Made in Sheffield by Joseph Marples, this Rosewood 1:8 dovetail marker has a brass face and blued steel blade secured with three brass rivets.
Used for laying out dovetail joinery, the 1:8 ratio produces a more refined and attractive joint than the 1:6. Usually used on harder timbers, the 1:8 is commonly used for feature dovetails slender London pattern dovetails on drawer fronts, or perhaps the more complex hounds tooth pattern.
