Byzer USA is now Cloudhammer Steelworks.
This site is in BETA. You can place orders, but there might be customizations we need to clarify.
Technically pattern steel, "Damascus" blends together different types of steels with different properties to create whirling patterns in the blade.
Cloudhammer swords typically combine a spring steel with a harder tool steel, and can be done with several patterns.
Most of the blades have to be custom ordered, though there are sometimes samples available for sale.
