Wood grain. Working with wood grain
3. Cut toward a positive transition point. You are cutting into the exposed ends of the vessels. The knife will attempt to take the path of least resistance. When this happens, you’ve lost control of the cut and the wood will tend to split.
4. Cut toward the negative transition point. Cutting in this direction produces a clean controlled cut. If you cut beyond the negative transition point, you risk splitting the wood.
5. Cut from the other direction toward the negative transition point. Cut from the other direction, meeting the first cut, so the waste wood will come out cleanly.
6. Cut beyond the negative transition point. As with the cut made toward the positive transition point, the tool will attempt to take the path of least resistance and go between the vessels, causing the wood to split. Any time you allow the tool to go between the vessels (the grain of the wood), you loose control of the cut.
