.... how about a 4 layer custom (farmer with scissors) USA knife with 3 hardened aluminum liners, hard anodized a different color each, red/white/blue. Dont know how that would look, but Ive never seen it done yet.
Wrap that in black hard-anodized scales and you have just defined the new "US Covert Ops" SAK. Although is seems like no matter which country is running their covert-ops there are always too many problems (good reason to carry a SAK). I think it's because they are so secret they can't tell enough people, and no one says.... 'hey this is stupid'.
In a SAK though we could use it for late night refigerator raids, aged wood recovery from abandoned buildings, 'silencing' the BH when we're late on the chores (... by fixing it)
. Or maybe something even more grand like this story; Never Leave Home Without It!
