+1 on what Canoedogs said.I have had to borrow some one elses multitool to do just this very thing.If one is alone,they are out of luck.It's like them cheap hobo knives with spoon,fork and knife that do not come apart.How can you cut your steak and hold it with the fork simultainiously.I think a small pair of regular slipjoint pliers and a SAK works good.Vice Grips in a six inch size is an other option.An easy mod to them is chainging the adjustment screw with an eye bolt.It lends itself to many more uses(pothanger,game processing,etc.)and can be carried on a carabiner.Dave Canterbury has some interesting ideas on multitools and vice grips on his youtube channel.....
