I like the think I am frugal. I look for the best buys, and stock up when I see a good sale if I can. I do use Harbor Freight blades and am good with that. If I get a bad one, which has been rare, I just use that blade to cut Christmas, birthday paper and other crafty items with. (a tip from my neighbor).You would be surprised at the life still in a blade.
I like good quality material and don't compromise on that. I find quality in many things that doesn't have to cost a fortune, like an old Singer for instance. It is all good!
