Modern Abrasive Combination Fine/Coarse Grit Bench Stones
When more than one grit size is necessary to resharpen a cutting edge, a craftsman will often use a combination stone to lessen both the expense and the inconvenience of using two single grit stones. Use a silicon carbide stone for sharpening quickly or an oil-filled aluminum oxide stone for restoring a long lasting edge.
Features:
Aluminum oxide stones are used for finishing of hardened steel.
Silicon carbide stones are used for finishing of soft steel, cast iron, non ferrous metals as well as for edging of cemented carbides.
