Sawing frequency and material has a lot to do with it, and I may or may not do more sawing than you, but the preference of most folks I hear from is for high quality bi-metal HSS blades, such as Starret and Lennox. My local saw & sawmill supply shop was a great source (per the above comment) but was forced out of business a few years ago by urban "upscaling." That's the punishment they get for staying in business for 100 years in the same location. (The Hilton didn't want a 100 year old sawmmill supply next door.) So I decided to begin making my own blades and went to eBay and took a chance on a 100ft roll of 5/8"x.025"x18T carbon steel Eclipse bandsaw stock (Eclipse was sort of a British Starrett) for a very low price. First of all 5/8" was oversized for my saw, but it did fit, and ran well, so for the price I would live with it. My thinking was, let's see how it works out using a very low cost-per-blade (<$2 ea) carbon stock vs. the correct good HSS blade.
My results were that this blade stock does OK, with certain drawbacks. The drawbacks of carbon blade stock as I see them are:
CS is more susceptable to overheating and softening when silver-soldering the joint, which is a tapered lap joint, not butted.
Broken teeth tend to "domino" so that one broken tooth can eventually lead to a whole section of adjacent teeth breaking.
The first teeth to go are around the lap joint which have been unavoidably annealed to some degree.
As the blade wears and dulls it tends to favor one side or the other resulting in the cut drifting toward the sharper side.
Fresh blades cut great in copper, brass, bronze, ally, and cast iron. They cut OK in mild steels. They wear quickly in hard alloys and most SS.
I figure I use 3X more CS blades than I would HSS.
ALL of these comments are also true of HSS, eventually, but things just wear faster with CS. The problem with this for me is that the low initial cost of the blade material has not been a good tradeoff for the extra time spent cutting, dressing, soldering, and grinding the joints for more blades than I would otherwise use. Had I it to do over again I would still make my own blades, it's very convenient to be able to have a new blade NOW, but next time I will go with a good HSS bi-metal blade stock.
