The Staybent Speed Skate Frame Top Stops are designed to be used with the Stay Bent Speedskate Sharpening Jig.
Blades can have small differences in height, and simply dropping them into your jig can cause unwanted angling to your edges, when you use your sharpening stone. Prevent this by using the Stay Bent Top Stops. Mount these top stops onto your jig before sharpening, then pull your blades up to the stops. This will keep your blades level, giving you a perfect edge every time.
