The Step Blacksteel Speedblade +4.0 Runners are some of the hardest steel runners on the market. Carbon nanoparticles coat the outer layer providing an extremely hard edge. This produces incredible bite and control on every turn and stop, as well as prevents burrs after sharpening.

Not only that, but this highly polished finish outperforms the competition in the Coefficient of Friction performance test. This test measures the amount of force required to make a skater glide, and the results of Step Blacksteel were 50% less than comparative steel! This means you'll use less force, gain more speed, and save more energy shift after shift!

Step's Blacksteel is also one of the best runners at withstanding nicks from bangs and impacts against equipment and other objects. All of Step's blades are built with a higher profile which gives hockey players an even deeper turn with more precision, and longer sharpening life.
