SHINZAN Hammers by Makoto Aida

In Japan, Makoto Aida is a well-known hammersmith. Under his brand SHINZAN, which freely translated means "Deep Mountain", he produces carefully crafted hammers with heads that feature a so-called "tsuchime" pattern. With delicate blows of a hammer he creates a surface texture that is then polished. This results in a compelling finish with a usually brownish and sometimes bluish tinge. Selective hardening of the striking surfaces means that part of the recoil energy is absorbed by the somewhat softer core of the steel. You feel you’re working more effectively, also because less of the recoil energy makes its way back to the wrist joint.

These hammer heads have one flat and one slightly convex striking face. Use one or the other face, depending on the job at hand. The flat face, for instance, is used for tapping chisels or for driving in nails close to the inside edge of a workpiece. The cheeks of the hammer head glide over the surface of the workpiece, so you can be sure that the striking face is exactly at right angles to it. This provides you with the best chance of knocking in small nails dead straight even in an inconvenient location. For setting nails you use the convex face of the hammer to minimise the risk of damaging the surrounding wooden surface.

The hammer is supplied with a handle made of white oak. Note that the hammer handles are fitted in the more humid climatic conditions of Japan. Our comparatively dryer climate can cause the wooden handle to shrink slightly and become loose. If this is the case, you need to refit the handle and possibly readjust the hammer head. The best way to do this is to knock the end of the handle onto a firm surface. Keep checking that the hammer head is at right angles to the handle and correct as necessary. Finally, drive the wedge at the top a bit further in with a hammer, if necessary. These hammers are hand-forged, so you may notice slight deviations in weight and dimensions.

Note: wedge is included but not always mounted.
