You would think they could be twins since they have the same handle profile. Turns out they are twins.
Bob calls this his Twin Folder; his version of the two bladed folding pen knife. Style-wise, it's a cross between a Canoe (handle shape) and a Muskrat (blade shapes).
It does have one unique design: the two blades share a common center lock bar to help keep it thin.
He made this model in two sizes; Medium and Small (I'm pretty positive Bob never made one in Large).
The one above is the Medium, Small on bottom.
The one above is the Small, Medium on bottom.
Since the Medium one had Flat ground blades, the Small was ordered with Hollow ground blade. Same Large Nail Nick opener.
Gerber Legendary Knives licensed the Small Twin Folder and made a Production version called the Double Take.
