Sandflex Cleaning & Polishing Block - Fine
These Sandflex hand blocks are ideal to remove sap and other gunk from your tools after a work session and prior to sharpening. The entire block is similar to an eraser and can be used completely as the fine grit is embedded throughout. The fine grit will not dull tools while cleaning, so you can use it without worry after every session. A light coating of oil is recommended after cleaning high carbon steel tools to prevent rusting.
