In German archeological literature, the so-called Knollenknaufschwert was a Celtic sword of the Late Hallstatt or early La Tène periods. They were exclusively thrusting swords or rapiers with squared-shaped cross-sections. They were also narrow and extremely long, usually an overall length of 86 to 105 centimeters and a blade length of 73 to 83 centimeters.

The Knollenknaufschwert had iron beads attached to the tang, two on the sword guard and four at the pommel, crowning the hilt. These long rapiers had scabbards constructed from two overlapping iron strips. Some historians suggest that warriors did not use them in combat but only for fencing, duels, or ceremonial purposes.
