From the Manufacturer
The 87 series Chisels strike a perfect balance between price and performance. Blue polypropylene handles are designed for mallet and occasional hammer use. Blades are heat treated to within 1-Inch of the bolster to maintain a nice edge and ensure long bench life. Blades are fully machined on all faces and finished honed to 30 degrees - ready for use. Each chisel comes complete with a plastic tip guard to protect the chisel and the user.
