The legendary Bont Platinum blade is back. Made with Böhler K390 powder metal tool steel which is slow ground to produce a perfectly straight piece of steel. The powder metal structure is very fine which gives exceptional gliding properties. Able to hold its edge up to 8 times longer than normal steel blades the tube has the highest bend retention of any blade on the market.Specifications

TEAM TESTINGOur Pro Team skaters are some of the best in the World and love to give us constant feedback. From the little things like the placement of the buckle to trialing the latest materials, they are helping Bont create products that not only look good but perform at the elite level.
CONSISTENCYConsistency has been the focus when creating our blades. Machining time is expensive and blade manufacturers grind the steel in batches at high speeds to reduce costs. This results in the steel warping due to the high temperature of the grinding stone grinding the steel. Our aim for the GT3 and the Platinum was to make every blade the same so we purchased the best grinding stones from Germany and we slowly grind one set of steel blades at a time. This is an extremely slow process with higher costs but the result is steel that has no warping. All skaters, not just Olympians, should enjoy perfect blades. However, we didn't stop with the grinding. We looked at the other aspects of making the blade even more perfect. We developed a new stronger glue that allowed us to reduce the tube slot width by 0.1mm. The tube slot needs a certain amount of room for the glue on either side of the blade. The greater the gap, the more chance the steel has to warp while the glue sets. By reducing this gap, we improved the consistency of the straightness of the blade after gluing. Lastly, we invested heavily in jigs. Each blade is clamped in 9 locations while it sets and we let the blades set for 14 hours until the glue has fully cured. This means that we can only make a few sets of blades per day, but each set is perfect.
Aluminum tubes do not like to be bent. They always spring back to the straight position. To solve this problem, we have two solutions:
- We make the tube out of an aluminum that is more likely to stay bent than other brands of blades.
- We cut the slot for the steel blade in the aluminum tube on a slight bend. The tube is straight but the steel blade is already on a slight curve. This curve is slight and you will still need to bend the blade more to get the optimum bend to suit your radius. However, you now only need to bend the aluminum tube a very small amount to get your optimum bend. This small amount of tube bending is not enough to stress the tube and the result is a blade that holds it's bend for a much longer period. Some skaters may never need to re-bend their blades.
