Extend the life of scrollsaw blades

It always bothered me that most projects require using only the lower half of a scrollsaw blade, meaning "dull" blades get tossed with their upper teeth still sharp. To make use of those teeth, I add a spacer to my saw's cast-iron top. Six ¹⁄₂ " rare-earth magnets mounted flush with the spacer's bottom face hold it securely during cuts. An occasional application of wax to the top of the spacer keeps workpieces moving freely.
