Sword

A sword is a weapon used mostly by humans, but Smurfs are also seen wielding them, if not always actually using them. Swords used by Smurfs are either wooden or use duller edges that are mostly used for non-lethal combat or cutting through ropes and shrubbery due to the perception that Smurf culture considers killing to be a taboo.

Various Series Usage
There are several different fanon series which have characters using one or more swords.

Empath: The Luckiest Smurf
In the EMPATH: The Luckiest Smurf story series, Duncan McSmurf is the only Smurf in the village who is a master swordsman, capable of wielding and using all kinds of swords, both single-handed and two-handed varieties. Carpenter crafts the wooden swords while Smithy forges the metal ones, with Duncan testing them to see if they are durable enough. Tapper in particular owns the Sword Of Ailill, a family heirloom that has a remarkably sharp blade for a Smurf sword and is said to imbue the fighting spirit of an Ailill into even a pacifist among their clan.
