As a fan of both Leatherman multi-tools and entrepreneurialism, I enjoyed the story of How Tim Leatherman outdid the Swiss Army knife:
My wife and I decided to travel abroad in 1975. We were young-it was one of those budget trips, and we bought an old Fiat in Amsterdam for $300. I was carrying a Boy Scout-type knife and used it for everything, from slicing bread to making adjustments to the car. But I kept wishing I had a pair of pliers! During the trip — it lasted almost nine months — I had a piece of paper in my pocket where I listed ideas for new products, things I might work on back in the U.S. It was in a hotel room in Tehran that I started sketching a pocketknife that contained pliers.
Once we got back to Portland, I asked my wife if I could build it — just one for me. I told her it would only take a month, and she got a job to support us. I set up shop in the garage and picked up a file and a hacksaw. (I have a degree in mechanical engineering but knew nothing about machining.) My brother-in-law was a machinist, and what he didn’t teach me about metalworking, I had to figure out myself. My month turned into three years. I learned that I’m not a very good inventor. I don’t have much foresight. You know Marconi, who built some of the first radios? I’ve heard that before he picked up a pencil, he had the entire model envisioned in his mind. I’m not that way. It took a few months just to visualize each part of the knife.
The first concept was a knife with a pair of regular pliers, and then a separate needle nose would swing over and be driven by the pliers. Then I got really ambitious and decided to add a feature that would lock the pliers, so that once I’d grab onto something, they would stay clamped. I wanted to put in a hacksaw, but they wear out pretty fast. I even tried to put in a can opener, a flat screwdriver, a leather punch, a pair of scissors, and a Phillips screwdriver. Eventually I ended up with two prototypes.
At that point I filed for a patent. I was hoping for an easy way out, that someone would pay me a million dollars for the patent rights. I thought my most likely prospects would be knife companies, so I brought my prototype to Gerber, a Portland, Ore., knife business. They looked it over and said, “This isn’t a knife, it’s a tool. We’re not in the tool business.” I still thought it was a knife, so I went to the major knife companies, but they all said no. I eventually got the message, and decided that if it’s not a knife, it’s a tool. I visited several tool companies, and they all said, “This isn’t a tool, it’s a gadget. Gadgets don’t sell.”
It took eight years before the tool took off. Read the whole story.
