I recently purchased the Ryobi P523 Jigsaw. I was going to use some Bosch T-shank scroll blades that I had used in my old Ryobi jigsaw on a project with my new jigsaw. Well, the T-shank Bosch blades will not fit in the new jigsaw and the specs list: For use with T-shank jig saw blades or Ryobi universal shank jig saw blades.The lock collar for the blade will not quite lock into place. The shank above the T is just a bit longer than the Ryobi blades I have. So, I go to my local Home Depot in Raleigh and well, they don't even sell Ryobi jigsaw blades. Really?? 99% of what they have is Bosch and then some knock off brand. Has anyone else had this problem? It seems to me that Ryobi made a boo boo with this and why does Home Depot not carry Ryobi jigsaw blades in the store? I like the jigsaw and it cuts great with the standard wood blade I have but I'm probably going to return this thing unless someone know's something I don't. I'm not going to order and wait on blades every time I need one.
