A VERY SCARY SHQQT OUT On the right is the chisel I sharpened with sandpaper. Left, the one that Jim honed on his Arkansas set. Both cut the same, but I score points because mine's shiner, don't you think? One of the most frequently asked questions about sandpaper sharpening is how it compares with traditional methods.To find out, Pop Wood's Jim Stuard and I held a little contest. Jim's a whiz with Arkansas stones, and we pitted his method against mine We each sharpened a '/i" medium-quality chisel straight out of the box, then passed them around the shop for Steve, Chris and David to try.The winner? It was a dead heat. Both seemed to be equally sharp. This was no surprise to Jim or me — we both finished up by stropping our chisels with a polishing compound. Presuming that our sharpening skills are relatively equal, the sharpness of each chisel is determined by the grit of the last abrasive used. We used different polishing compounds perhaps,but they were close enough in grit that the end results were indistinguishable. Had Jim stopped at black Arkansas (about 900#) and I at l,500# sandpaper, my chisel should have been a little sharper. The conclusion? Strop your cutting tools.No matter what sharpening material you use, stropping gives you the best possible edge.
