This is a Lego technique I came up some time ago. (Didn't realize...."Spaztastic the Diabolical" already posted a similar technique before me.)
About this creation
This technique only works when your minifigure is holding a triangular shield. You can tilt it in such a way as to make a crevice for the sword. This allows your minifigure to hold multiple weapons or items. It is useful in Castle and Medieval scenes. You are welcomed to use this technique, but I would greatly appreciate acknowledgements! Thanks!
This is just a test animation that I added at the last minute:
Oh, hey! I found me! Nice stop-motion. I tend to do searches on simple designs, but with only two creations as such, it's never been a problem. But still, I still think it's cool that you do this regardless of accidental plagiarism. I think it just adds another layer of sophistication to a build.
