Dovetail hand plane with a sole sloped 15°.  Adjustable metal fence permits tail depth of 1/2". The scoring nicker can be adjusted as necessary to minimize tear out. The inclination and the pitch of the iron allow a skewed cut and easier sharpening because the iron is formed like a normal plane iron. The blade also guides the cutting forces towards the inside to prevent surface tearing along the dovetail tip. Very good condition with minor wear at the leading edge. See photos.
