Made by Hokiyama Hamono, these knives are marketed under different names. They are a nice affordable option and a great bang for the buck. 

Use & Care

• Do not attempt to cut, hit or chop frozen products or bones. The blade can chip or break with improper use.
• Hand wash with warm water and towel dry. Never put the knife in a dishwasher, nor soak it. Ever!
• Use a sharpening stone to maintain the sharpness of the blade. 
• Do not use on hard melons or items that may torque the blade.
