It seems that over the last 2-3 years the quality of the band saw blades I have been able to buy has decreased dramatically. I can't get more than a month out of a new blade and I used to get several months out of them. I haven't changed what I do, so it has to be the blades that are different. Is anyone else having this problem? Where are you getting good quality blades that work for hardwood, softwood and some baltic birch. Thanks
