Choosing the Right Edge: Your Guide to Blademaster Grinding Wheels

If you’ve ever stepped onto the ice and felt like you were sliding on butter or, conversely, felt like your skates were "stuck" in the ice, you know that a skate sharpening can make or break your game. But for those behind the machine, the real magic happens long before the skate touches the ice. It starts with choosing the right grinding wheel.

We’ve put together this guide to help you understand the "why" and "how" behind the industry's most trusted wheels.

The Essentials: What Makes a Good Sharpen?

A professional-quality sharpen is defined by three things:

1. Even Edge Height: Both the inside and outside edges must be level.

2. Sharpness: Clean edges that "bite" into the ice.

3. Finish: A smooth, shiny surface with no burrs or chatter marks.

To achieve this, the choice of grinding wheel is your most important variable.

Which Blademaster Wheel Should You Choose?

Blademaster offers a variety of 8-inch finishing wheels tailored to different steel types and operator preferences. Here is the breakdown of the lineup:

1. The Industry Standard: Purple (8VBP)

If you’ve walked into a pro shop, you’ve likely seen this wheel. It is Blademaster’s best-seller for a reason.

• Best for: All-around high-performance sharpening. Used by the hockey professionals, leagues, pro shops and home users around the world.

• Why it wins: It has the best form retention in the industry. This means it holds its shape (the radius you dressed into it) longer than other wheels, saving you money on dressing diamonds and ensuring a more consistent sharpen across multiple pairs.

2. The Cool-Cutter: Yellow (8AS)

Aerospace-grade technology meets the ice rink.

• Best for: Players who are sensitive about edge retention.

• Why it wins: It grinds exceptionally cool. Requires less cutting pressure for optimal finish.

3. The Specialized Finisher: Pink (88R)

Not every blade is a standard hockey runner.

• Best for: Figure skates and goalie skates.

• Why it wins: It features a finer, uniform grit and a closed structure. The 88R grinding wheel is excellent for figure skate and goalie skate sharpening. The steel used on figure skates and goalie skates is harder than hockey skates. The 88R has a finer grit, meaning it will react better to harder steels than other ceramic-based wheels. You'll remove more material using the 88R without burning the steel and will leave a better finish on the wheel.

4. The Multi-Tasker: Ruby Red (8MXRUBY)

With the rise of carbon-coated and "black" steel, your wheel needs to be tougher.

• Best for: Shops that see a mix of carbon and stainless steel.

• Why it wins: It contains a high chromium content, making it aggressive enough for hard carbon steel but refined enough for a perfect finish on standard stainless.

Frequently Asked Questions - Pro-Tips

How often should I dress the wheel? Always dress the wheel when changing the Radius of Hollow (RoH) or if you notice the finish becoming dull. 

Which direction should I sharpen? While some debate exists, Blademaster always recommends sharpening from heel-to-toe. This ensures consistency with our contouring (profiling) operations, where the operator must move with the rotation of the wheel.

What is "Gusto Glide" and do I need it? Think of Gusto Glide as the "secret sauce." It’s a synthetic lubricant applied to the blade edge during the final pass. It allows for a cooler, cleaner sharpen and a mirror-like finish by preventing the wheel from "loading up" with metal shavings.

How many pairs of skates can I sharpen? That answer depends on the wheel selected and how frequently it's dressed. Approximately 200 pairs on average is a conservative answer for all our wheels. However to reiterate, this depends on the wheel selected and how frequently it's dressed.

When is it time to replace the wheel? Depends on whether you have a variable speed finishing head. On a Variable speed machine - customers with machines with variable speed finishing heads can use the wheel down to the blotter and still achieve the same cutting pressure and surface finish with a 5” wheel as they do with an 8” wheel.  Without variable speed machine - customers can use the wheel down to the blotter however it will not cut as quickly. This means more passes and the finish is not going to be as nice as on an 8” wheel. Typically customers without variable speed finishing heads will stop using a wheel once it gets down to the 6” mark.  

Can you buy grinding wheels in bulk or just individually? Yes, we sell wheels individually and by the box also. There are 6 wheels in a box. 

What is the best grinding wheel for hockey skate sharpening? Popular grinding wheels for hockey skate sharpening are 8VBP / 8MXRUBY / 8AS / 8GC. 8VBP tends to be the most popular. However it really does come down to personal choice.

Do you carry replacement parts for where the grinding wheel sits on? The wheel nut that holds it in place? We do carry replacement parts - please contact customer service at guspro@guspro.com to discuss further.

What grinding wheel provides the absolute best finish? Our 8AS Grinding Wheel provides the absolute best finish and optimal edge retention.

The Bottom Line

Whether you are a professional equipment manager for an NHL team or a "hockey dad" sharpening in the garage, your wheel choice dictates your results. If you want the most reliable, cost-effective performance, start with the 8VBP Purple wheel. If you’re working with specialty steel or goalie blades, keep a 8MXRUBY Ruby Red or 88R Pink wheel on standby.
