Somehow we missed this when it came out a few months ago in Fine Homebuilding Magazine. It is a very nice detail comparison of 15 major demo blades for wood. Looking at price, TPI, cut speed, cuts, flexibility, etc it really goes deep with each blade. It was pointed out to us while having a discussion about metal cutting blades in Garage Journal forum which is obviously a different kind of blade but though it was a good read anyway. For the full story check it out here at Torture Test – Demolition Blades

You can also purchase a wide variety of demolition and other Sawzall / Reciprocating Blades from the fine people at Ohio Power Tool.
