A properly made V-cutter, which is rarer than it should be — most crack wrappers or cut too shallow to be worth using.
Takes up to a 64 ring, with a razor-sharp blade in an all-metal body, contoured so it doubles as a comfortable grip. Black, silver or gunmetal.
V-cutter · Fits up to 64 ring gauge · All-metal construction · Contoured body · Xikar lifetime warranty
If a bad V-cutter has put you off the cut entirely, this is the one to retry with.
