The 110 is kind of a knife from long ago that is both caked in nostalgia and performance. In the long, long ago, there were no forums to pour over. There were no YouTube experts delving into the most minute of details of what is good/bad about a knife.
The 110 was what it was, and still is, a chunk of brass and wood with a locking clip point blade of stainless steel. It was a workhorse that most could afford but wasn't a beater. It was designed to be the folding knife a hunter could rely on, it became the biker's knife of choice, and it ended up on the workbelt of a generation of contractors.
They are heavy. Centering is a bit hit and miss, but within spec. The steel of those from a clam package in a box store is mostly just serviceable compared to what we can get today. The only way to carry them easily is in a pouch (I still remember the work/sweat worn outline of a 110 on my dad's front jeans pocket from him carrying it loose).
Short of getting a custom, some slop is generally to be expected as you can't really tune them. In many ways, that can be frustrating. In others, it's kinda cool to see something survive long enough to be copied by dozens of makers yet still be able to sell the "real" version of itself over half a century later. I'm not going to defend the 110 as the ideal knife for anyone these days who is really honest about what they need. I feel they are antiquated for all intents and purposes compared to what you can get...but don't tell my dad that

. He still dresses to work every day. He still slides on his work jeans. Instead of a worn spot on his pocket he has one of a dozen sheaths I've made him over the years, but he does not leave the house without his 110 on his hip. It's a habit that he's acquired over the last 50 years.
110s kinda are what they are. Just like my old man.
