One Black Player Edge Again Unit. One Carrying Case with Handle. One Diamond Coated Player Tusk. One Charger. The Edge Again Player Skate Sharpener follows the contour of the original sharpening that the blade currently utilizes. For example, if it was sharpened at 1/2 inch then it will bring the edge back up to 1/2 inch and vice versa for the 3/4 inch and 7/8 inch. This provides the player with the same edge previously used for a quick and easy fix. The four sided patented diamond coated Tusk automatically aligns itself on the skate blade. Simultaneously micro-files four sides of the blade to repair both inner and outer edges in seconds. Simple and easy to use on the fly. Each tusk can last up to thirty pair of skates depending on the severity of the blade's trauma. Easy and safe snap in and out technology makes replacing the tusks a breeze.
