While it's true that blacksmiths can collect anvils, anvils are known for collecting owners! Anvils will often outlive the person who bought them and are still very much useful so the market for old anvils thrives and you can find these on DoneDeal or Adverts.ie. But a brand new anvil is tricky.
A brand new anvil will function the exact same as an old anvil. But buying directly from the manufacturer means it's in pristine condition - no chips, the face is as hard as it should be, and so on.
This page is about finding a new anvil in Ireland.
