OPTIMA™ Dovetail Chisel - 5/16 (0.313) 7.9mm

The unique blade shape of Blue Spruce Toolworks Optima Dovetail Chisels makes them perfect for light chopping, paring and precision fitting of your finest joinery. The 4" long, 1/8" thin blade is sized just right for close-up, intimate work, allowing clear visibility of your material. The unique concave side bevels allow the chisel to pare into the tightest corners of dovetail joints. They have a refinement, balance and feel that is unmatched. 

All Blue Spruce Toolworks Optima™ Chisels feature a lapped and polished back with flatness measured in light bands (the same system used to measure silicon wafers). This incredible surface results in edge sharpness unlike any other chisel in the world. You will never have to flatten the backs of your Blue Spruce Optima chisels, ever. And, when you unbox your new Optima Chisels, they’re razor sharp and 100% ready to go to work. No sharpening, no honing, no nothing. 

Perfectly sharpened is a great first step, but how does it hold an edge? Each Optima Chisel is machined from A2 tool steel, heat treated, double-tempered, cryogenically treated, ground, lapped and polished to perfection. The tempering and cryo treatments result in an incredibly fine grain structure and a hardness of Rockwell C-60 to C-62. Blue Spruce Optima chisels take and hold an edge like no other.
