As you know I bought the Bauer brand saw. I also bought #18 band saw blades at HF also. Yes I know they are the bottom of the barrel but they are not making a scratch in my 3/16 unhardened 1090 steel. I did see Ed recommended cobalt but I was hoping at least I could get started on a knife with these cheap blades. I thought I could at least cut one blade with it. It did cut 1/4 inch aluminum table I built for it. Anybody use the Bauer brand blades and if so which number?
