In the past, before the easy availability of lumberyards and finished materials, a drawknife was an important tool. They can still be purchased new and found in garage sales and antique shops. If you intend to do any woodwork after a disaster, they are something you should own and learn to use.
A drawknife is a traditional woodworking hand tool used to strip bark off logs and shape wood by removing shavings. It consists of a blade with a handle at each end. The blade of a drawknife is usually long and narrow with a beveled, or angled, side and one flat side. The handles at each end of the blade are usually perpendicular or continuous with the blade. Long drawknives are typically used for tasks such as debarking logs and shorter knives are used for finer woodwork.
A drawknife is often used to debark trees, or to create roughly rounded or cylindrical billets to finish on a wood lathe. It can be used to flatten wood to make planks. They work best on green wood. Green wood is wood that is still moist because it has not been dried.
To use a drawknife, you grip both handles and draw the knife along the wood toward your body. The downward pressure on the handles determines the depth of the cut. For ease and safety reasons, the beveled edge of the blade is usually angled upward and the blade is rarely pushed away from the body.
When using a drawknife work from the center of the piece to the end, not the entire length all at once. The operator then reverses the piece in the shaving horse and works the other end.
Shaving smaller pieces of wood with a drawknife is usually done while seated at a shaving horse. A shaving horse is a bench that clamps the wood in place. You straddle the bench and step on a bar that causes the clamp to hold down on the woodwork. (I will post plans for a shaving horse tomorrow)
A common uses for a drawknife is stripping bark. Smaller logs are locked in place with a vise or a shaving horse; larger logs may stay in place from their own weight. To debark pull the blade with consistent pressure and fast movements toward your body, repositioning the log as needed.
There are quite a few different styles and shapes of drawknives; find out what works best for your purposes. This is a tool that requires a certain amount of skill, get your drawknives now and learn to use them.
