I switched to a different blade immediately, so the actual usage time was less than a year. * Used 1-2 times a week * For adult beginner skaters, with jumps up to single jumps, so the durability is sufficient, and there is still plenty of sharpening life left (please refer to the images). - Brand: CORONATION ACE - Brand: JOHN WILSON - Type: Ice skate blade - Size: 10 1/4 inches Thank you for viewing.
