Klingspor Abrasive Blocks

Klingspor produces these high quality hand blocks, well suited to cleaning stubborn tarnish and rust off steel arms. In addition to the abrasive qualities, the cleaning performance is significantly increased by use of additives. Softly abrades dirt and tarnishing due to the elastic structure of the block. The grit is mixed right through the material, meaning these can be used until completely worn down; like an eraser for steel!
