This is a Camillus/Western USA Filet Knife from the good old days, made in USA from 420HC stainless steel. 

If this big 10-3/4" inch "American Made" filet knife was your favorite fishing knife, this may be the last chance to build/repair a piece of American factory knife history. Put your own handles on this factory finished blade, or rebuild one for old time's sake. This blade is straight from the Camillus factory closing sale in 2007. It has never been assembled and will never be made the same way again.
