Does anyone know when the first 111mm Vic SAKs were introduced? (Reviving this old thread.) Since I carry the Adventurer (2-layer enlarged Tinker), I was trying to figure just when the 111mm models were introduced. Can't remember how long its been since I started carrying the Adventurer, but it certainly has been more than 10 years. I carried a Tinker in the 80's and believe I switched over to the 111mm size in the 1990's.
