Hi all. This is a sword I have, and it is pleasing in every way, in 1972 it was submitted to the NBTHK for Kanteisho and was issued a Tobubetsu Kicho. The sword is attributed to Kanetane in the province of Echizen circa 1600. Blade length is 69.7cms. Can you tell me what style or name is given to this hamon on the blade. It always appears to me to be a panoramic view of a cloudy sky. In another post I will show the tsuba, that came with the sword. Thanks Denis.
