You are looking at a premium woodcarving tool from Michihamono, a well-known Japanese brand. This chisel features a wooden handle that's long but light, making it easy to hold. Its simple design offers a nice grip, helping to make woodcarving a pleasant experience.
The tool's blade curves ever so slightly. It is indeed a U gouge, but incredibly shallow. This makes the tool excellent for smoothing or finishing with textures. This outstanding tool is also ideal when carving round circles such as eyes.
This professional tool is a great value. Quality made in Japan.
Please note: The background grid in the picture is in square millimetres. The handle is approximately 18cm long.
