Andy has agood suggestion on just buying vicegrips. I have a pair of the smallest four-inch ones, and they are very durable. I noticed that many people are suggesting the Micra, but personally I don't like this tool because all it really is is a pair of scissors, and who needs that if you have a knife? I have used the SOG Crossgrip (http://www.sogknives.com/crsgrip.htm) for years and I am very happy with it. It is about the same size as a Micra, but it has pliers and best of all, SOG's amazing design which incorporates compund leverage, making the jaws pinch much harder than you have to. I would highly recommend this tool.
