Using the Work SharpHere is a collection of hand cutting tools, probably a lot like those in your shop or studio. I use two sets of standard chisels,

Before we do that, let’s start with an old beat up construction chisel that has not been sharpened with Work Sharp be-fore. It has been badly abused

Before using the Work Sharp for the first time, you need to affix the grits you want to use to the glass plates. The photo below shows the two glass pl

Putting the grit on the plate is simple. Just peel off the clear backing, align the abrasive with the center hole, and roll it on out as is shown in

The photo right shows how the grit on the second side will obscure the num-bers so marking the grit number on the face will be a handy reference.The p

The first step is to set the proper bevel angle. Put your thumb on the lower tool rest and pull up on the bar to index the tool rest to the angle desi

These side by side photos tell their own story. The only difficulty is trying to pho-tograph the newly formed polished bevel, back, and cutting edge.
