Blue Spruce Optima Mortise Chisels - Curly Maple

Product Description

Blue Spruce Toolworks new Optima Chisels feature a lapped and polished back with a flatness measured in light bands (the same system used to measure silicon wafers). When you unbox your new Optima Chisels, they’re razor sharp and 100% ready to go to work.

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.

In other mortise chisels, the wooden handle acts as a shock absorber between your mallet and the blade. With Optima Mortise Chisels the striking cap has a direct connection to the cutting edge through a central steel core. All the energy of your strike is delivered to the cut. The blades are taller than they are wide (except the 1/2", which is square) and the sides of the blades have been carefully ground parallel to each other. This profile guides your cut in the right direction...straight.

Each figured Maple handle goes through a proprietary infusion process that dramatically increases its durability. The result is the toughness of a composite handle with the beauty of natural wood.

The blades extend 4-1/2" beyond the ferrule and the handles are 4-3/4" long. The cutting edge has a primary bevel at 30° and a micro bevel is then honed at 35°.

The set includes the three most commonly used chisel sizes: 1/4", 3/8", and 1/2".
