Chute Guide Scabbard / Household

Chute Guide Scabbard

During inserting cutters in the scabbard, it is not convenient to put the cutters into the scabbard due to a small scabbard mouth and the fingers are easily scratched.
The scabbard mouth is now designed with a concave cant which is convenient for putting the scabbard into the scabbard.
