When did double-shot keytops disappear?

[Chuck Guzis]

I was looking at a not-very-old HP keyboard today and noticed that the
lettering on the keys is wearing away after only a few years of use.  

Another corner quietly cut, I suppose.

Used to be that keytops were double-shot molded, with the lettering all but
indestructible.  Is this a practice that's gone forever, or is there still
a vendor who makes keyboards the old way?

Cheers,
Chuck
