Looking to find more information on the Schrade Walden Greenskeeper Knife that I have. In checking the Internet, I found that these particular knives were manufactured between 1953 to 1958; but have not found much else. There is a main spear blade and a secondary "v" shaped tip weed pulling blade; a ivory celloid handle, brass lining and nickel silver bolsters. The knife measures 4" long when closed.
