There are several factors that go into my EDC choice:
- Ease of carrying it
- Ease of opening it
- Cutting/slicing performance
- Aesthetics
Ease of carrying it: I hate pocket clips. The only knives I've ever lost out of a pocket were clipped. On my modern knives, I take the clips off. If the knife is deep in my pocket, it's far less likely to disappear than if it's held right up near the opening of the pocket. I don't have much interest in giant tactical folders, so my only remaining modern knife (a Mini-Grip) rides in my pocket about the same as my traditionals.
Ease of opening it: There are certain circumstances where one-hand opening is useful (usually when the other hand is occupied). If I'm doing yardwork or house maintenance, I'm apt to grab the Mini-Grip instead of a traditional. (And if
@waynorth ever gets another run of the Stew's Blade one-arm barlows made and I'm able to snag one, I could pretty happily just always carry a slipjoint.) On the other hand, there are a lot of circumstances where I prefer to open a knife two-handed - it's a lot calmer and less threatening to anyone that happens to see it. (Knives are great tools and pretty lousy weapons, but one-hand opening a modern knife signals 'weapon' to a lot of people.)
Cutting/slicing performance: generally, well-made traditionals are better cutters than well-made modern knives. The blade geometry is almost always better. Thinner stock, full flat grinds, relatively narrow blades - they may not work as well for prying, but I don't do that with a knife anyway. And I can't think of anything I've done with a folding knife in the last few decades that would have worked better with the blade locked instead of a slip joint (or friction folder). I'm honestly not sure what value (beyond marketing) any lock brings to 99.999% of knife use. The one thing modern knives have going for them here is that good ones often use more modern steels. Stainless can be nice, but it's really the improved wear resistance you get with good steels that is good for EDC - it is really convenient to have an EDC knife that stays sharp for a long time.
Aesthetics: traditionals win this hands down for me. I like a knife that conveys elegance and workmanship. I dislike a knife that conveys anything 'tactical'. This is highly subjective - I understand that some people will feel exactly the opposite.
I think my ideal knife would be a traditional, but made with modern steels, titanium liners and bolsters, etc. I have a Lionsteel Warhorse, and I like it a lot, but I wish it was pinned instead of torx-screwed together, I wish the fitment was more like a traditional, etc. So, for now, straight-up traditionals are probably my favorite choices for EDC.
