Sharpening

[mark w]

Axe can be the best choice especially if you are on site - you stand the board end-down on the floor, held with one hand and use axe in the other. Easier in workshop too - you have to lay a board down in order to use a jig saw and clamp it. Axe also easy to undercut for easier fitting, etc.
Free hand tool usage (and freehand sharpening!) are very under rated.

I couldn't get on with an axe for cutting to a scribed line, my brother on the other hand was really good at it.I didn't need a clamp when using a jigsaw, also the base was tilted for the undercut so it was quite easy. Each to there own Jacob, both tools are good in the right hands.
