      • Use a brass wire brush to scrub the rusted areas.

      • Focus especially on the blade and any areas that will contact the sharpening stone.

      • Use a clean rag to remove any leftover WD-40 or rust residue.

      • Soak the wet sharpening stone with water for a couple of minutes and place it on a flat surface.

      • Hold the chisel at a 20-degree angle and push it forward against the stone to grind the edge. After each stroke, lift the chisel and return it to the starting position.

      • Repeat this motion on both sides of the stone until the chisel reaches your desired sharpness.

      • Water acts as a lubricant, helping to carry away metal particles and prevent clogging during sharpening.

      • With a rag, carefully wipe of any debris and metal shaving possible left on the chisel.

      • Use caution—this blade is now significantly sharper.
