Far from being a nail breaker, the opening is both smooth and easy with no discernible grind. The main clip point blade is 3-1/8” long, and has a “Colonel Coon Knives” blade etch with a tang stamp that reads “Col. Coon USA”. The secondary spey blade 3-1/4” and the tang stamp reads, “Hand Made in the USA”. It’s 4-1/8” closed, and the handles are about 9/16” thick.
