The "novelty junk" in CLXV - Swords Swordsmas Special has the hilt and blade switched places and lengths, which makes it seem useless. But, this design inadvertently turns it into a boar spear, which have crossguards just below the spearhead because boars have a tendency to try Taking You with Me maneuvers against hunters. It's also ideal for performing a Mordhaunote German for "murder-strike" — that is, grabbing the sword by the blade and using the hilt as a mace, which tends to render armor ineffective, and is banned in sporting combat because it's a move intended for killing and only killing. In other words, this reverse sword is actually a quite practical design.
How do merblades walk? They have a sword hilt from the waist down, yet they seem to be able to move just fine, especially Sharp Sharply the merblade announcer.
It could be achieved via merblades hopping around.
