Ring Finger Saver
I work for a company that installs guardrails. While unloading the posts for a job, one post slipped and landed on my wedding band. I could not take the ring off on my own. I reached for my Wave tool and used the pliers to remove it. If I didn't have my Leatherman I would have had to run to a company work truck and looked for some pliers.
Our most popular model, with outside-accessible blades, bit driver, scissors, and wire cutters, all in a 100% stainless steel body.
