If useful use is incorrect use, then yes.
By incorrect use I'm speaking of making a mistake. If you have less fear of a blade closing on you it a makes you more efficient since you've removed a variable that you had to account for previously. It also keeps your finger from being cut...
Agreed. I have caught and bent clips. I have also damaged the paint on a car with a clip. Kind of a trade off.
Same here, but it is an acceptable trade off.
I can actually open most of my traditionals with one hand, but it can be fiddly. If I'm on a ladder, I've usually got a work knife like a 110 that's easy to open one-handed. Or a real knife. The kind that isn't pre-broken in the middle.
Agree 100%. I'll note that properly heat treated 1095 performs well. It just rusts easily. There's no excuse for using a stainless that doesn't perform at least as well as 1095.
I suppose. But a knife is a last ditch defensive weapon for when you don't have a club handy. And a club is a poor choice compared to a pistol. And a pistol is a back up weapon for when you don't have a long gun. If it gets to the point where I actually need a knife for self defense, I'm totally screwed anyway. If I was younger, stronger, and had spent the necessary years in training to effectively use a knife as a weapon, it might be a different story.
I addressed this in a previous post. But what I didn't say was that my reason for liking a larger blade is not entirely for self defense, but for the fact that you have more blade to work with. More blade means more blade area to use.
In many ways moderns are more practical. I own a few. But they seldom get carried. Personal preference, no right or wrong.
Personal preference, agreed.
