CARP S-SERIES PARTING TOOL (WITHOUT HANDLE)
CARP S-series parting tool (without handle)
A parting tool is the easiest tool there is. To chisel off your workpiece or to indicate measurements. This CARP parting tool is straightforward. 2,5 mm wide and 20 cm long. High-quality milled steel so you have to walk to the grinder as little as possible....
Handle
A handle for a woodturning chisel is sometimes long and sometimes short. Depending on the function of the chisel. A scale gouge or roughing gouge needs a long handle, a profile gouge needs to be manoeuvrable and so a short handle is useful. Furthermore, it is useful to easily recognise the handles when they are hanging in the rack. For the push-off chisel, you don't need a long handle. Find handles here. Often a changeable handle is handy, you can find those here.
CARP chisels
Carp chisels are made of hardened HSS M2 steel. They are forged and/or milled, then hardened to 63-64 HRC, then ground and polished.
S series
CARP chisels from the S series are milled from HSS M2 steel. They are no longer forged. Forging hammers change the structure of the steel, milling does not. Milling chisels gives the manufacturer better control over the quality of the end result. Many US chisel manufacturers (Thompson, Robust, Carter & Son) no longer forge chisels at all. They only mill. The S series comes without a handle. So you can choose the length of your handle, or make your own. Or you can opt for a changeable handle.
Harden
How good a chisel is depends largely on the hardness and toughness of the steel. So a lot of thought goes into hardening chisels. This is a lengthy process. It starts with heating the steel. This is done in absolute vacuum. Then the chisels are hardened in 3 steps, before undergoing another process of heating and cooling. Here, temperatures of up to -185 degrees are reached (in liquid nitrogen). Quality is strictly monitored. Between 5 and 10% of each batch of chisels is tested for hardness and toughness.
