Pinnah, wouldn't the screwed in pivot remove the 110 from the "traditional" classification to the "modern" classification?
The only knives I've ever had work loose on me were a couple Swenden Key Schrades.
That's a great question.
I think it really depends on who's definition of "traditional" you use. The guidelines on the Bladeforums Traditional sub-forum allows for screwed pivots. The primary 2 rules there are: a) no thumb studs/holes and b) no pocket clips.
IMO, Jared from JAG Custom Knives has really pioneered where I would love to see production Buck 110s to go, or least as an option out of the Buck Custom shop.

As I said above, the Buck 110 is probably strong enough for most people in most situations. Any lock back I've used hard (Bucks, Schrades, several others) have developed both vertical and horizontal blade play. I've generated horizontal blade play on many slip joints too, including a large Sodbuster with a very large pivot.
In contrast, there are traditional and modern designs that I've used that seem to withstand both vertical and horizontal blade play much better - so from a design standpoint, it's very possible. One in particular is dirt cheap too, so it's definitely not a matter of production costs or material cost. It's entirely a design and engineering issue.
Don't take this wrong. My Bucks are my most beloved knives and no knife I own is dearer to my heart. But, my traditional lockbacks (110s, 112s, 500) are among my least carried knives since there are others that are lighter, more durable (in terms of blade play) and have more versatile blade grinds (I've come to vastly prefer flat over hollow). These considerations all come into particularly sharp focus when choosing a knife for a backcountry trip. I want light weight, durability and versatility.
There is nothing that I like about Cold Steel knives but I think their Triad lock design is a positive step in the right direction. And I can definitely live with a knife as drop dead gorgeous as Jared's knife above.
I would love it if they brought back the Ecolite series. Thinner scales (for better pocket carry). Full flat grind (for more versatility). Triad style stop pin (to withstand vertical play better). JAG style pivot screws (to withstand horizontal play better).
