Let's Make Cosplay: Mini Post: Specialty Edges for Blades

This is a mini blog post where I wanted to talk about how you could create a specialty edge on a blade. This is an extension off of the sheathed sword blog post and in this post I’ll walk you through how to do a wavy edge on a blade with aluminum tape.

This is tricky because you need a light tape so that it doesn’t rip the aluminum tape. Painter’s tape sticks too much and would be too hard to remove. Tape like masking tape, which doesn’t have as much adhesive, would be ideal.

What you should do is attach this tape to the blade’s edge and then draw out whatever wavy edge design that you want to have on the blade. Use an exacto knife and run it along the wavy lines you drew carefully so that you can pull off a piece to expose the first edge. Sand that one way. After you sand it, put the tape back over that section and peel off the tape from the other section. Sand that in a direction different to how you sanded the first section and you’ve got a specialty edge!
