The XiKar Xi3 Bocote wood cutter uses Bocote woode which is a large canopy tree, with some specimens reaching up to 120 feet tall. It is sought for its particularly fine yet strong luster. 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.
