3 Piece Dovetail Chisel Set of Richter Extra Bevel Edge Chisel (1/4, 3/8, and 1/2 inch) Cryogenic Treated Cr-V Steel Hardened to HRc 62 Ergonomic Ash Handles Stainless Steel Ferrules - Narex 853653

• To commemorate its 100 anniversary, Narex developed a new line of Richter Extra Chisels named after their founder. The Richter Extra chisels are the finest chisels Narex has produced in its 100-year history. This line of chisels are made from the finest materials available, have undergone superior heat treatment and been manufactured using the most stringent manufacturing processes. Richter chisel blades are made from the highest quality Chrome Manganese (Cr-V) steel using traditional drop-forging methods. Blades are then hardened, cryogenically treated and tempered to achieve a minimal hardness of 62 HRc. Following initial hardening, cryogenic treatment is performed which cools the steel down to −190° C (-310o F) using liquid nitrogen. This alters the mechanical properties of the steel at the molecular level greatly increasing its strength, toughness and wear resistance. Subsequent fine-grinding and polishing ensure a mirror-like surface with ultra-thin sides allowing reach into very tight spaces, making them the perfect chisel for cleaning out dovetails. Chisel handles are made of domestically and responsibly harvested European Ash known for its strength, toughness and attractive grain. The ergonomic handles are sanded and then receive a friction shellac finish for maximum protection, comfort and control. Solid stainless-steel ferrules protect the handles from splitting, and leather washers absorb the shock of mallet blows. Set comes with the following sizes: 1/4, 3/8 and 1/2 inch
