These are photos of the 2nd prototype: Mk40 ASAK (Aircrew Survival Aviation Knife)


The Mk Series knife project was built off a platform originated from the Mk40. Many knife designs and variations were built off this prototype and soon our tactical knife line was launched.

It took almost 1 year before the first tactical knife was developed and ready for market. Many thanks go out to the Idaho 183rd Apache Sqd. at Gowen Field for helping me with the development of the first military grade knife I made: The Mk40

I was eaten alive by millions of mosquito’s during this field testing. After 3-4 months of heat treating method sequences (back at the shop), I felt that this blade was ready for the field. It performed well. Well is sometimes…not good enough. Back to testing I went. It took some time but I did get it right.
