I get it. It just seems to me a 4" blade would need a stronger backup. My taste here and as America has a strong fixed blade culture it's probably that american folders are just designed for random utility tasks. I'm currently reprofiling a Queen Folding Hunter which is a very beautiful knife, and I don't mind it came dull, but I wonder how such a heavy knife with such a thick and powerful blade and oversized handle can fit in any EDC, given the weak spring. Just wondering. I use also friction folders which are to be used with care and I generally understand a folder (whatever strong spring or lockup device) is to be used just as that : a folder... Then I grab a (relatively) cheap industrial lockback with no play at all, razor sharp blade and minimal weight... And I just wonder. No charm, no soul, indeed... but what a solid feeling. Sigh... Currently on the edge of ordering a Northfield collector. Will do, most certainly, because I'm a fool for beauty and romance.
