Double Ended Planishing Anvil Stake
A vintage tinmans or smiths curved double ended anvil stake.
The larger face is 11/4 inches (31mm) wide, the smaller is a little under 1" (25m) square.
Both faces are slightly convex.
The smaller of the faces may not originally have been intended for smithing use but has clearly served this purpose at some stage.
The square shank fits nicely in the hand.
Approximately 6" (150mm) overall.
