Richard Maguire AKA The English Woodworker has a new series of videos on sharpening. So far four of the planned eight videos are up and running. If you are not familiar with Richard he build and sold beautiful work benches totally by hand for many years. He is also a great teacher and a hoot to watch. The first three videos deal with my way of sharpening, using oil stones with simple high carbon steel. The fourth is about A-2 and thick irons with the use of grinders and water stones. The most surprising part is when using water stones and A-2 he makes the case for use of a jig. In fact he makes a strong case for use of A-2 in modern planes for finishing difficult woods. I may not be quite so dogmatic about O-1 and thin irons on natural stones in the future.

This is not a commercial but if you have an interest in sharpening iron, and what woodworker doesn't, you should check out this series.
