Razor Plane

Your Master Airscrew Razor Plane has been engineered to use a special .017" x 1-3/4" blades and the depth of cut can be adjusted with the two blade strop screws.   It is important that the blade be as sharp as possible when cutting balsa, especially if cross grain work is done.  Replacement blades are available.  

When cutting with the plane, the best cuts are made with the nose of the plane to one side of the direction of the stroke.  Some experimentation may be necessary to learn this technique used by experienced craftsmen.  For storage, lightly oil blade.
