Things You'll Need
Instructions
Purchase a sheath for your knife. This is particularily useful if you intend to use the knife as well as display it, as you can simply hang the sheath on a wall from a nail or from adhesive, or simply carry the knife with you wherever you go.
Place the knife in a display box. Display box exist that are made specifically for knives. Simply open the box, place the knives in (You may need to fasten them with a nail or cut foam for them) and close them. Like the sheaths, you may hang them on a wall or place them on a counter.
Purchase drawer knobs from a local hardware store, along with screws for drilling into a wall. (Ask an employee of the store for assistance if you don't know what screw to use.) Drill the screws into the wall, place the knobs on the screws, then hang the knives in between the knobs. Note that you may want to drill into a stud for heavy knives.
