G'day Guys,

Below are two different examples of Gassan Sadakatsu's masame hada. The top blade is dated 1940 and has very tight masame hada, with little contrast between layers. The bottom blade is dated 1938 and has high contrast between layers. I believe he achieved this contrast by combining different steels in alternating layers. This is the type of contrast you usually see in his ayasugi examples. I assume he used a single type of steel in the top blade.

Cheers,

Bryce

The hada on the 1938 example (top) is very similar to this 1943 example (bottom) with ayasugi. I guess the smithing process is identical up to the point where the layers are mechanically manipulated into the wave pattern.

Cheers,

Bryce
