Weapons that can be sold include the Pitchfork (3 food), Homemade/Tactical Spear (9 food), Stick Boot (6 food), and Bardiche (25 food). If you go to him with less than 3 food he gives you a Pool Cue for free.
If you tell him to Cool It!!! with the text flashing, he'll give your party a Bardiche.
The group meets a man wielding a homemade spear. Despite being a knife tied to a stick, it seems like it would be a really effective weapon.
