New Old Stock. Think about the 50-years old Minamotos
Minamoto no Masakane Gyuto 270mm wide
With the K-Sabatier the story is a bit different. They had huge stocks of Nogent carbon blades they put a handle on — no ebony but birch — and an aluminium virole. Stocks from other makers who went in bankruptcy in the '29-crisis, own stocks from the 50s.
And some full-tang carbons meant for export, as the so-called Canadians, with only a narrow fingerguard. There's not much left with K-Sabatier itself, I'm afraid.
Bernal in California still has some.

The original ebony handles were bored down the center with a large diameter hole, leaving just a thin web of wood on the sides. They look solid, but they're not. Very light. German handles from the same time are often in massive rosewood with a neutral balance. The modern massive beech ones are very light as well and don't disturb the traditional forward balance.
