Some carpenters and other users prefer this, as they can begin a stroke by gripping the hammer towards the center of the handle, and allow the handle to slide through their hand as they swing. Wooden hammers have relatively little grip, which can allow the hammer to slide from the hand. Low quality rubber handled hammers are known to often separate from the hammer and cause injury to the user. Steel and fiberglass handles generally have rubber or rubber-like grips for increased comfort and better grip. Fiberglass is becoming a common handle material due to its increased durability and shock and vibration absorbing capabilities. Single piece steel hammers are available and are the most durable, but typically do not absorb the shock of the hammer blows well. Broken wooden handles can often be replaced. Wooden handles are usually made of hickory, an extremely tough wood, but can be readily broken if one misses the nail and hits the handle instead. For pulling nails, a wooden block can be placed under the head of the hammer close to the nail to increase leverage. It does not have as much leverage for removing nails as a curved claw hammer when using the face of the claw as the fulcrum, but the handle can be pulled to the side to greatly increase leverage by using a very short fulcrum. The straight claw serves the dual purpose of removing nails and acting as a crow bar to pry apart (rip) lumber. This allows the nail to be placed and driven quickly with just one hand. Some framing hammers have a magnetized slot along the top edge of the striking surface to hold a nail. A hammer with a smooth striking surface is known as a finishing hammer and is used where marring of the wood is to be avoided for cosmetic reasons. ![]() Since the frame typically will not be seen on the finished house, the inevitable marring of wood surfaces by the milled hammer face is not an issue. The raised marks on the head of the hammer grip this grid, which helps to prevent the hammer from sliding off the nail head when striking a nail. Nails typically used for framing have a grid of intersecting raised metal lines on the head of the nail. ![]() The milled face of the head consists of a waffle-like grid of small four sided pyramids.
