Sabre

A deadly piece of Colorguard equipment that, if caught wrong, could physically injure any exposed and in-exposed part of your body, but what the hell, go ahead and attempt to catch a seven! It's pretty!

Undesirable No. 1: "Duuude, that sword is noooice! Could I give it a stab?"

You: " Sure, if you were planning on stabbing yourself!"

You: "Dammit! I got blood on my sabre again!
