I know that for any woodworker it is impossible to have every tool in the book but there are some things that one just cannot do without, such is the jigsaw. Invented 60 years ago by a Swiss man who converted his wife's sewing machine to cut wood by grinding down and installing a piece of hacksaw blade into the machine the jigsaw has gone on to be one of the most popular power tools in the average workshop, domestic or professional. I have a couple which I use a lot especially when cutting curved components such as sheet ply which is too large to work on the band-saw but it is very important to use the correct blade for the job. The picture shows some cuts that I made in half inch thick marine ply and as you can see they are perfect straight from the saw. The blades that I use for this type of cut is the Bosch 101AO, which have needle teeth not too dissimilar to those found on Japanese pull saws. With the pendulum action turned off they really are the nuts with almost no tear out even when cutting against the grain on the face laminate. A quick trawl of the internet shows these blades can be had for around $8 for a pack of five which considering how little cleaning up you have to do once you have cut out the component is money well spent.
