This shoulder plane is made from premium grade macarssar ebony. It is equiped with special tool steel blade, which is secured in place with ebony wedge.
This type of plane can be used as a trimming tool to fit shoulders, rabbets and dadoes.
The blade requires honing before first use. A small hammer(3-4 OZ) can be used to adjust depth of cut. Tapping the heel of the plane will loosen the wedge and blade. Start with lightest cut as you can at the very begining, after you get more familiar with the tool, you can increase the depth of cut by tapping the end of blade.
