Wood Chisels
Woodworking chisels are used to
rough out joints, and also to pare down pieces for a perfect fit.
The right chisel for the job will lead to a successful
end.
Woodworkers of
all sorts use chisels for everything from paring down a thousands
of an inch off a mortise, to opening a paint can. We have invested
heavily in paint can openers, so that isn't necessary in our
shop!
A subject as seemingly small as wood chisels, is quite broad in
scope. Consider all the different types of specialty chisels, and
it's surprising just how large a variety there is. There are
very large slicks for timber framing, dovetail chisels, mortising
chisels, bench chisels, short bench chisels, paring chisels, skew
chisels, corner chisels, dog leg chisels... The list seems to
be endless.

Then there are the broader categories, meaning Western made,
English made, Japanese made, blue steel, white steel, etc...
Having used most of them at one point or another, I can say my
favorites are hands down, Japanese chisels. In our shop we have
maybe eight sets of chisels. What I used to think was a great set
of bench chisels, has been demoted to such tasks as removing
glue or very rough work. The edge seem to chip rather easily,
without major abuse. At least no more than they were designed
for.
Then we have a rough mortise set, and again when we bought them,
we thought they were great quality tools. These too, have received
demotions. Even after having spent the time to "tune" these
chisels, they are no match for their Japanese
counterparts.
Tuning a wood
chisel
By tuning a chisel, I mean working the front, and back of the
chisel to a point where they want to cut wood!
Start with flattening the backs, using sharpening stones,
begin with a rough stone, and work through the grits
to fine stones, and then on to a leather strop, charged with
rouge. My preference for sharpening stones are the water stones, as
opposed to oil stones.
Another very effective way to finish off the
sharpening process, and my own personal preference, is to take a
few small pieces of M.D.F., and "charging" them with diamond
paste. This is a paste with diamond particles in it. Again start
with the rougher grits, and move through to the finer grits. It is
important to clean the chisels, sharpening stones and
M.D.F. blocks, prior to switching grits. Otherwise you'll
contaminate the finer grits.
I take them to a point where you can actually see
your face in them. Then the cutting edge receives the same efforts
in achieving a very sharp, polished edge. While this may sound
somewhat extreme, anybody who has taken the time to tune a chisel,
will tell you it's time well spent. These "tuned" chisels will cut
the end of a board with so little effort, leaving a polished edge
in their wake.
It's actually amazing to realize how crude these tools are when
received from the factory. (of course some are worse than others).
If you ever saw the edge under a microscope, you'de
be surprised at the edges that leave the factory.
Japanese chisels on the other hand, generally come flattened and
polished, with an edge that is simply amazing. At least the better
quality ones. These chisels are laminated with a soft metal, hand
forged to a hard metal. I've seen sets of ten chisels that were
Seven Thousand Dollars! These are truly works of art in there
own right. I unfortunately, am not the proud owner of such a set.
The workmanship in these tools is impeccable. I can't imagine what
these guys could do with wood.
