Cut a plank of wood 3 inches in width and 10 inches in length. The plank should be about 2 inches thick. Mark the midpoint of the width of the plank, and draw a line running along this midpoint, parallel to the two long sides. This will be the ridge in the middle of the sword.
Mark a midpoint in the thickness of the plank also, and use a hacksaw to cut a rough diagonal from the central line to the midpoint of the thickness. Do this on both sides of the central line; then turn the plank over and repeat. The plank should now have a diamond cross section.
Make a mark on both long edges 3 inches from the end of the plank. Saw a diagonal cut from one of these marks to where the central line touches the end of the plank. Repeat this from the other mark to bring the blade of the gladius to a point. Plane all four horizontal surfaces until they are uniformly smooth.
Cut a piece of dowel to 7 inches in length. Drill a hole in the dead center of the nontapered end of the plank, equal to the diameter of the dowel. This hole should be 1 inch thick. Drill an identical hole into the dead center of the base of the cupboard handle.
Apply wood glue to each hole and insert one end of the dowel into each. Leave the gladius to dry, and then use a file to remove any excess dried glue or untidy edges of the wood.
Spray the gladius with a coat of white primer; then allow it to dry before spraying the whole piece silver. Hand paint the handle of the gladius with a deep mahogany brown, taking care not to splash any on the blade part of the sword.
Dip your brush into some black matte paint and wipe thoroughly with the tissue paper. Paint the blade of the sword with the remaining flecks of paint on the brush, returning to the pot to dip the brush and wipe with the tissue after every four or five strokes. This gives the silver a rugged, aged effect, making the sword look more realistic. This is a technique known as dry brushing.
