Based on all the names suggested so far, it appears that some need to drink less, some need to drink more, and Mike should consider that the best name for this knife may not be a name, but a number.
It should be called the “36er”, after a Colonel Colt’s Navy belt revolver of 1851.
Fun giveaway, Mike! Here are my humble entries:
Spaghetti Western
Gunslinger
Peacemaker
Smokewagon
Muzzleloader
Sorry, missed that.I already suggested your first 2.
