Sandflex Tool Cleaning Blocks

Whether you're cleaning bonsai tools, polishing metal surfaces, or removing rust and resin buildup, the Sandflex Tool Cleaning Block is a versatile must-have. Made from a semi-flexible rubber compound infused with abrasive grit, it works just like an eraser—simply rub it over the surface to restore shine and remove grime.

Unlike steel wool or wire brushes, Sandflex won’t scratch polished finishes or dig into edges, making it perfect for maintaining high-carbon steel tools, stainless steel shears, blade surfaces, and more. The block can be cut or carved to fit tight curves, concave cutters, or detailed surfaces.

Used dry or with water, oil, or a mild cleaning solution, it continually exposes fresh grit as it wears—so it never dulls and won’t clog.

Dimensions: 3 1/4" x 2" x 3/4"
