2. Check Sharpness
There are many ways to determine if your turning tools need sharpening.
- Thumb Test: Run your thumb along the edge of a sharpened tool and feel for a bur. You should not rub your finger on the sharpened edge of a tool as this could cause injury.
- End grain testing: Take a piece softwood, such as cedar, and clamp it on your workbench to test the sharpness and sturdiness of your skew or gouge. If the gouge cuts through shavings on the corner of the end grain, it is sharp. The tool will not be blunted if it cuts out shavings.
- Light Test: Place your chisels or gouges in bright light. They will reflect light if they do not reflect it. If they do, they will be sharp.
- The paper test: This is a test that’s more useful for skews and not bowl gouges. A piece of paper should be held at the edge. The tool won’t become dull if it is straight and clean. If the paper is not straight, it’s worth sharpening.
