Basic Hand Tools That Start With L
Level
Type: Measuring / alignment tool
Checks whether a surface is perfectly horizontal or vertical using a liquid-filled vial with a centered bubble. Sizes range from a 9-inch torpedo level to a 4-foot bar. Used by carpenters, tilers, and plumbers.
Locking Pliers (Vise-Grips)
Type: Gripping / clamping hand tool
Clamp onto an object and stay locked without continuous hand pressure. A jaw-width screw pre-sets grip; a lever snaps them locked. Essential for rounded bolts, stripped nuts, and hands-free holding tasks.
Long-Nose Pliers (Needle-Nose Pliers)
Type: Gripping / bending hand tool
Long tapered jaws reach into tight spaces. Electricians bend wire loops around terminals; jewelers form wire; mechanics retrieve clips from deep inside engine bays. Many include a wire-cutting edge near the pivot.
Lineman’s Pliers
Type: Heavy-duty cutting / gripping hand tool
Larger and stronger than long-nose pliers. Cuts, twists, and grips heavy-gauge wire. Standard for electricians, power line workers, and cable technicians.
Leather Punch
Type: Piercing hand tool
A rotating barrel selects hole size; pressing through leather, rubber, or canvas creates clean round holes. Used by belt makers, saddle makers, shoemakers, and campers repairing straps.
Linoleum Knife
Type: Cutting hand tool
Hooked, curved blade scores and slices vinyl, rubber, foam, and sheet flooring. The hook keeps cuts tracking straight without wandering. Standard for flooring installers on edge and corner cuts.
Lumber Crayon (Keel)
Type: Marking tool
Thick wax-based crayon marks clearly on rough, wet, or dark surfaces — wood, concrete, stone, metal. Used by framers, masons, and concrete workers. Available in multiple colors for job-site coding.
Lead Pencil (Carpenter’s Pencil)
Type: Marking tool
Flat, oval shape prevents rolling on sloped surfaces. Wide flat lead marks rough wood grain; sharpens to a fine point or chisel edge. Used by woodworkers, cabinet makers, and carpenters for layout lines.
Latch Hook
Type: Craft / textile hand tool
Small hooked tool with a hinged latch pulls yarn loops through mesh or canvas backing. Used in rug making and fiber craft. The latch prevents yarn slipping back during pulling.
Letter Stamps (Metal Stamp Set)

Lacing Needle
Type: Leather / textile hand tool
A large, blunt needle with a wide eye for threading lacing cord through pre-punched holes in leather, canvas, or heavy fabric. Used by leather workers, sailmakers, and cobblers.
Linishing Belt (Hand File Belt)

Mechanic Tools That Start With L
Lug Wrench
Type: Automotive fastening tool
Removes and tightens wheel lug nuts. The cross-pattern version gives far more torque than the L-shape. Every car kit includes one; shops use impact wrenches for speed.
Safety tip: Loosen lug nuts before jacking the car — not after.
Lock Nut Remover (Bolt Extractor)
