A favorite of decoy carvers, ruby carvers were originally designed for working acrylics where they leave a satin finish.
They are effective in a wide range of woods since the ruby particles retain their sharpness and are non-plugging in use. Used for undercutting, contouring and feather detailing, they have a wide application in all types of woodcarving.
Shanks are 3/32" dia. by about 1 3/8". Available individually or as a set of 10.
