Every book on sharpening chisels starts with pages of instructions on how to flatten the back. The authors devote so much attention to the subject because chisels don’t arrive ready to use or even with a reasonably flat back…until now.  Blue Spruce Toolwork's new 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 its edge? Each Optima Chisel is machined from A2 tool steel, then double-tempered and cryogenically treated. The tempering and cryo treatments result in an incredibly fine grain structure and a hardness of Rockwell C-60 to C-62. These chisels take and hold an edge like no other. 

Optima Bench Chisel blades extend 4-1/2" beyond the ferrule. The standard chisel handles fit most hands comfortably for both mallet work and delicate paring cuts.  Resin-Infused Figured Maple
