This special addition can be added to one-handed and light melee weapons only, and prevents using two-handed blows with one-handed weapons.

An average-quality basket hilt adds 1 lb. and 2 gold pieces to the price of the weapon. Special materials, masterwork quality, and magical enhancements are applied separately from the base weapon. Treat the basket hilt as a dagger to determine masterwork, special material, and magical enhancement costs.

A basket hilt can be used to deal damage as a gauntlet of the same size. It offers a +2 circumstance bonus to attack rolls made to avoid being disarmed. For an additional 8 gp in cost and 5 lbs. in weight, the hilt can be made to lock as a locked gauntlet, increasing the circumstance bonus to +10.

Adding a basket hilt effectively prevents weapons from being thrown.
