This Keychain / pocket tool is 1/4". Each piece comes with lanyard.
This piece is the evolution of Justin's original solo, still opens a bottle the same, relocated lanyard hole, 5/16" and 1/4" Hex holes , additional dangler slot at the bottom for keys and such. This is also a good bit smaller than his OG.
