The Coleman 12 in 1 scissors looks to be a good addition to your camp equipment. Functions include scissor, knife, screwdriver, magnet, can opener, wrench, fish scaler, nut cracker, jar wrench, wire cutter, wire stripper and bottle opener.
In a world populated by $100 multi-tools, the Coleman is a minor miracle -- it costs less than $11 delivered from Amazon.com. Here's the link

The scissors are made by Coghlan's, a company that makes all sorts of outdoor accessories. I chose the Coleman's version because it was least expensive I could find when I included shipping charges.
