Well gentlemen I did some studying about 12 " saw blades and it takes some thought but it seems that the good brands are Diablo which is expensive CMT which is very expensive (DaninVan where would you get them at a lower price than Amazon) and Danman 1957 I live in Brossard and I don't know of any place to sharpen saw blades.
I'll have to go around tool places to see what they have,you can't see what they really have on line.
If there is anything you think of bring it here and I'll keep an eye on this thread. The blade in the saw is an exchange a blade EAB for short
Thank you guys
Stuart
