Lets you use a common 4" x 1/2" triangular India stone in the Series II stoning fixture. Completely supports stone along its entire length to help prevent breakage and extend stone life. When the edge becomes dull, simply loosen the fixture and rotate the stone to present a new edge. Use as a hand-held tool for any stoning application where a flat, sharp edge is required. Rigid housing of 6061 T6 aluminum with a clamp pad and spacer of tough polyethylene securely grasp the stone and prevent slippage. Stainless steel bolts maintain proper tension while ensuring easy disassembly and adjustment.
