General's Pocket Scribers provide powerful scribing and etching solutions in a travel-convenient design. The locking screw chuck allows the point to be reversed into the body, condensing the tool length to about 4” and protecting the point when not in use. The hexagonal head prevents the tool from rolling off an uneven work surface. This particular item is our larger, 3/8" diameter Pocket Scriber with a 2” replaceable steel blade.
