November 2, 2015 – Spyder Tools says it has expanded its line of rounded tip, double-edged blades with a “longer-lasting, cobalt-strengthened version”. Spyder says its 3×3 double-sided reciprocating saw blades allow uses to plunge cut and make multi-directional cuts, even through metal.

The new design featured additional 8% cobalt, the company says.

Manufactured in Germany, the blades come in multiple tooth configurations. They are available at Lowe’s.
