Located in the U.S.A., we have handcrafted tools for the Ceramic Arts for over 50 years. Here at Kemper, we have employees that have been here for over 30 years. Today that says something. Each employee takes great pride in the quality of their work. Rewarded for quality, safety, and even birthdays Kemper has proven to be a successful family environment in which everyone thrives. Kemper truly is “The American Dream”.It all started in 1947, a friend asked Jack Kemper to make a tool for his class. Jack made his first ceramic tool in his garage in California. As you can guess, soon everyone wanted one of these tools. The first tool was functional and well constructed. However, Jack was just not satisfied and took his simple design and improved it with the intent of making it comfortable in the hand of the artist as well as a nice looking tool.
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 grogged 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.
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.
