Introduction: Razor Blade Batarang
This project utilizes old razor blades and turns them into miniature Batarangs! At little to no cost, this is an easy afternoon project.
Step 1: Things You Will Need
You will need
-Old box cutter razor blade
-Dremel tool with cutting wheel and Sanding Drum
-Some form of a butane torch
-Batman logo template
Step 2: Light It Up
Use the torch to heat up the blade until it turns a metal blue-ish color. This is to make the blade easier to cut and shape. We will be re-hardening the blade later. You can cool it in water once it is sufficiently heated. When you take it out it should look like the picture above
Step 3: Cleaning and Dulling
use a high grit sand paper or sanding sponge to clean the surfaces of the blade. Once cleaned take a file to the edge to dull it down to make it safer to handle.
Step 4: Draw the Bat
Using the template trace the bat symbol onto the blade and for convenience of visibility fill in all the cut away space.
Step 5: Sparks Fly
Using the rotary tool/Dremel, cut the colored space using many straight cuts. You wont need as many cuts as in the picture, its just a diagram. Use a drum sander attachment for the rotary tool to smooth out the curves and file off the burrs.
Step 6: Re-heat and Quench
Heat up the Batarang again and quench it in the vegetable oil. Afterwards it should look kind of a dull grey. Just sand/buff the surfaces to get it to shine again.
Step 7: Paint
Put some tape on the very edge of the remaining blade edge to keep it a nice shiny silver. Paint the rest black preferably with rust-oleum or some primer/paint spray. Once that is dry peel off the tape and spray with one or two coats of a clear coat.
Step 8: You're Done!
That's all there is too it, use these as decoration or put a pin on it to make a lapel pin or tie tack, I am working on doing either of these modifications, if anyone thinks of a way to do it let me know, I am always open to suggestion. Enjoy working on these!
