I've had a few old hand-forged iron flints over the years, but none as lovely and special as this, with the treatment of the iron very akin to that seen on 17th-18th century scrollwork fireplace tools, and I would guess this is that early. The flat of the bottom, which is the striker, is worn very smooth from use, as I've tried to document. Found it at a shop in the Hudson River Valley. Beautiful object.
3 1/16" x 1 3/16" x 1/4". Aging to the surface of the iron, as there should be. Striker worn very smooth.
