Think of it like a rust eraser for your tools. Whether you need to shine up your shears, or just remove a bit of stubborn rust from a concave cutter, these rubberized abrasive blocks are just the thing.
They work on metal like an eraser works on paper. You can cut these block into smaller sizes with a knife to fit any shape. Use dry or with lubricant.
Because the grit is impregnated throughout the block, they last until the last little piece of block is gone; as they wear new grit becomes exposed.
