Thicker than conventional firmer chisels, registered chisels have the inherent
strength to chop and lever out waste wood. Tapered from the shoulder to the
cutting edge to give additional strength. Also suitable for less rigorous framing
applications.

The trapezoidal shape of these mortice chisels – they have a 2 degree side
relief angle – prevents them from binding in the cut. Heavy section makes
this style ideal for levering out waste wood in locks, hinges and tenons.
Fitted with boxwood handle.

Traditionally used by cabinet- and pattern-makers for shaving thin slivers of
wood. These paring chisels feature a long, flat, thin blade which
tapers towards the cutting edge to give the finest of cuts when
cleaning out grooves. Normally used for hand paring with one hand
on the handle and the other controlling blade. Bevels on the top face
enable access to the more difficult corners. In skilled hands a paring
chisel causes wood to be removed effortlessly. Fitted with boxwood handle.

Used primarily for squaring up and cleaning waste wood from the corners of mortices.
The two cutting faces meet at 90 degrees to give an accurate, square corner. Bevel is
on the inside. Fitted with comfortable boxwood handle. To sharpen a corner chisel place
it in a vice and hone each of the inside cutting faces separately with a diamond hone or
file. This gives you a clear sight of exactly what is being honed.
DRAW KNIVES
565
Traditional English design. Still used in many traditional crafts by bodgers,
chair-makers, period furniture-makers, cricket-bat makers and green
woodworkers. Designed for shaping wood and removing bark.
A simple tool which can be used either aggressively for rapid stock removal or in
a very delicate manner to give a fine finish. Mainly used on the pull stroke.
