This is a scrap metal neck knife, my daughter named the "Metal Mouse" .
Step 1: Find some Steel!
Find some steel! Old tractor parts, car parts, Truck parts, Leaf springs, seat belt brackets and clasps from Junked Cars & Trucks, scrap yards, salvage depots,etc...!
Step 2: Clean it up
I use a grinding wheel, wire wheel, and Buffing wheel. Mounted on an old refrigerator motor shaft. PLEASE be careful!
I can't stress how dangerous flying metal and even the dust can be. You must wear appropriate face shield, goggles, gloves, etc...
Also when using the wire wheel to remove rust from metal, the thin wire strands can fly off the wheel at great speeds!. I have had them stuck in my shirt, skin, and arms. Please wear long sleeve shirts, gloves, face shields, an apron, etc.. I have been doing this a long time and wish to save you a trip to the ER. Be safe! Let an adult do this for you, if you have had no experience with these tools!
Step 3: Trace your pattern onto steel.
Use a permanent marker!
Step 4: Cut it out!
The Grinding Wheel (stone) does most of the work. Some of it can be done with a Jig Saw with a metal cutting (carbide) blade. Or, the slowest way, use a hand held hacksaw! Again, use appropriate safety protection, face shield, leather gloves, shop apron, long sleeve shirt, long pants (those sparks can burn) . Button all shirt sleeve cuffs, remove all jewelry too! Be careful. Metal can fly very fast!
Step 5: Drill holes for Lanyard.
Some scraps have holes already in them. Try to work them into your handle to save drilling . Clamp your pieces down. They can spin without warning !
Step 6: Grind, polish and sharpen it up!
Use appropriate safety measures here too! I added a cammo & blaze orange lanyard to it! I'm addicted to paracord!
