For your Girlfriend, Self-defense claws.

I changed my mind a lot on this build, some things got in the way today, anyway we ended up with razor claws nonetheless. It was a bad day today so the video was kinda thrown together. I was also thinking it might be easier for a girl to snap off a razor than beat wire into a claw, but on that note* I'm fairly confident that a wire claw will work out, if you bend it and cold forge it. I did a Karambit like that, I don't know how I forgot. I ended up using the hot glue alone to secure the razors because the super glue and cloves wasn't really worth the mess or resource. And it held well. Feel free to use whatever epoxy that you want including J-B Weld. The biggest part to take from this guide is the knuckle duster shape cut in half with some razor claws in between, it becomes a little stealth weapon even though it doesn't look like all that big of a deal.
