Guisarme

A guisarme is a two-handed, martial, melee weapon of the pole arm family.

Description
The basic guisarme is a weaponized pruning hook mounted on a long pole. It may or may not have a back spike. The convex edge (outside curve) is sharpened for slicing all the way up to the point of the hook. An average guisarme costs 9gp and weighs 12lbs (5.5kg). There are some other pole arms that incorporate the guisarme into their design.

Use
The guisarme is a pole arm so it requires two hands to wield. It is a reach weapon so it can strike targets 10 feet (3 meters) away but cannot be used against adjacent opponents. The hook may be used to attempt to trip an enemy or pull a rider off a mount. The back spike can be used for parrying or for a sideways swinging attack, but the guisarme is primarily an offensive slashing weapon. This weapon requires training to use and is classified as a martial weapon.
