I order my blades from Amazon, and have been happy with them. I don’t remember the brand (it was not a name brand), but the price was much better than Joann’s with a coupon. When I was at MQX New England last year, one of the vendors was using a titanium blade and said they lasted a long time. I didn’t buy any at the time and have not seen any. Of course I haven’t looked too hard, since I still have blades.
