Brynäs IF are one of Sweden’s best ice hockey teams. We discover how combining the latest knife blade steel and the best boot innovations keep them ahead of the competition
Defenceman Ryan Gunderson steps out onto the empty ice rink, the blades of his skates meet the glistening ice and he’s off in a flash of steel and snow. Here, the cutting-edge kit the players choose to utilise, right down to the steel of their blades, can make a crucial difference to their performance and career.
We’re at Gavlerinken Arena in central Sweden on an icy January day. The vast 8,000-seat arena is home to Brynäs IF, one of the most successful and best-loved teams in the Swedish Hockey League (SHL). Ice hockey vies with football for the position of most popular national sport in Sweden and the ‘Tre Kronor’ national team took home silver at the last Winter Olympics.
Gunderson steps off the ice and notices the blades on teammate Daniel Paille’s Bauer skates. “You still using the LS2s?,” he asks. Gunderson, along with around 80 percent of players in the Bauer teams, has upgraded to LS4 blades, which use one of the Sandvik SanEdge® range of knife steels: Sandvik 14C28N. Formulated by Swedish steel company Sandvik, this hardened knife steel resists blows better and requires less frequent sharpening.
“On this steel you can go a whole game or maybe more without resharpening”
Mattias Pettersson, equipment manager for Brynäs and a former goalkeeper for the team, explains how a harder steel affects his job. “Other brands have a softer steel and sometimes need resharpening three to five times during a game. On this steel you can go a whole game or maybe more without resharpening. So it makes my job a lot easier.”
The new blades also have a removable and higher profile (their shape), allowing players’ boots to achieve a lower angle on the ice while turning without actually hitting it. Back in the locker room, Paille, a left winger from Canada, former Stanley Cup winner and one of Brynäs’ most experienced players, shows us the customised lift he’s had attached to the back of his blade holder to achieve the same effect and help him lean slightly further forward.
“Mattias has explained to me that the LS4s might help with that so I won’t need the lift anymore,” says Paille. “It’s just something I’ve stuck with my whole career so I’ve stayed with it, but I think the new blades are something I’ll try in the off season.”
At this level, players expect the very best from their equipment and all have their personal preferences when it comes to frequency of sharpening, blade profiles and sharpness of edge. But while some, like Paille, are happy to stick with what’s always worked for them, others are keen to embrace the latest technological advancements.
Philadelphia-born Gunderson, who began skating when he was three, says, “I try to keep up with the newest pair every year and if something better comes out I switch to it. I’m constantly changing things on my steels and different ways I can perform better.” Over the last few years he’s noticed more steel in the blades, a more powerful push, added height and better durability.
“I’m constantly changing things on my steels and different ways I can perform better.”
So what exactly is it that makes this steel so much harder than previous steels? Björn Mogard, Global Product Manager at Sandvik explains: “Sandvik SanEdge® 14C28N was originally developed for knife applications. Compared to standard steel grade Sandvik SanEdge®12C27, used for both knives and skate blades, a higher final hardness after hardening can be achieved with 14C28N. The result gives a better edge wear resistance.”
The steel, which is manufactured in the town of Sandviken, just 23 km (14 miles) from Gavlerinken Arena, is the result of a successful working partnership between leading ice hockey manufacturers Bauer and Sandvik. “We chose Sandvik steel because our advanced research shows that this particular material under a microscopic analysis has properties that allow for improved edge retention and durability,” agrees Robin Öhman, sales representative for Bauer in Scandinavia.
Canadian-based Bauer have long been at the cutting edge of skating technology. “We were the first company, in 1933, to attach the runner and holder to the boot,” says Öhman, “and two years ago we introduced a removable clip on the holder for the steel, allowing it to be changed quickly and easily for re-sharpening or replacement.”
What amateur skaters may not know is that pro skate blades are sharpened by grinding a concave hollow through the centre of the blade lengthwise. This creates two sharp edges per blade and the depth of the hollow between the two edges is what determines how sharp the edge feels. The size and weight of the player, the blade profile he chooses, the conditions of the ice – as well the hardness of the blade steel – all these factors affect how a player chooses to have his or her skates sharpened.
For instance, in the US, the ice is generally considered to be harder, so players choose a sharper edge. Paille has softened his edge since coming to Europe.
Mattias demonstrates on his state-of-the-art automatic sharpening machine. “A deeper hollow will give you more ‘grip’ on the ice, so your blade will feel sharper and will hold the edges better. A shallower hollow will have less grip but more glide and easier stops and starts.” Where previously his job involved hand-grinding an edge in a clamp, he now has a machine that can automatically carve out different base profiles for individual player preferences, making his job easier physically but more technically demanding.
“Sandvik steel is a combination of the hardest steel we’ve ever had and the most efficient steel regarding how good an edge you can get when sharpening,” says Öhman.
So where do we go from here?
Öhman confirms that Bauer’s R and D department “are not sleeping” and they’ll continue working with Sandvik steel to find new ways to keep elite hockey players skating harder, faster and for longer. And as for those of us still wobbling around the local rink – well, we might just find paying a little more attention to our skates and steels could bring us one step closer to the skating style and skills of the Brynäs boys.
