5-Piece DEWALT Oscillating Tool Blades Kit 28.78 + Free Shipping w/ Prime or on orders $35+

I haven't found much difference between "brand" names and ones sold at Amazon for few bucks per blade when it comes to wood blades or metal ones for that matter. The ones for wood cut about the same and all once hit nail are done for. Similar thing applies to metal ones which handle nails somewhat but once hit screw they're done for as well. Exception to this are carbide tipped ones made in Switzerland under brands like Bosch, Diablo and Dremel, they last longest if used properly and handle even soft clay tile like 4x4 sized ones when small cuts need to be done. For long cuts circular saw reciprocating saw or grinder beats multitool speeds and blade wear so I only use for spaces where it's limited access for those. Most blades once teeth are done can still be made into scraper blades with grinder wheel for cutting caulk and adhesives so there's not much point in buying those types even.
