PRECISION Sharpening


A consistent radius of hollow, which determines how much the blade bites into the ice.

A perfectly centered groove down the middle of the blade, so that the edges are both the same height.

A uniform removal of steel along the entire length of the blade, so as not to distort and degrade the profile of the blade.

Traditional hand sharpening systems cannot consistently achieve any of these things, much less all of them. ELITE’s automated sharpener does it all, every time.


Unlike all other sharpening machines on the market today, E-S4 automated skate sharpener’s revolutionary technology maintains the integrity of the blade profile and its performance characteristics from one sharpening to the next, for the life of the blade.

The E-S4 uses high-tech industrial controllers and precision digital drives to automatically control the speed and pressure of the sharpening. The ELITE automated skate sharpener protects the profile of the blade with exact precision. That means we preserve the performance characteristics of your blades in way which is impossible to achieve with any other sharpening system.

Prior to sharpening, the E-S4 first scans and registers the blade shape. Once the sharpening begins, the system detects changes in blade angle and position at every millimeter and adjusts speed and pressure to remove exactly the same amount of material along the length of the blade. In real time, the E-S4 uses sophisticated algorithms to react to hundreds of data points in order to accurately reproduce the existing blade profile throughout the sharpening process.

Steel wheels

Unlike traditional resin-stone sharpening wheels in common use, ELITE wheels are made of an advanced steel alloy with a synthetic diamond coating. Our wheels are machined to aeronautic standards to create the most precise radius hollows. The steel core maintains dimensional accuracy and stability, while the coating provides superior durability and cutting power.



In traditional sharpening systems, the familiar sparks flying off the blade are in fact fragments of the resin-stone grinding wheel disintegrating and burning as it comes into contact with the higher-density steel blade. With each sharpening pass, the integrity of the resin wheel is degraded, leading to inconsistent hollows and ultimately compromised results.

By contrast, ELITE’s synthetic diamond coated wheels are harder than steel blades, and not subject to the performance degradation typical of resin-stone wheels. The durability and precision of the ELITE diamond coated wheels represents a dramatic advancement in the science of skate blade performance. They maintain their shape perfectly for the life of the wheel.


Quick and Easy

As well, with the E-S4 there is never a need to “dress” the wheel. Operators simply select the desired radius wheels and installation is quick and easy. Each ELITE wheel is factory-formed to hollow radiuses ranging from ¼” to 1¼”.


Clean Technology

The E-S4 does not produce the offensive resin-stone debris and airborne particles typical of traditional sharpeners’ work environment. The small amount of residual material produced by the E-S4 is managed by an integrated vacuum system.

Inaccurate blade-to-wheel positioning can result in a serious compromise of blade performance. Even a few thousandths of an inch offset can result in a perceptible difference in blade edges.

Through engineering innovation, ELITE has developed a self-centering clamp system that ensures the exact center of the blade meets the exact apex of the grinding wheel, every time.

The E-S4 clamping mechanism uses two symmetrical plates to center the blade over the wheel. The E-S4 ensures the blade is fixed into the optimal position regardless of variations in blade width.

The accuracy of the self-centering clamping mechanism, combined with the precision of the steel alloy wheels, means the E-S4 automated skate sharpener delivers a perfect hollow every time.

The E-S4 is also by far the most efficient system available today. Sharpening two skates at a time, the hands-free system quickly puts a perfect edge on the blades while allowing the operator to perform other tasks. Sharpening times can vary, depending, for example, on how damaged a blade is, but on average the E-S4 can sharpen a pair of skates in approximately two minutes. For machine operators, this efficiency adds up to huge time savings.

The E-S4 is now available in custom team colours and logos, so you can rock the look in your dressing room. Send us your pantone colours and logo assets and we’ll have them custom wrapped onto your machine.
