Frank, I'm not sure I have a good answer for you, but that has never stopped me
I think that bandsaw blades are just something that you have to consider as a consumable, that being said, it really sounds like you are going through them at a much too fast pace.........
One thing about the carbide tipped ones is they do last a long time, compared to the normal ones, but 5 times.........? Dunno.....
Using Steve Russell's protocol, I got a lot more use out of the carbide tipped blades on Big Blue, a LOT more, I keep one for doing super thin resaw, and the other for hacking up bowl blanks. The bowl blank one I've resharpened by hand, using the Dremel about 4 times now, still cuts very well, but not as well as the one that was professionally sharpened.
Like I said, dunno if this helps or not, but I thought I'd give you my take.
