An absolutely wonderful tool!!!
Had to widen a door opening to install a wider door (exterior). Found dry rot (sill plates, sitting on concrete footing, under the floor joists). These sills, along with the rotten 'tails' of the floor joists would have been difficult to cut out with any other tool. I guess I could have used a chisel if there was enough room to swing a hammer. Got out my HF wonder tool and sliced through 3 joists and 2 plates in less than a minute.
A MUST HAVE TOOL!!! (whatever brand)
