Cut the 2×4 board into two 4-inch sections. Then, cut each of these 4-inch pieces vertically down the center, resulting in four 1×4-inch pieces. You’ll only need three pieces, so set aside or discard the fourth.
Using a miter saw or hand saw, cut facets into each wood piece to create an angular, crystal-like shape. Work carefully, cutting at various angles to achieve the desired look.
Use a belt sander to smooth rough edges and add additional facets. To do so, press the wood block’s corners into the sander, holding it in place until a flat plane forms. After sanding, each wood piece should be approximately 3.5 inches long. Repeat Steps 2 and 3 for the other two wood blocks to create a total of three “wood crystals.”
Drill a hole at one end of each wood piece using a 7/32-inch drill bit. The hole should be snug to fit the metal cheese tools securely.
Apply two coats of spray paint to each wood piece, allowing the paint to dry fully between coats.
Once painted, seal the pieces with a high-gloss polyurethane spray and let them dry completely.
Slide the bolster onto the unfinished end of the metal cheese knife.
Insert the unfinished end of the knife into the drilled hole of the wood crystal. If the fit is too loose, apply a small amount of industrial-strength adhesive inside the hole before reinserting the knife. Allow the adhesive to dry for a few hours if used.
