In this video, I’m going to make a miniature throwing star. First, I designed it in 3D CAD on Autodesk Inventor. Once complete, I printed a few templates out to glue onto a piece of 1/4" thick mild steel. Normally any blade that I make, I’ll use high carbon steel and heat treat it to get the most strength and resilience out of the metal. For this, I was making the ninja star more for fun as a prop and not a functional throwing star. It it hit something, it would most likely dent and deform.
I started by drilling all of the holes out. This made it easier when cutting and shaping the star. Although the angle grinder made quick work of cutting into the steel, due to the width I could not get far enough into it. I needed a hacksaw to free the star. Once it was roughly cut to shape, the belt grinder was used for the final grinding.
A quick tip if you are ever grinding something small that can heat up quickly, grab a spray bottle and mist every so often. It’ll keep the metal cool enough to handle without removing a paper template. Next, the bevels were all ground in. I wanted this throwing star to have a weathered look to it so I gave it a deep patina. The solution that I used ate into the steel and pitted it, which was exactly what I hoped it to do. I plan to make a video on this solution to test it out further. After its “paint job,” the ninja star was complete.
