In Speed Skating Blade Maintenance
Compared with the smaller MS42 wedge stone, the MS44 is larger and has a rounded edge. It is better suited for:
- Removing burrs along the entire blade length.
- Honing the sides of long-track and short-track speed skating blades.
- Maintaining a consistent finish while preserving blade geometry. Its larger surface area provides more stability during deburring. (Application guidance based on the stone's shape and sharpening characteristics.)
