Bell-Faced Hammer - not damage the surface of work (countersurface), slightly rounded (convex) face
Claw Hammer - Used to drive nails, wedges, and dowels. The claw pulls nails out of wood, and the face may be flat or rounded. It’s easier to drive the nails with the flat-face claw hammer but it leaves hammer marks on the surface when driving a nail flush with the surface.
Ball Peen Hammer - Has a flat face for striking and a spherical or hemispherical head for peening (rounding off) metal or rivets. It is used with chisels and punches.
Sledge Hammer - a heavy-duty tool used to drive posts or other large stakes. Don’t swing behind the head to drive the post, instead bring it up in front of you, and hammer the post/stake in front of you.

Saws

A

Backsaw - standard blade is 8-14in long with 11-14tpi (teeth per inch). Has a broad, flat blade, and a reinforced back edge. Used for cutting joints, especially miter joints and tenons.
Compass (keyhole) Saw - standard blade is 12-14in long with 7-8tpi. Cuts curves quickly in wood, plywood, or wallboard, and cuts holes for large-diameter pipes, vents, and plugs or switch boxes.
Coping Saw - narrow, flexible 6-3/4” blade attached to a U-shaped frame. Holders at each end of the frame can be rotated so you can cut at angles. Standard blades have 10-12tpi. Used for making irregular-shaped moldings fit together cleanly.
Drywall Saw - Long, narrow saw used to cut softer building materials, such as drywall. Has a fixed or retractable blade held to either a wood or plastic handle with thumb screws. Has a very sharp point, so that you can easily poke a hole to start your cut without drilling a starter hole. The jigsaw and spiral saw are power tools that are sometimes used in the same applications as a dry-wall saw.
Hacksaw - Saw is 8-16” with 14-32tpi. Has a sturdy frame and a pistol-grip handle. The blade is tightened using a wing nut and bolt. Used to cut through metal, e.g. nails, bolts, or pipe. When installing the blade, be sure that the teeth face away from, not toward, the saw handle. Hacksaws are designed to cut on the push stroke, not on the pull stroke.
Handsaws: Standard blade of the saw is 26” long. Makes a cut/ kerf that is slightly wider than the thickness of the saw blade itself
crosscut saw - 26” long with 8-14tpi
ripsaw - 26” long with 5-9tpi
