Which manufacturers blades fit this tool? I'm an electrician and used a factory Genesis blade to cut in a single gang box in cedar siding and also through the 1/2" sheathing: the factory blade looks dull and beat up. Why are all these blades so expensive? You can get Bimetal sawzall blades much cheaper, the design of this blade is not that radically different. Anyway, what fits? Dremel? Bosch? Versatool?
Versa and Bosch yes; not sure about Dremel. It has a 4 pin slippage prevention, looks like you're running the bases, I'd say about 3/4" from 1st to 3rd. I think most of them are becoming pretty interchangeable - they want to sell stuff.
