The Xi3 STS & STK have been coated with a high performance coating called Titanium Nitride, which now protects and stylizes the cutter. Used for many purposes, from aerospace equipment to jewelry, Titanium Nitride is a coating that creates an extremely durable exterior to the all stainless cutter. XIKAR's use of Titanium Nitride has created the multi-color eye-catching STS or the more subdued and sleek STK.

All Xi3 cutters features the same unique, ergonomic teardrop shape and double-guillotine action that gives the Xi and the Xi2 such powerful cutting ability in one simple squeezing motion.

All Xi cutters are the same ring gauge: they will cut a 54 ring gauge cigar in half. Depending on how much cap you cut, they will cut up to a 58 ring gauge cigar.
