Lance rest (3.5e Equipment)
From D&D Wiki
A lance rest is a metal flange that is typically attached to the right side of an armour, just under the armpit. A lance costs +10 gp, weights + 1 lbs and gives a +1 bonus to Attack rolls when used with a lance during a charge, but gives a -1 bonus to Attack rolls when it is used in other circumstances. The lance rest is typically bolted to the side of the breastplate or secured through the use of metal tabs known as staples. The majority of the time, the lance rest is hinged so that it can be folded upward to prevent an obstruction of the wearer's sword arm once the lance is intended to be used differently from a charge or has been abandoned in favor of another weapon. You may fold upward or downward a lance rest as a move action, or (if your base attack bonus is +1 or higher) as a free action as part of movement. Without the Quick Draw feat, you can fold upward or downward a lance rest as a standard action.
