I was wondering if anyone could help me identify these knives? My parents bought them for me when they were in Japan several years ago. From what I remember they were hand made by a 10~12 generation sword maker.
Also - what kind of the steel is the silver one made from (I understand the darker one is carbon) - I assume some sort of carbon. Is this white paper steel? How should I go about polishing? Along the edge were some dark marks - I read baking soda and a potato / cork would be a good way to polish. I assume this is ok?
The darker blade is about 5 inches and the silver blade is about 6 3/4 inches. If you'd like to see a larger photo to read some things better I can upload one elsewhere.
