These are band saw blades and 160 or so grain,they sharpen up great and pretty easy.Kenneth
at first they were way off but after working with them I got them pretty close.My bows are all
in the low 50's at 26 and around 60 lb spine weight cut at about 29 inches seem to shoot the
best.I had several a lot heaver than that so just for a test I done some light scraping on them in the middle 2/3 and it brought them right in.I don't know if you are supposed to do that but I did and it seemed to work fine.Now they all shoot good.
