Edge guard covers prevent damage on knives during transport. We strongly recommend purchasing knife covers if you are frequently traveling with your knives. 
Because they are hand made we sometimes have fitting issues with our wooden Saya sheaths. On the other hand, these edge guards are much more forgiving and will not have a problem as long as your knife is shorter than its maximum blade length.

Specifications:

Knife Type: Gyuto 180mm, Nakiri, Santoku, Bunka

The Saya does NOT fit these knives;

• The sheath is designed for knives we carry. This sheath might not fit knives other than ones listed above. We make sure knife and sheath matches when they are purchased together before shipping. If you purchased only sheath, we can’t guarantee that all sheath goes with other knives, and we will not accept an exchange or return.

It usually takes 2 –3 month for us to restock should this item is not available.
