Query: Not for use with Cold Steel

the seller delivered it promptly and they deserve a high rating. the product itself however is poor. The sheath arrived slightly bent and seems to be made of very poor plastic. Also other reviews not how well the sheath works with the cold steel bokken and how snugly it fits, the reason for that is the sheath and the bokken have different curvatures so the bokken will fit tightly, but that it because the bokken resisting getting deformed by the sheath. my cold steel bokken has been scratched and damaged by this product particularly on the back spine. also the hard edge on the inside of the mouth scratched the front of my bokken as well. overall I would not recommend this product especially for use with the cold steel bokken.
