So what's the problem? Traditionally chisels and plane blades are sharpened using a combination of either an oilstone, waterstone or diamond stone with a jig that holds the tool to be sharpened at the correct honing angle, many sharpening systems require a second jig to accurately set the angle of the first jig. This represents a sufficient deterrent to prevent workshop based woodworkers taking 20 minutes out of their project time to get any kind of edge let alone a decent one on their chisels; and what of the professional "On site" carpenter, do they really have the space or inclination to carry that kind of sharpening system with them? A system that the average home renovator would struggle to even set up in the first place?

The simple sharpening solution: The Precision Sharpening System is a unique solution that holds the blade to be sharpened stationary and its angle constant while a diamond stone is guided across the cutting edge (at a 90° angle to the tool's normal cutting direction) at either 25° or 30°, depending on your application, making the bevel flat and the edge true, lasting, and requiring only minimal maintenance unless chipped or neglected. We've included Preparation and Finishing Diamond stones so you can start low to gain that super fine edge that makes a cutting tool a pleasure to use. The instructions provided will have you putting a razor edge on your chisels and plane irons within a few minutes of opening the package.

Easy to use: Usage is simple! Insert the coarsest stone into the carriage of the PSS1, place the tool to be sharpened in the bed and steadied against the fence, and glide the carriage along the dovetailed track back and forth until a bright line appears across the entire width of the cutting edge. Move up to the next grit and repeat, again.

Built to last: This is a tough, solid aluminum tool, that's remarkably compact, ideal for including in any professional or enthusiasts tool bag in the shop or on the road. Get used to working with seriously sharp chisels and planes. Not only is it safer, the results achieved will be noticeably crisper, smoother!

I am a retired machinist. I found the performance quality much more than expected. It only took a few strokes to repair my chisels and hand planes to factory condition. I further found this greatly shows up the factory defects on my new Marples chisels, so I sharpened them all, they now cut feather thin.
