I used to carry the same knife for years at a time, until I either broke it or lost it. It’s easy when your primary focus with a knife is as a tool.
Here’s a little secret most BF members don’t like to admit to ourselves - the average person carrying a knife, only has one, and it’s usually a pretty cheap one. And guess what, they usually work just as well as all the fancy, high priced ones we like. In fact, through my teens and early 20’s, I routinely carried around knifes I bought for $10 at flea markets or in the outdoors section of Kmart, etc. If it got dull, I ran it through the sharpener on the electric can opener in my mother’s kitchen. If I broke the tip off while prying something, I reground it on the bench grinder. If I lost it, I replaced it for another $10.
Even after I discovered ‘better’ knives, I still only carried one. For the longest time (probably close to 10 years) it was an old Kershaw Blackout. Then for a few years, an assisted Gerber (don’t remember the model), followed by a Leek, and most recently a Manix 2.
I could easily do a 30 day challenge again today. My knives are still primarily tools for me. For the last 2 weeks I’ve carried a Spyderco Dragonfly almost exclusively, considering I’m not working, and primarily living in basketball or running shorts, and it’s done most of what I’ve needed a knife for. Maybe I’ll just keep carrying it exclusively for a while.
The question is, what consists of ‘just one’ for 30 days? EDC is one thing, but what about things like camping, house projects, or food prep? Does the 6” fixed blade in my camp bag count against me? What about the utility blade in my toolbox? Or my 8” chef’s knife that I’ll be breaking down chicken with tonight? Anyone ever use one edc exclusively, for everything, for 30 days? Now THAT would be a challenge!
