All of these activities are, of course, done with simulated weapons.
Heavy combat uses rattan weapons, and rapier combat uses modified modern fencing equipment.
Isenfir has an active corps of rapier fighters who get together each week to practice and hone their skills in the Art of Defence. New people are encouraged to come out and learn about period fencing, and there is some amount of loaner equipment available when you first get started. You should wear long pants and sleeves, and men should bring a cup.
