I used a circular saw to cut an old heavy stair trainer that was too heavy and old to move or sell. It took me about half an hour and I went through 3 of these blades.

I've seen them explode due to the side force generated when cutting long corners of the steel sheet. They are very loud but leave a very clean cut. They are attached to a base saw I bought from Home Depot. Wear glasses!
