[Air Wrench]

rope

We use ropes made of synthetic (Spectra) fibers from time to time in my line of work. A huge improvement over hemp, or cotton, or the yellow stuff you get at the hardware store.

[Air Wrench]

Gunpowder

Modern smokeless powers are an improvement to black powders.

buttons and buckles

My shirt has plastic buttons (not bone). My belt buckle is also made of plastic. They are inexpensive, light weight, and I don't have to take my belt off at airport security. Quite an improvement over stone, and bone.

Socks

Screwdrivers

Baking Soda and Baking Powder

If you go into a sporting goods store, you will see many improvements that have been made to socks. They are made of materials that better wick away moisture, and dry faster than many animal fibers. That being said, 100% wool is pretty effective too.

None of my screwdrivers have wooden handles. The metallurgy of the blades are quite different than those used in the late 15th century. Some screwdriver tips are magnetic. I have in my toolbox and ratcheting screwdriver with interchangeable bits, and interchangeable shafts. Quite a bit of improvement since invention.

Railroad tracks.

Chairs

There are Lazy Boy chairs with electric motors in them.

[Air Wrench]

Windows

You can get windows with coatings on the glass and gas between the panes.

Imbecils, they use computers now but they are still fun spoiling dungballs.

the arch.

Screw threads,
Wedges,
glass bottles.

I would disagree that screw threads have not improved since invention. They have beenstandardized for interchangeability, and improvements have been made to root shape help prevent cracks originating from the roots.

[Air Wrench]

Railroad tracks.

They used to be made of Iron, but they are now made of steel.

the arch.

Oh, good one!

you're pretty good at this! i was also thinking pins and needles.

Sewing needles have been improved:


I plan to get myself one of those for easily fixing snags in sweaters. :)

Sliced bread.
