Hello,

Per the title, can anyone recommend a portable hot knife?  The ropes I am cutting are up to 32mm in diameter, but this has been fine so far by doing in it stages with a normal corded hot knife, so I don't think I need anything really industrial.

Thanks,

Gavin

Gas stove/ blowtorch and an old heavy kitchen knife . This works well on single ropes , larger should not be a problem.

I also have a mini blow torch, ballpoint pen size, about £4 off fleebay , that you can refill with ciggy  lighter gas. That would also make short work of the job, albeit a bit less neatly. It has a 4mm wide, 40mm long flame.

There is also the cavers trick of cutting a nylon climbing rope with a length of thin cord.

Frightening when you first see it done.

Bind both sides of the cut with electrical tape (or whip it, if appropriate) to stop it fraying, cut it with a sharp knife and then seal the ends with a lighter?

Thanks Rick.  I am going to have quite a few to cut so the continued reheating of a knife isn't the best solution for me.

I considered the blow torch/gas soldering iron approach and that would be better for me and have seen a couple of options such as those below, but was interested to know what others use.

I'll save the caver's trick for when in extremis thanks!

Just use an empty beer can like everyone else.
