It seems a trinket of a blade, but I admit I am also intrigued by its utility.

[ He says that 'cause he got one too! Xenk already has a scabbard at his waist with a proper longsword, but more swords are always better. ]

If the enchantment holds, one would assume so. Though in its current state, perhaps not. [ He holds the blade over, turning it in his hand. ] Does it require attunement...?
