This great statistic accompanied Bosch’s news of their special 60th-anniversary jigsaw blade case: since 1947, they’ve sold 4 billion blades, enough to circle the earth 10 times.

Does that not conjure an image of our planet, seen from space, as a kind of serrated stegosaurus?

You can add another dozen to that number with the purchase of their limited-edition woodworker’s set, which has the good-looking aluminum case seen above, and magnetic blade storage within. visit on the jump to see what you get.

The T101Bs, far left, are for straight, fine cuts, and plunge cuts in all woods.

The T101AOs, next from left, cut curves. With these, turn off the orbital

T101Ds are pretty similar to the T101Bs, but with fewer teeth per inch for a coarser cut.

The right side starts with a pair of T119BOs, which manufacture curved cuts in soft wood, OSB, or plywood.

The T144DP and the T244D compose quick cuts in all woods; the first cuts straight and the skinnier one does curves.

And the T234X blade is a Progressor, which means the big teeth at the tip cut coarsely. The teeth get  "progressively" finer as they get closer to the saw, so you can cut thinner materials more cleanly.

So there. Now, perhaps, you’ll be less puzzled by jigsaws.
