If I recall, a little further up the page it had some translations of terms and I saw mention of the laminated blade:
"Sirogami: Japanese carbon steel, Tasou-kou: Laminate steel has ripples like japanese sword"
Murray Carter also produces some beautiful laminated/san mai blades.
Murray (for those who don't know)is a Canadian living in Japan who forges blades in the Japanese tradition.
I was fortunate enough to pick up a nice piece from him at this year's Blade Show where he earned his master smith rating.
Japanese blades (and those derived from Japanese tradition) are amongst my favorites. (If not my very favorite of all blades.)
