I guess I'll have to join that camp.
If I have to fight with my knife to get my knife open, then I won't be carrying that knife. It must be a collector thing. I don't know of many working men that would put up with it. The Old Timers were a perfect example of a knife that had a cult following among those who got thier hands dirty. I haven't seen too many nail breaking Old Timers. Or the old TL-29's. Even as 12 year old kids, we had no problem opening the ones we got at the surplus store for 75 cents.
Out on a job, your hands could be a bit slippery with water, cold, mud, dust, oil, anything. A knife that you can only open in clean dry conditions, or with a second tool, is not good. Something is wrong. Nothing should ever get in the way of function, even in a collectors piece. I've often though that Victorinox should be the standard of pocket knife production. Somehow they make ALL thier knives open smoothly, with the same amount of pull. Why can't GEC or some of these 'other' makes? Or take Buck for example. Very few nail breakers there. My old Buck stockman had what some here may have called soft springs. But in 25 years of use, they didn't get any softer, but they didn't interfear with the cutting either. It still opens pretty easy compared to some of the new stuff.
I think some manufactors go a bit overboard on the spring thing.
