Like all CMT bits

Large BEECH wood handles with brass ferrules ensure maximum carving and detailing control

The metal to metal contact made by old metal guide blocks creates heat and friction which cause premature blade wear and breakage

The mesh design provides a truly universal hole pattern so it will work with any hook and loop system and does not require any alignment of holes - a real time saver
