I spent years exclusively carrying modern folders. Frame locks, flippers, and funky grinds were never my thing but I like my modern knives for sure. For me, modern folders have always been very utilitarian oriented with ergos and performance far outweighing looks.
A while back I decided I wanted to try something different. I was largely bored with what I was seeing in the modern knife world and had done so much experimenting that I'd really found the designs and steels that worked for me. And when something new did catch my eye it was all too often a sprint or at a price point that I was just not willing to pay.
My wife had purchased a Buck Canoe for me at some point and so I just tossed that thing in my pocket to see how it went. And much to my surprise, after a few days of initial adjustment, I realized the two-hand opening and slip joint weren't really a hinderance at all. The blade size was no big deal as I frequently carried a Dragonfly.
And so more and more knives in this venue started to find their way to my house. Case knives aren't the highest quality in this category but they aren't bad for the price, have a lot of variety, and are so affordable that I found myself really having fun experimenting again. I was trying out different patterns and really enjoying the process. And at no time did I feel want for a modern knife.
Now, that is in no way implying that I abandoned modern knives. That, to me, is silly. If I knew I was going to be needing a knife for more work-oriented tasks then I'd most likely toss one of my M2LW's into my pocket. But day in and day out, my EDC was most likely an "old timey" knife. I did and still do very much like the Case Mini Copperlock. That's a back lock as are other "old timey" knives but still no where near modern.
And that all taught me that my immediate dismissal of slip joints at the least was unfounded and caused me to miss out on some real nice knives out there. Then I started finding slip joints that I really like and that are beautiful. Laguioles, Chambriard Compact, modern traditionals like my lionSTEEL Gitano and Buck 501 in S30V, and so on. These knives really make me happy when I use them.
With that "must have a lock and one hand opening" mindset purged, I'm finding some great knives.
Again, in no way do I think it needs to be an either/or and people should use the right tools for the right jobs but I just think, from personal experience, that dismissing so many awesome knives for reasons that in reality are often not relevant, is quite unfortunate.
