American Machine-Made

Akro Agate

Akro Agate is one of the best known American machine-made producers, associated with corkscrews, patches and a wide colour range.

What to look for

  • Corkscrew construction — a spiral running pole to pole — is a signature look.
  • Colour combinations matter more than size in this family.
  • Machine seams and as-made pits are manufacturing marks, not damage.
