    Hi, I need to cut a few sections of wire rope which is 10mm in diametre.

    I could rush out and spend money on a giant cable cutter but for a one off job was wondering if a hacksaw with a fine blade will do ? Or will this take to long ?

    A QUALITY fine hacksaw blade will do just great,

    BUT!

    You must wrap the wire with tape first and cut thru the tape to keep it neat.

    A vice also helps the cut quality, necessary for Norseman or other similar terminal ends.

    Having been it the situation of cutting metal lines with out a proper cutter before, I can say that a cut off disk and a Dremal-type tool will also work well.

    Like Fred said, wrap the line with something first!

    Small angle grinder with a thin cutting disk is used for stainless. Provides a neat cut in cable.

    Drill a hole in hardwood. Slot the wood to cross the hole. Slip wire through. Use an angle grinder with a thin (1/16") cutting wheel and cut the wire.

    On trawlers we used a chop saw with an abrasive blade.

    To do a nice job with a neat end, braze or silver solder a few inches where you want to cut, cut with a hacksaw, and the brazing will keep the end neat and "hand-friendly"

    I have always used one of these to cut wire rope. Just hit it with a sledge hammer and it cuts clean.

    Cheers for all the replies. I should have mentioned that I won't have access to electricity. I also don't need a good finish.

    Seems the hacksaw is the way to go.

    No ... the best way to cut multistrand wire rope is w a special shear that cuts at an angle while pulling the wire inwards tward your hand that grips the tool. One of the best tools I've ever bought. I don't know what they are called but I used mine first to cut flying wires for ultralight aircraft I may have gotten mine at an aircraft supply store. It's great to have one for electrical wires .. the largest wires go easily into crimp connectors. For me it's a must have tool.

    I've used a hammer & chisel with a hardened edge on wrapped section of cable. But I don't do this often enough to invest in a special tool.

    I have used a oxy-acetylene welding torch for bicycle brake wires. I had two metal blocks with a small hole drilled in the seam for the wire. Makes an easy cut and the end will never unravel.

    You can get the type of wire cutter that looks like a bolt cutter with a notch. It takes a bit of effort, but they even work underwater.

    Will not this weaken the wire, heating it, or does it not get hot enought when only soldered/brazed?

    You wouldn't be able to splice it if it was soldered.
