Introduction: Batarang Out of Lawnmower Blade

If you're like me, you have always loved throwing things around and getting them to stick. And just like every 15 year old Boy Scout, I love sharp things. Being a semi avid fan of Batman I love the idea of throwing around a batarang like he does in the movies. So I decided to make one and show how I did it. If you're like me and you have some time in between your home schooling classes you might as well join me and make one of your own batarangs. They are fun to throw, easy to stick and when they do stick, they stick good. So sit down, take off your shoes and stay for a while, while I show you how I made my very own batarang.


Tools I Used:

  1. Vise
  2. 4 1/2 inch angle grinder
  3. assortment of files
  4. large clamp
  5. sandpaper (i used up to 220 grit)
  6. belt sander with assorted belts

Materials I Used:

  1. lawnmower blade
  2. oil/wax to protect from rust
  3. printed outline of batarang
  4. can of spray paint

Step 1: Gather Your Supplies

If you're like me, you have a dirty workshop! You might need to clean off your work table. Go ahead and do that. After you're done, get your tools and lay them out where they are accessible.

Step 2: Make the Design

First, I got the lawnmower blade. Then, I placed my printed design on top of the blade. Holding the template down with my fingers, I spray painted around it. You can weigh it down with something other than your fingers if you choose, you're just trying to keep the spray paint from getting underneath the template, so your design comes out crisp and clear.

Step 3: Cut the Blade Into an Easy to Work With Size

After painting the design onto the blade I cut off the two unneeded ends to make the piece into a more manageable size (DO NOT THROW THEM AWAY THEY ARE STILL USEFUL!).

Step 4: Rough in the Shape

I used my angle grinder to cut off extra materials to create the general shape that I wanted. This step isn't super crucial to the project, I am just trying to hog out material.

Step 5: Refine the Shape

Next I used a combination of my angle grinder and my belt sander to refine the shape of my batarang and get it as close to the finished product as I could.

Step 6: SANDING TIME!!!!!!!!

I used my belt sander again with the 120 grit sandpaper to remove the rust and grime off of the batarang. Then I hand sanded the faces with 120, 150, and 220 grit sandpaper until they were smooth and shiny.

Step 7: Im Done!

After I sanded the faces for a while I decided to do a decorative bevel on the edges of the blade. It kind of served a purpose though, because it sharpened the tips of the batarang too. Now all I have to do is throw it and bask in the glory of what I have just created. If you followed along with me you too can do some basking, but you should also add a little bit of wax or oil to the blade to stop it from rusting.
