Metal Plate

 6" laser cut plate with a 3/16" - 5mm center hole . Use this to attach your abrasives to flathone type machines. Works well with Scimech, and some other 6" flathone systems. Does not work well with Wolff's Hira-to Scissor Sharpening Flathone which has a larger center hole, it will fit the Hamaguri machines which has a smaller pin.
