I purchase this tool while back and it’s fantastic tool. Now it’s time for me to buy some blades, which are not cheap. But since it’s tool that I won’t use that much, I would like to buy the best blades that will last. Searching under Milwaukee and looking at bi-metal I see can buy 3 for about 35.00 or can buy set of 5 different blades in Milwaukee plastic case for 60.00 Are there better blades out there that fit this Milwaukee multi tool or only Milwaukee brand? Maybe Milwaukee blades are best? Looking for advice on blades and maybe sources
