I am a woodworker who makes decorative boxes and for a larger tool chest that will be in a public area, I'm looking for something a bit better than the 3 or 4 standard skeleton-key style locks that you traditionally find in various woodworking stores. Just something slightly more difficult to open.
Ideally something without a large visible external escutcheon would be nice.
Mostly I've used stuff from horton brasses and whitechapel.
Any suggestions?
