Profiling is not just about sharpness; it is about adjusting the "rocker" or the shape of the blade. On our professional ProSharp AS 2001 machine, we can modify the radius of the blade's contact with the ice, which fundamentally affects your stability and agility. Profiling allows you to set a slight forward pitch for more aggressive starts or a centered balance for better stability for defensemen. We use professional templates used by NHL players to ensure the blade perfectly matches your weight and stance.
You can learn more about the benefits and technology of profiling in our dedicated article here.
The primary advantage of Sparx technology is absolute consistency. If you have your blades sharpened at our Hradec Králové store to a 19.1 mm radius, you will receive the exact same result every single time you return. This is crucial for muscle memory and confidence on the ice – you no longer have to "break in" your skates after every sharpening or get used to a different edge angle. Furthermore, Sparx's precision saves blade material, significantly extending the life of high-end steel such as Bauer LS Pulse TI or CCM Step Steel.
Thanks to a wide range of Grinding Rings, you will find the exact hollow that suits your game. You can choose from these specific variants:
| Hollow Radius (mm) | Characteristics and Recommendations |
| 6.35 mm – 11.1 mm | Extremely deep hollows for maximum control (ideal for goalies). |
| 12.7 mm – 15.9 mm | Deep hollows for aggressive forwards and quick directional changes. |
| 17.5 mm – 20.6 mm | Standard for most players (including the popular 19.1 mm). Balance between glide and edge. |
| 22.2 mm – 28.6 mm | Shallower hollows for power skaters and defensemen requiring high speed. |
| 31.8 mm – 44 mm | Very flat hollows for elite skaters preferring minimal ice resistance. |
Our specialists in Hradec Králové check edge alignment and the overall condition of the skate during every service. If you want to enjoy the same quality at home, we offer a complete range of replacement rings in all millimeter variants directly on our e-shop.
