The 152 pattern was used by Peterson Publishing in 1976-77, along with the 154 pattern, for promotion of two-year subscriptions. Shields on the black sawcut Delrin handles were stamped with the magazine names, "Guns & Ammo" on the Sharpfinger, and "Hunting" on the Drop Point Hunter. I’ve not seen both patterns with both stampings. They used the production 1095HC blade blanks and custom "SCHRADE over U.S.A." tang stamps. As an interesting aside, after years of searching, I finally acquired an example of this knife in it's original shipping box from Peterson. It contained a SAS17 pouch sheath and the box was post marked 1983. So did Peterson order remainders in 1983 when their supply of 1983 promo knives (a different brand) was used up, but obligations were still outstanding to subscribers?
