Ok. A sickle costs 6 gp, weighs 2 lbs, and is a slashing weapon that does 1d4/1d6 damage, with a 20/x2 crit chance. A kama costs 2 gp, weighs 2 lbs, and is a slashing weapon that does 1d4/1d6 damage, with a 20/x2 crit chance. They may both be used to make trip attacks/dropped to avoid a counter-trip. The kama is exotic, and a special monk weapon. Except that monks are proficient with it by default. So, why, exactly does a kama exist?
