The shape of perfection The secret of the extraordinary ability of XProfile lies in its design: an x-shaped section with x-advantages. It is responsible for the point being self-sharpening because the wear occurs on all four blades of the chisel. At the same time the unique geometry reduces the formation of dust cushions thereby providing better and faster penetration of the material. Another bonus: minimized risk of overheating. The special strengths of XProfile come into their own when high levels of dust are involved e.g. when working with concrete, gypsum, clay, chalk.
