Kemper PRO-LINE tools are crafted from select hardwood handles. The steel loops and blades are made from “knife quality” high carbon steel that has been heat treated and quenched in oil to give the blades maximum hardness and durability. Because high carbon steel takes and holds a sharper and longer lasting edge than stainless, these tools last much longer even when used with highly groged clays and plaster. All of Kemper’s PRO-LINE tools are retained by brass ferrules and firmly set with industrial adhesives to protect against water and prevent them from coming loose. In addition each handle is immersed in an oil resin bath to seal the handle against water damage and prolong the life of the tools.
Important: Since the cutting loops are made from high carbon steel which can rust, we recommend that the tools be kept clean and dry when not in use. Periodically applying a light coat of oil to the both the blade and handle will prolong the life of the tools. Should the need arise these tools can be resharpened if necessary. However, do not use a power grinder as too much heat may be generated which will destroy the temper of the tools. Kemper recommends that a whetstone, either oil or water, be used to restore your tool’s keen edge without damaging the tool.
