I currently sell and have sold many types and styles of custom knives.  Eugene & Sons Custom knives of Palmdale, California make outstanding knives. Simple in design, clean lines but great working style knives. I have had several of their knives and currently have the 2 shown At Lee’s Cutlery.  However I don’t know much about them nor able to find out much.  If there is anyone out there that can enlighten me about the maker, please get in touch.
