For the price, these blades are fine. But the blade thickness is barely more than my splitter's. There's very little carbide; these aren't resharpenable. At the sale price, it wouldn't be worth it anyway.
The blade does give a good clean cut. But being so thin, I would worry that it will flex/distort while cutting.
I was annoyed that my "good deal" was diminished by a California shipping surcharge that was tacked on to the regular shipping price: A surcharge that no other mail order company charges, that I'm aware of.
Anyway, at a good sale price, these blades are worth it, but not at full price.
