Steel has a flowing wood grain layer pattern on the ridge side. And you can find beautiful steel particles by careful studying.
On the flat side, the steel has a compact steel layer.
Hamon pattern is straight. The temper line on the flat side is tight and neat, while that on the ridge side is not so. Probably the steel is different on each side.
