I refreshed mine using a Dremel tool to carefully restore the tooth profile. And I have spare teeth to use when a refresh no longer works. AND I'm still trying never to pull the vang on through the teeth, only to pull down into the teeth at the end (LOL)
Does anyone know whether it's possible to buy just the jaws of the kicker cleat rather than the whole thing? Mine is slipping a bit and I'd really like to avoid replacing the whole thing when I'm fairly sure it's just wear in the actual clamping parts.
