1. Draw the desired plastic knife shape on a piece of paper. Cut out the paper template and lay it on the acrylic plate. Draw around the template using an oil pencil.
2. Cut out the knife shape from the acrylic plate using a band saw. Cut slowly and precisely.
3. Secure the blade end of the plastic knife clip art in a bench vise between two rubber squares to prevent scratching the surface. Round the edges of the handle using a flat file. Add a curve between the handle and the blade using the round file.
4. Remove the blade from the bench utility knife. Secure the handle of the knife between two pieces of rubber in the bench vise. Make sure the top edge of the knife is up if making a one-sided blade. Shape the top of the blade using the flat diamond file.
5. Flip the knife over in the bench vise so the blade of the knife is facing up. Shape and bevel the blade on each side using the flat diamond file. Do both sides of the blade at the same bevel. The blade will be sharp at the end of this process, but requires two more steps.
6. Use plastic polishing grit on a soft rag and polish the entire surface to remove any scratches. Use the plastic polishing grit on the blade to create a sharper blade. Clean the polishing grit off with water after the desired sharpness has been reached.
7. Use diamond rouge as the final polish. Diamond rouge is a compound used by jewelers to polish jewelry. Polish the entire plastic knife using diamond rouge. Concentrate on the blade to finish off the blade sharpening.
