By far the largest producer of S&W marked pocket knives ( folders) is Taylor Cutlery Co. It was their practice for many years, and may still be, to make dozens of different style S&W marked knives, send them to the S&W marketing staff for selection as to which ones would be authorized as S&W knives and put in the S&W Knife catalogs. A small percentage of submitted examples would be selected and authorized, the rest went back to Taylor, who sold them by the 100s to a S&W collector friend of mine and to other secondary market knife sellers. You see those knives on Ebay, at guns shows and as big box sporting goods "sale" items in the Sunday paper ads. $10 to $20, take your pick and worth the money, but they won't "letter" as official S&W knives.
