It seems that for some jobs, you need three hands to get it done. Your pliers can lend you that extra hand. Use the pliers to grip the wire or small piece you need to have held. Then wrap a rubber band around the handles to maintain the grip while you complete the work.
If you are working outside of your shop or garage, running for individual tools can slow down a project. Instead, stack all the tools or toolboxes you will need into a wheelbarrow. Then you can wheel off to the job fully equipped or invest in a rolling project center.
