The wooden body is prepared for use, but minor adjustments may be necessary to achieve optimal precision.

Usage and maintenance tips

• Prefer planing softwoods, for which this steel was selected.
• Check the adjustment of the blade and the counter-iron before use.
• Make the necessary adjustments to the body and the cutting edge to obtain fine and even shavings.
• After use, always retract the cutting edge into the body of the plane.
• Store the tool in a dry place to protect the blade from corrosion.
• Maintain the cutting edge with sharpening stones suitable for traditional steels.
