Trying to find info about this knife, a dear friend of mine is a avid knife collector and has given me some very nice knives over the years, he handed me this one on his deathbed and said I needed a real knife...he said it was a busse knife , it is very solid built and heavy duty... The only marking I can see is a very faint oval with swamp rat in it... I have to get the angle just right in the light to make out the oval or lettering so I was hoping maybe someone here knows more about it? Thanks for any help I appreciate it.
