Did you mean One-Handed Melee Weapons perhaps?
A one-handed weapon can be used in either the primary hand or the off hand. Add the wielder’s Strength bonus to damage rolls for melee attacks with a one-handed weapon if it’s used in the primary hand, or 1/2 his or her Strength bonus if it’s used in the off hand. If a one-handed weapon is wielded with two hands during melee combat, add 1-1/2 times the character’s Strength bonus to damage rolls.
An example for a one-handed weapon is the Longsword.
