USE/CARE OF HANDTOOLS & MEASURING TOOLS - OD1621 - LESSON 2/TASK 2
(4) Do not carry open knives in your pocket.
(5) Do not leave knives where they may come in contact with the body,
or in such a position that they could cause injury to others.
(6) Carefully put knives away after use, in a sheath or container, to
protect the sharp cutting edges from contacting other hard objects.
(7) Before storing, wipe all metal parts with an oily rag.
(8) For long-term storage, apply a thin film of rust-preventive
compound on all metal parts, cover the cutting edge, and store in a dry
place.
d. Maintenance of Knives.
(1) Sharpening.
(a) Most knives are sharpened on a medium or fine grade oilstone
with a few drops of oil spread on the surface. Hold the handle in one hand
and place the blade across the stone. Press down with the fingers of other
hand and stroke the blade, following a circular motion as shown in figure
105 on the following page.
After several circular strokes, reverse the
blade and stroke the opposite side, using the same type of motion. Avoid
grinding the blade; use a light, even pressure.
A thin blade overheats
quickly and can lose its temper. The wire edge or burr that may be left on
a knife blade after sharpening may be removed by stropping both sides on a
soft wood block or a canvas or leather strap.
(b) To sharpen a drawknife blade, place the knife blade on the
oilstone and tilt it so that the bevel edge lies flat on the stone. Make
certain the oilstone is high enough on the bench to provide clearance for
the knife handles. Use both hands and, following a circular motion, rotate
the blade across the stone so that the entire length of the bevel contacts
the stone. Repeat the sharpening procedure on the other side of the blade.
The wire edge can be removed by stropping both sides on a soft wood block or
canvas or leather strap.
