On this Japanese tool, the small, anvil-shaped head is actually a second nail set, meant for striking 8d nails in tight spaces. This 6½-inch-long tool has a 5mm (roughly 6/32-inch) tip for sinking big 12d to 20d finish nails or driving chunky flooring nails into antique floorboards. To eliminate the chance of missing the mark, these tools have a hollow shaft that slides over the nail and rests on the wood.

To use this spring-loaded, “hammerless” nail set, you hold the bottom half in a tight pincer grip and pull the top half away from the nailhead.
