The only thing that worked on an oak stump

After an encroaching oak tree was cut down I had the task of removing the stump. After dulling chainsaw and regular saw blades and being unsuccessful with an axe, I bought the 5T demolition blade. It kept cutting even after hitting rocks and pebbles in the stump/roots of the tree. I only had to stop to let the electric handsaw cool down before continuing. I highly recommend it if you're going to be hitting anything besides wood.

Roof Removal.

It worked great and I'd certainly recommend to anyone removing roofing!!!

Best Blade Ever for Renovating Decks

When the previous home owners had laid the deck, either no spacing or very little spacing was put between the boards. After years of pine needles, leaves, dirt and everything that got trapped I was trying to determine the best way to proceed. I welded to recipro blades together and it "worked" but felt as though you had used a jack hammer. Saw a review of the BigBlue "Nasty" Demo blade and thought what can I lose for that price. Holy Toledo!!!! Nothing stops this blade, dirt, wood, nails, etc, etc. Deck boards now have nearly perfect spacing, didn't use a straight edge, just took my time to follow the "groove". Blade didn't kick, stall, anything - like cutting butter. BigBlue Demo blade is the best.

Awesome blade!

This blade is amazing! It cut through 3 layers of shingles and 1/2 inch plywood like crazy and turned what would have otherwise been a very difficult job, in to a fairly easy task. I would recommend this blade to anyone who is looking to demo a roof.
