I agree, and normally, I'd be returning it and switching brands, but I'm happy with all my other ryobi one system stuff, so I have several batteries.
Plus so far I do like the jig saw itself, so as long as I can trust the Bosch (or other available t shank) blades, I'll settle for merely sending ryobi an angry letter. But I'd really like to know the Bosch blades are safe when locked only as far as that 45 degree position.
By the way, any one have an opinion of Rigid blades? They appear to have the same ryobi universal design.
