Have the Felco medium size cutters, the ones for up to 3/8" wire IIRC. Have used it to cut mostly 9/32" and it is not easy. Added a couple of pipe extenders to the handles so there was the leverage to cut that wire. Cutting 3/8", only did it once, was very very hard to do on a stationary dock
even with the handle extenders. Suppose that the adrenaline rush cutting rigging
in a dismasting
would make the job easier but take Felco's max size range with a large grain of salt
Think I'd go with battery
powered angle grinder, if there is such a thing, with a cut off, not grinding, wheel
for an emergency cutter
. Also would be a good tool for general wire cutting and rigging
work. The big problem with a battery
powered tool is keeping it dry and functioning while you are cutting away rigging in anger and the inevitable battery failure. Have had the Felco cutters for 40 years and they still work as well as the day I bought them, rain or shine.
Installed the Norseman terminals on our Westsail dry. They were still good after more than 10 years. Have no long term experience with terminals installed with caulking. The manufacturer recommends it so now defer to their experience. Thought it would made changing the wire out a problem but it's been relatively easy to remove the terminals when LifeCaulk was used for caulking.
