Improvised

SickleSuffice it to say, that water bottle was successfully harvested.

It is surprising how many unusual weapons feature in historical artwork and in combat treatises. Sickles, scythes, clubs, grain threshing flails and logs for example.

Although it is clear that a nobleman was highly unlikely to defend himself with a sickle when many countries allowed free carry of swords or at least knives and quarterstaves, but as I mentioned in one response video, these techniques must have come from somewhere to pass over to wealthy gentlemen and I theorised that peasants who were forced to learn such cheap self defence would be the answer.
