Wood Cutting Tool or Scissor Sharpening Tips
1.
Preserve the correct angle. The cutting angle is the angle of the cutting
edge to the face of the tool. The best angle for each tool depends on the tool
and the material being cut. In most cases, it is best to reproduce the angle
originally supplied by the manufacturer on your tool.
2.
Preserve the edge shape. Each cutting tool has a unique edge shape best
suited for its purpose. It may be curved, straight, beveled or other. When
sharpening, be careful to retain the edge shape of the tool.
3.
Do not overheat. Use a wet, low speed grinder to sharpen tools. A high
speed grinder will heat up the cutting edge of the tool, removing the hardness
of the edge. A soft edge will not remain sharp for long and will not cut properly.
4.
Burnish or hone the edge after grinding. Grinding produces an
approximately correct cutting edge. Some burrs or scratches will always
remain on the cutting edge after grinding. For best results, take the time to
hone (using a sharpening stone) or burnish (using a hardened steel honing
tool) the edge before beginning work.
5.
Protect the edge from damage. The sharpened edge is extremely thin,
sharp and subject to damage. Store your cutting tools with care to prevent
damage to the edge from banging against other objects or from corrosion.
6.
Touch up the edge periodically. Occasionally touch up the cutting edge of
your tools with a honing stone or burnisher. This will keep your tools sharp and
ready for use, and will result in less wear to the cutting tool than repeated
grinding.
7.
Grinding wheel direction. In most cases with chisels, knives and scissors,
position the tool so the grinding wheel will turn from the base of the tool toward
the edge of the tool. With axes and blunt tools, have the grinding wheel rotate
from the cutting edge toward the base of the tool.
8.
Inner curve gouges. In this manual, most instructions are given based on the
beveled edge of the tool being on the outside. In some cases, the beveled
edge of a gouge is on the inner or concave part of the cutting edge. With tools
of this type, a special profiled grinding wheel is required for sharpening.
