Why do many woodworkers lay out joinery with a marking knife instead of a pencil?
A knife line is crisp, while a pencil line has width.
- A knife line is crisp and has no real width ✔
- Pencil lead dulls saw blades
- Pencil marks cannot be sanded off
Why: A pencil line has width, so you must guess which edge to cut to. A marking knife makes a crisp, fine line that a chisel or saw can register against. Decide which side of the line is waste before cutting.
Huh, didn't know that: Story sticks, shop-made strips marked with a project's key dimensions, let you transfer sizes without reading a tape.
I can cut a piece of wood in half just by looking at it. It's true, I saw it with my own eyes.
