Left Handed Knives
Japanese Traditional Single bevel Knives,such as Deba,Yanagiba,Usuba Knives, etc., are basically designed for Right Handed. In spite of Left handed users(especially Professionals),they were forced to use normal Right Handed Knives in the past.
For Left handed, the construction of base tang and manufacturing process are completely different. Therefore, Single bevel Left handed costs 30-50% higher than normal ones.
