are made for hunting and are extremely sharp. I was lucky enough to use one this past year while skinning out a hog. It was a joy to use. I will be getting one very soon.
