Greetings all. New to the blade forum but have collected/used/carried knives since I was 11 or so. Have a knife that I got in trade years ago from a co-worker. I know something about them, but would like more info. It is marked "Wood Knives mk.1 Venice calif." Acid etched. with Pat. #3702501 on the reverse. Nickel silver fittings and a dark maroon/brown micarta handle. I know there have been several variations of this knife. Some production and some handmade. This looks to be handmade based on the solder lines around the brass back liner. Picture available if anybody needs it. Not looking to sell, just trying to keep up with the stuff I have and maybe get an approx. value. Great condition. Thanks.
