Sharpening stones, slipstones, slip strops, honng boards, and leather strops wear with use over time. This article will teach you how to care for these sharpening tools and how to re-flatten your sharpening stones.

I was headed to do a little carving this morning on an oak branch wood spirit. I don’t usually carve large so I don’t have a large selection of mallet tools. Most of my finer quality tools are for hand carving smaller relief projects. So I grabbed my box of mallet tools to discover …. Gasps, horrors, unspeakable dire events … RUST!!!!
So it’s time to change directions and get out my sharpening tools.
The first thing I want to do is work off the rust so that I am back to clean steel. I grabbed my coarse stone as it is the coarsest stone in my kit. This is a made-man ceramic style stone that can be used dry or with a few drops of fine quality oil when I do need to use it. It’s a very inexpensive stone that you can commonly find at any hardware store.
This type of situation is the only time I would use my coarse stone with my good carving tools. It is far too coarse to create the type of edge that we use in cutting wood but it will eat the rust quite quickly. It is perfect for my tree pruner and other garden tools. Did you know that you need to occasionally sharpen your shovel and garden spade?
My coarse stone is so soft that it quickly bellies out from use. As you sharpen a tool you tend to stay towards the center of the stone. This wears the center or belly more than the outer edges. That sway or belly will be transferred directly to your cutting edge of your tool. If I use this stone as it is the tools edge will become curved to match the curve in the stones belly.
