I bought these (attached to a pair of boots) with the assurance that they were 9.5" blades, but to my surprise when I removed them from the boots, they are 9.75", so I can't use them. I'm so disappointed!
I was told they have only been sharpened twice, and they were used for about 9 months. The aluminum chassis above the SS runners is fairly chewed from toe hits in jumps, and they will need to be sharpened, but they have plenty of sharpening left.
