This is where new world can actually help old world.

Screws are just fasteners. It's a helical inclined plane to hold stuff to other stuff.

These gun screws with narrow hand cut slots look good... until the first disassembly. Then they start to look like hell.

'Cobbled', 'mistimed', etc.

There is no need for this at all. If ever there was an application screaming for a modern fastener drive system, this is it.

OMG! Blasphemy!

But really... any modern drive system, starting with a 'Security Torx' could be engraved as part of the pattern. That would look worse than a mistimed cobbled narrow slot how?

This would not necessarily require a screw machine part, just a screw made from stock with the drive system already cut in.
