Flem. I just use a 1/2” low TPI wood blade (anything you would use to rip wood). I use my old blades as the Fiberglass will ruin a blade, but they still will cut bows. I usually cut my limbs to rough size and then take them to the belt grinder. I think it is faster and much cleaner in the shop than grinding to shape
This last bandsaw blade I used, I have 5 bows worth of cuts on it and I can still use it. I find the regular bands usually last 5+ bows before they are completely worthless or break.
I heard there are carbide tipped blades which will significantly outlast a regular wood blades, but using my old woodworking blades is cheap and effective.
