A kama is a light, exotic melee weapon typically used by monks.
The kama is similar to the sickle or a small scythe and bears a strong resemblance to a heavy pick but without the backside peen. It has a straight haft about the same size as a handaxe. The blade has less curvature than a sickle and starts out broader at the base before tapering to a sharp tip. An average kama costs 2gp and weighs 2lbs (0.9kg).
It takes special training to use the light kama effectively in melee combat, therefore it is considered an exotic weapon. The relatively long, curved blade allows the kama to be used for tip attacks. Unarmored monks can take full advantage of this quick, slashing weapon.
