Al Mar was a knife designer who passed away in 1992. Having started out as a knifedesigner at Gerber, he left there in 1979 to start making knives on his own. He made the Al Mar line of knives which is still beeing produced today, although by people with no connection to Al.
He is amongst other things known as the Mar in the Mar/McBurnette frontlock. He was also known for quite a hot temper and is reported to have physically chased another knife industry person around, at the 1992 Blade show, after a dispute. Al Mar is credited for having helped Sal In the beginning of Spyderco.
This quote is an Al Mar quote and this author believes it sums up nicely a lot of the things he stood for:
“Combat Knife is actually 10% weapon and 90% tool.”
