How to clear your line of sawdust without blowing yourself dizzy. Plus, learn how to mark accurate 90° and 45° lines without a square.
About 35 years ago I was using a handsaw in what I considered the usual method: Cut, blow the sawdust off my pencil line and then cut some more.
The foreman on the job was watching me work and he came over and stopped me. He said he was told many years ago of a way to cut with a handsaw so you didn’t have to blow the dust off the line. He didn’t show me the method because he said he’d never been able to do it himself, but the basic idea was as follows:
You cut on the down-stroke and lift the saw a bit out of the kerf on the up-stroke. By developing this slightly orbital stroke, most of the dust falls on the floor.
After practicing this orbital stroke for a while I noticed something else that my foreman had not mentioned. The small amount of dust left on the surface of the work was pulled away from the cut line, like the wake of a boat in water.
This is really neat to see, and I think it is caused by the regular, rhythmic vibration within the workpiece that is created by this type of saw stroke. Try it – you will like it!
At one time there was a product available that was designed to blow dust away with a hand saw called “Clear-Line.” It was attached to the bottom of the saw handle and directed a puff of air onto the surface of the board with each stroke of the saw.
As a tool collector for the past 35 years, I have looked at thousands of handsaws and have never seen one with a Clear-Line unit attached to it. Could it be that most woodworkers of the time knew how to cut without the need to purchase such a device?
Bonus: Saw as a Square
One more neat (and sometimes useful) trick is to use a saw as a square. This is done by placing the saw in a vertical position across the face of a board. Observe the reflection of the board in the side of the saw blade. When the reflected edge is straight and in line with the edge of the board, the saw blade is set at 90° to the board’s edge.
If you want to mark a 45° angle, move the saw until you see a 90° corner formed by the reflection and the edge of the board.
