It should be able to cut Wantendraht to 10mm. I have tried this with a leftover piece of Hamburger rope factory. It's just that way. In the test, it is important not only to cut 2 centimeters from the end of a piece (while flying the individual cut cardeels one after the other in the room) but \ "in the middle \" to cut, because that is the realistic application case and goes around a lot heavier. \ r \ nWith 10mm wire you need very big hands because you have to open the handles extremely wide to reach the next notch. I can not imagine how to do that with 13mm steel wire. \ R \ nMan needs about 10 - 15 clicks per cut. \ R \ nAfter a cut, your hands hurt and the muscles in your forearm are cramped. In case of emergency, you will certainly develop more power, but cutting every wish and stag of a complete rig in 10mm would be an effort that would not even hold a glass of water and have many bubbles. \ R \ nOn the positive side: \ r \ n- the quality of workmanship looks very good- there is a release with which you can get out of a stuck situation again without throwing away wire and scissors (but I have not tried) - MUCH smaller and MUCH cheaper as a professional device, which is mounted on a workbench stationary. Affordable for normal sailors who normally never use the unit - but not suitable for field-level riggers.
