Blade Biter
Think of it as glass half full.It's a 2 part handle with only the top part present. It looks like it was part of a military set, but the handle knurling pattern is all wrong from anything on the Mr Razor site.
The handle is closest to this but has a Canadian head.
A bit baffling.
The half-handle forms an exact 1.618 proportion with the head. Better this way!
