A bucking iron is set against the nail head so that it doesn't back out while setting the copper rove over the nail or during the peening process.
The bucking iron included here has one end slightly rounded for flush nail heads, and a narrow tapered end for countersunk nails.
I have modeled these based off of a set made by my instructor while I attended the Northwest School of Wooden Boatbuilding.
These tools are both made from 1 1/2" shock-resistant S7 tool steel stock, on a manual metal lathe. They have been hardened and tempered to resist dents, dings, and improve the life of the tool.
