Easy-Plunge Recip Blade. The Spyder Bore-Blade looks more like a miniature chain saw than a typical reciprocating saw blade. Its rounded nose is designed to make plunge cuts easier and smoother. Double cutting edges allow the user to cut forward or backward without having to reverse the blade. According to the maker, the 1.23-mm-thick bimetal blade can cut pipes, nails, and sheet metal as well as wood. It comes in 6-, 8-, and 10-inch sizes; the 6-incher costs $10.
