Spyder Products' new Double-Sided Jig Saw Blade is an attachment for reciprocating saw that has cross-ground teeth for a slim design. Its unique shaft form permits tight radius cuts and 90˚ turns. The Double-Sided Jig Saw Blade comes in a woodworking blade and a multi-surface blade. The woodworking blade has longer teeth on both sides of the blade, allowing the user to turn the blade without limitations: it's cutting while it's turning. The Double-Sided Jig Saw Blade is made in Germany of chrome vanadium steel. A set of two 4" woodworking blades sells for $6.97, while a combination pack (one woodworking blade and one multi-surface blade) is priced at $5.97.
