M-Power, the company that brought us such products as the Perfect Butt, the Tri-Scribe, and the Precision Sharpening System, now brings us chisels with replaceable tips from Sheffield, UK. This isn’t the first time these chisels have been covered — The Woodworking Magazine blog actually covered them several weeks ago, but now you can actually purchase them online.
Somewhat like a utility knife, when the Merc Pro chisel gets dull, rather than sharpening it, you can just unscrew the blade, replace it, and keep working. M-Power manufactures the inserts from high-speed steel (HSS) and titanium plates them. They claim the inserts will keep their edge up to 5 times longer than carbon steel, plus you can resharpen them just like a normal chisel if you want.
M-Power gives the chisel a “split proof” acetate handle and tops it with a hardened and tempered strike cap. They finish the chisel body itself with an almost mirror-like polish. You can find 1/2″, 3/4″, and 1″ chisels for just under $50. The standard inserts run about $8 to $9, the three-sided inserts run $10 to $11, and the 1″ serrated insert runs $10.
