Jonard Tools WST-225 Window Shaver. The tool works with cables from 8 to 14 mm in diameter. It is suitable for almost all types of FTTH and microtubing cables you may encounter. Now for the most important thing - its ergonomics. It has a special thermoplastic rubber coated handle. This is not only comfortable to hold, but also allows you to reach cables in corners and hard to reach places. It is very thin and lightweight. This means you can even work on cables that are very close together or right on the surface. The blade is made of high carbon steel. It can easily cut any type of FTTH cable. If the blade gets dull, it's easy to replace - you can buy a set of 25 spare blades separately.
