Chisels are an essential part of every woodworker’s kit. Preparing chisels for precise work differs in some important ways from preparing plane blades. In this DVD, a companion to David’s DVD on the treatment of plane blades, he explores these differences. His techniques employ waterstones and a simple triple bevel to speed the honing process and get a razor-sharp edge in minutes.

EXCELLENT DVD! David Charlesworth - THE BEST TEACHER!
Well, having seen all 3 of the other dvd's, this one has high and low spots.
Low, its not very long. Does not cover chisel technique, just sharpening.
High, it does fill in some of the gaps from the other plane videos.
In Mr. Charlesworth's usual fashion, he is very precise and articulates his approach clearly.
Well worth a rental, but not what I was expecting given the other series.
He is sharpening to a micro-bevel, which may or may not be your preference.
Clear and thorough presentation. A bit slow moving and repetitious, but the content is excellent.
Completely covers the subject of sharpening chisels as well as detailing specific joinery techniques using them. To quote Charlesworth:
"Chisel work is at the heart of all of the most sophisticated joinery"
Heeding this advice, it will benefit all woodworkers to learn about preparing and using chisels to ultimately help us in efforts to perfect our joinery tasks.
As the title suggests, this DVD details the subject of a sharpening chisels for use in the workshop. Specifically, in this DVD Charlesworth highlights both the concepts shared with sharpening plane irons as well as new techniques that are unique to sharpening for chisels.
Starting with the definition of sharpness as the intersection of two polished surfaces, and the statement that the quality of the edge is only as good as the quality of the polish on the surfaces, Charlesworth takes you through the process of flattening the backs of chisels and honing their edges.
This instruction starts with a discussion of how to use Japanese water stones to sharpen (including the flattening of stones with a simple technique using wet/dry paper on a flat plate). Two distinct movements are discussed for flattening the chisel back with an interesting aside on why a slight hollow on a chisel back is actually a desirable trait as opposed to a belly or bow. Along the way, Charlesworth touches on different scratch patterns and how to use them to your advantage to determine when to move to the next grit stone as well as why to avoid using the second sharpening movement on narrow chisels.
The discussion on honing the bevel of chisels covers a triple-bevel technique for fast sharpening. This includes a rationale for each of the primary and micro-bevels and their angles as well as a discussion on when to re-grind the tool. Also covered was a technique for using a jig and a coarse stone to correct for an edge that may have been ground out of square.
Charlesworth shows a nice water stone holding board for use when sharpening and as an added bonus the plans for this board are included as a PDF on the DVD.
The material covered on this DVD is a nice complement to the information on the DVD covering sharpening of plane irons. Distinctions are made to compare and contrast the two techniques. The techniques for chisels are different and for good reason. Charlesworth emphasizes these differences as well as their merits for use with chisels.
