Review on 🔪 Freud DS0912BW5 Demo Demon Diablo Reciprocating Blade, 9-Inch x 6-12T, 5-Pack for Multiple Uses by Vincent Pavelko

Sharp when new but quickly dulls when you hit anything other than wood. They tear wood, cut cleanly and quickly. I cut window sills from my house by installing modern windows. The blade struck the plaster outside the house several times, and the blade immediately decayed, the teeth rounded. I found that when I was using Dewalt blades they held up a little better against abuse. The saw is primarily intended for demonstration work and of course for cutting many different materials. Either way, if you're just cutting wood these are great blades. Flexible to bend corners easily (e.g. to cut flush with a surface) but stiff enough to cut straight when needed.
