tip: be consistent.
Do you cut on the left side of a pencil mark, on the right side, or down the centre? Did you mark the wood at the left/right or centre of the measurement?
Sometimes it doesn’t matter but, when precision counts, then, it matters – a lot.
Obviously, cutting to the left or right depends on which side I’m keeping, since ignoring the kerf kind of makes the whole fine line thing moot. That aside, there is no real on or beside the line for, say, a point three Pentel pencil or a sharp knife. No?
Ninety-nine percent of what I do is with a point five mechanical pencil. I can’t remember the last time I picked up a regular pencil.
