Dianova Ski Edge Tuner – Dual Grit Diamond Sharpener (87° Advanced)

Fine-tune your skis for high-performance riding with the Dianova 87° Ski Edge Tuner. This version is specially designed for advanced and expert skiers who demand a sharper, more aggressive edge angle for maximum grip and precision—especially on hardpack and icy slopes.

Features:

• Coarse diamond side – sets a clean and consistent 87° edge angle, ideal for skiers who want high performance and strong edge bite.

• Fine 300-grit side – removes burrs and polishes the edge for smoother, more controlled turns.

• Dual-grit convenience – tune your skis anywhere, quickly and reliably.

• Durable and lightweight – built with Dianova’s proven diamond whetstone technology.

Who is it for?
The 87° version is ideal for advanced and expert skiers who want maximum precision, edge grip and responsiveness. If you prefer a more stable, forgiving feel, choose the 88° version instead.

Sidewall warning:
Some skis—especially performance models—have plastic sidewall material that protrudes slightly over the steel edge. This must be removed before sharpening.
