Tools generally don't, I know they have added some antivibration stuff to hammers but an old hammer still works.

As far as socket sets and crow bars go I can't think of a new feature that happened in my life time.

For screw drivers the biggest change is companies keep inventing new heads for security by obscurity reasons, not better performance.

For screw drivers that may be the case now, or it may not be. Screws became popularized in the 1700s, but it wasn't until the early 1900s we see evidence of people trying different heads (square head), and it wasn't until the Phillips head in the 1930s that we adopted a standard. Even then it was a while before it entered consumer goods; I encountered a 1940 Fibber Mcgee and Molly episode (which is what led me to looking up the history of the screw) where Fibber went to buy a screwdriver, and literally asked for "a screwdriver with a black handle", no other qualifier, and the shop keep didn't ask for clarification.

Screw drivers, who need them when you have a perfectly good hammer, amirit?

Reminds me of a joke I made in passing by the pool this summer. All the ladies were drinking their hard seltzer cans, which is very trendy last couple years in US anyways. All of them using the Yeti/similar insulated can holders (coozies). My joke was something about how the entire beverage industry aligned on a new narrow and tall can size for seltzers just so they all had to buy new drink accessories
