It is equipped with an old wooden plane blade which thickness is considerably higher (ca. 4 mm) than the original one and it has a 10°back bevel* and then a 55°cutting angle, very good for "difficult" grain.
* Using the plane I found it very hard to push so I decided of decreasing back bevel value to 10° instead of 15°. This last is good for a narrower plane as a #4.
