I can only tell you that i have spent some weeks looking at differant tests carried out on various rope cutters,the conclusion i came to was that the disc type cutter is better than nothing, but the best type seem to be the "scissor"type cutters.i dont want to mention any trade names for obvious reasons but you could hire one of these for your stag party(hint hint) i just ordered two of them.an outlay that i didnt do lightly,they are quite expensive for something you cant see working!! /forums/images/graemlins/wink.gif
