1/8 Inch Richter Extra Unhandled Bevel Edge Chisel Blank, Cryogenic Treated Cr-V Steel Hardened to HRc 62, Stainless Steel Ferrule… (1/8 Inch) - Narex 815053

• To commemorate its 100 anniversary, Narex developed a new line of Richter Extra premium bench 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 is made from the finest materials available, have undergone superior heat treatment and been manufactured using the most stringent manufacturing processes. The new line of Richter Extra chisels will rival any premium chisel on the market today. These unhandled chisel blades are made in the Narex factory in the small village of Bystrice in the Czech Republic. The Narex factory was founded in 1919 by Mr. Vaclav Richter, a local blacksmith who began producing chisels and gimlets. To this day, Narex is best known for making an extensive range of high quality, reasonably priced bench chisels. 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. Cryogenic treatment cools the steel down to −190° C (-310° F) using liquid nitrogen which 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 (.5mm) allowing reach into very tight spaces, making them the perfect chisel for cleaning out dovetails. The front bevel is ground at 24 degrees. Blanks come with square, untapered tangs. Stainless steel ferrules have an OD of 0.750 inch, ID of 0.670 inch, and height of 0.710 inch. The ferrules have inside bevels for easy insertion and are properly annealed (hardened) to prevent splitting when tangs are driven into the handle. Each ferrule has a lasered Richter logo. Blade Length: 4-3/4 inches. Tang Length: 1-1/2 inches. Total Length: 6-1/4 inches
