Yes! I have a razor with Navaja on it. Some curiosity found that it (Navaja) originally refers to a wicked knife back in Spain which was carried covertly by men and women as the government outlawed weapons. Interesting subject, it seems that many were made, carried, and exported. Many varieties, some were extremely intricate and fancy. Highly collectible! The first lock-backs were introduced. The term has been used to advertise a sharp folder ever since.
