Description
The V4 is made from a single piece of durable and lightweight aluminum. In the early 1990s (before the clap skate), Falco Zandstra became World Champion on a similar Raps product (the flyer). The hardness (the harder, the less often you need to sharpen) is 60 HrC. In terms of quality, weight and hardness, there is no comparable skate blade on the market.
The mounting distance is fixed per iron. There are options to file the hole slightly (half a cm) or 1 or 2 further forward in the front pot.
