Hello, I didn't want to hijack papadan's post, so I am here with some odd size blades. Porter Cable seemed to be the king of odd sized saws & blades!! 4-1/2, 6-1/4, 6-3/4, 7, 7-1/2, 8, 8-1/4, and a 10-1/4. I believe I also have a 6-3/4" saw here somewhere. The 6-1/2 in the photo is a Roc-Edge, the other 2 are Porter Cable. Regards, Lou
