This is my version of the legendary Radiance from the Valve game DOTA2. Inspired by the "burning effect" this sword glows when placed on its stand. It's made from acrylic and maple hardwood with orange and yellow LEDs built into the crossguard.

Step 1: Blade design

My first step was to acquire the thickest acrylic sheet (.22") for the blade. Rip to 5" wide, and shape the tip and bottom where it will attach to the hilt. I tried working with the protective film in place, but it was too cumbersome so most work was with it removed being careful not to scratch it too much.

Step 2: Shape the main blade

I used a band saw to give the tip a slight taper. Then routed a 45 degree angle chamfer bit at the front and back to give the blade a "sharp" edge. This edge is where the light leaks and appears to glow.

Step 3: Blade fuller

These "fullers" were cut 5" wide by 12" long. It was very difficult routing a 45 degree chamfer edge on these without burning the plastic or misshaping them. I tried making them identical since the blade would be transparent and irregularities would be visible.

Step 4: Light test

After testing with 3 blue LEDs I decided to light the main blade and each fuller individually for maximum brightness.

Step 5: Handle design

Using artistic license this part of the handle is from 3/4" maple on the bottom and 1/2" maple for the top. Routed a .66" slot for the blade to be sandwiched. This was mostly done freehand which is why it looks messy. Countersunk screws are used to secure the halves.

Thanks for all the votes! I'm happy to be a contest winner again.

After a month of looking at the sword I'll make some comments: 1. Use only yellow LEDs: Its a little too much orange. 2. Keep little kid hands off the blade: the smallest smudge gets amplified and are pretty visible from side angles. And the acrylic really holds onto dust due to static charges.
