Using this Jokari cable stripper is a breeze. First, pick the right blade pair on the top of the handle according to the cable you're working with. Place the coaxial cable in the stripper and start the stripping process in two steps as needed. The integrated length scale helps you get the perfect stripping length. When dealing with F - connectors, use the 11mm socket wrench on the tool to tighten or open them. Remember, no adjustment is required, so you can just get straight to work. As for maintenance, keep the blades clean after each use to preserve the Titanium - Nitride coating. Store it in a dry place to avoid rusting. And since it's TÜV / GS approved, you can trust it for safe and reliable use.
