The sharp thing goes through cables and cases like butter, the cut edges are clean because of the backlash-free knife and not kinked. The Crimp function for ferrules work, but because of the position in the middle of pliers, it is a bit uncomfortable, nachzucrimpen an assembled already at the switch or derailleur train for example. If you do that often, a Aderendhülsenzange would be easier here. With the tumbler, the head body remains small and handy in the tool cabinet. Very comfortable and handy grips.
Pleasantly surprised I was about the use in our garden: Every now and then thin and medium fence wires must be cut to length. Side cutters and cable cutters (for copper cables) are much too sensitive, but this steel wire cutter goes effortlessly and without nicks through the fence wires. A joy this tool.
