Lets see historical Scottish weaponing...........

[St. Amish]

This is an armpit dagger (sgian achlais), made by Glenn McClain. It actually belongs to my wife, who uses it as a utility knife at reenactment events. It's well-suited to kitchen duties...!

This may be nitpicking or semantics, but "sgian" translates to knife, not dagger. Daggers are sharpened on both sides, and are typically tapered from the point on both sides.

Beautiful piece none the less.
