I spent yesterday in Arnon Kartmazov's Bridge Town Forge shop in Portland Oregon. This wasn't my first visit there but it is always super interesting watching him work. He forged 15-inch blade gyuto from raw bar stock using two power hammers and two furnaces at the same time. An anvil was set between the furnaces for the fine hand work. Looking around at the work in progress, I have the impression over size qyutos must be very popular with foodies in Portland.
