Tthe renowned Xi3 cigar cutter now boasts top quality, genuine Carbon Fiber handles that are often found in luxury sports cars, jets and yachts. Carbon fiber is really millions of microscopic fibers, made of mostly carbon atoms bonded by crystals, making the material extremely strong and durable. When these fibers are interwoven, the result is a strikingly attractive pattern with incredibly strong & lightweight properties. Xi cutter blades are made of high quality 440 stainless steel with an HRC of 57. 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.
