Sam, you've reminded of me of an idea I had a while back. Imagine a bathroom where normal fixtures are also forged weapons. Like a toilet plunger with a decorative mace attached to the handle, unscrew the rubber plunger, and you've got a battle ready mace. Plus, it would look better than the normal ones, use some nice stained hickory for the handle.
A forged towel rack, spiked ends. A nice wooden shower curtain, but forged speartips on the ends, not too sharp, but still a potential weapon. I just like the idea that they are function, artistic, and if needed, deadly. Yet, most folks wouldn't see them as overt weapons.
Plus, during a home invasion you'de be ready, in the shower, on the toilet, or while drying your hands. We all know, shit happens in the bathroom! All these things could look good with your TP holder.
Nice TP holder by the way!
