This
concludes our honing lesson. It's really the first step. Practice
is the key, and with time you will become fast and steady in your
sharpening. With sharp tools accuracy and control of cut becomes
easier. Plus, you eliminate the very real danger of dull blades,
which won't cut wood but easily cut flesh. Once you become comfortable
sharpening chisels, try sharpening a plane blade. The sequence and
technique are identical although the thinner blade makes it a little
harder to keep the bevel flat on the stone.
As
you repeatedly sharpen a hollow-ground tool, the hollow will disappear
and you will eventually have a flat bevel. While it is marginally
easier to sharpen a hollow-ground tool, there being less metal to
remove, the technique will continue to work very well. It's tempting
to conclude that if a well honed tool never got nicked or damaged,
and the secondary bevel were not allowed to grow, there would be
no reason to ever grind the bevel. But the sad reality is that wood
is hard and long hours of digging and slicing it take their toll
(even without nicking and edge on a vise or clamp). The edges of
plane blades do dull and thicken beyond the capacity continued honing
to correct. It's a bummer, but in the middle to long run, the abrasive
quality of wood upon steel will require even the reflattening of
the rounded backs of blades, as well as the heavy metal removal
needed to bring back thin contours to obtuse edges. This can be
slow and laborious even with water or diamond stones, or that old
standby of professional woodworkers, the grinding wheel.
Nevertheless,
you can postpone the eventual need to do wheel grinding by frequent
honings with the tried and tested methods described in this lesson.
Strop blades often. When that fails, use the Arkansas stone until
the medium stone is needed to get the edge back to honeable thinness.
