The set of 6 chisels includes: 6, 10, 12, 16, 20 & 26mm.\nSupplied in a stained beech presentation box.\nThe original 8105 range of Narex chisels have a few characteristics that differentiate them from other general purpose bevel edged chisels in this price range. Narex chisels are accurately machined, nicely balanced, isothermally hardened, and have the light pointable feel of a proper bevel edged chisel.\nIsothermal hardening is much more accurate and even than induction hardening, producing a uniform and consistent hardness of RC59 through the front 75% the blade. Handle: Stained beech with chromed steel ferrules.\nNarex uses Chrome Manganese steel, which was specifically developed for making edge tools using this process. In use it is indistinguishable from other good quality high carbon steels but is particularly nice to sharpen, with excellent stone feel and feedback. The backs are very good, typically only taking a few minutes to prepare.\nApproximate Measurements:Size&nbs6
