We are proud to carry Knapp's Tool Lube, an easy to dispense, 100% organic and grass fed Mutton Tallow in our General Store. Mutton Tallow is a traditional means of lubricating woodworking tools. Reduced friction results in less effort expended and less heat build up. Mutton Tallow doesn’t interfere with glue adhesion or finishes, is slicker than parrafin, and doesn’t wear off the blade as quickly as parrafin or beeswax. No rancid odor and will last 4 to 12 months depending on heat conditions in your shop. I recommend you keep extra tubes not being used in the refrigerator or freezer. Black containers are made from recycled plastic.
