Axe and Hatchet

Part of Woodworking

The axe is the oldest and most essential woodworking tool. With nothing else, you can fell trees, shape timber, split firewood, and carve joints. Understanding how to select, sharpen, and swing an axe safely is foundational to every other woodworking skill.

Axe vs. Hatchet

The difference is simple: a hatchet is used one-handed, an axe two-handed. This changes everything about when and how you use each.

Feature	Hatchet	Axe
Handle length	12-18 inches (30-45 cm)	24-36 inches (60-90 cm)
Head weight	1-2 lbs (0.5-0.9 kg)	2.5-5 lbs (1.1-2.3 kg)
Grip	One hand	Two hands
Best for	Limbing, carving, splitting kindling, camp tasks	Felling, bucking, splitting, hewing
Control	High precision, low power	High power, moderate precision
Carry	On a belt or in a pack	Over the shoulder or in a vehicle

Which to Learn First

Start with a hatchet. It teaches edge control, swing mechanics, and sharpening without the danger and fatigue of a full-size axe. Every technique transfers directly.

Head Geometry

The shape of the axe head determines what it does well.

Felling Axe

• Bit (cutting edge): Thin, slightly convex
• Cheeks: Narrow, slender profile
• Purpose: Deep penetration into standing wood
• Weight: 2.5-3.5 lbs
• Characteristics: Cuts across grain efficiently. The thin profile slides into the cut easily. Not suitable for splitting — it gets stuck.

Splitting Axe/Maul

• Bit: Thick, wedge-shaped
• Cheeks: Wide, heavy, convex
• Purpose: Forces wood apart along the grain
• Weight: 4-8 lbs (mauls are heavier)
• Characteristics: Does not cut — it wedges. The thick cheeks push the wood fibers apart. Glances off if used for felling (too thick to penetrate).

Broad Axe

• Bit: Wide, flat on one side (single bevel)
• Cheeks: Flat on the hewing side, offset handle
• Purpose: Hewing flat surfaces on logs (making beams)
• Weight: 4-7 lbs
• Characteristics: Used like a giant chisel, cutting along the grain. The flat side rides against the surface you are creating. The handle is offset so your knuckles clear the work.

Carving Hatchet

• Bit: Short, very sharp, slightly curved
• Cheeks: Narrow
• Purpose: Shaping spoons, bowls, small items
• Weight: 1-1.5 lbs
• Characteristics: Short handle allows precise control. Often has a beard (extension of the bit below the eye) that lets you choke up for very fine work.

Handle (Haft) Selection

The handle matters as much as the head. A poor handle transmits shock to your hands, breaks at the wrong moment, or throws the head.

Wood Selection

Species	Quality	Notes
Hickory	Best	Gold standard. Absorbs shock, incredibly tough, available in long straight billets
Ash	Excellent	Lighter than hickory, nearly as shock-resistant. Traditional European choice
White oak	Good	Stiffer than hickory/ash, transmits more shock. Adequate for light-duty
Hard maple	Fair	Stiff, does not absorb shock well. Better for mallets than axes

Grain Requirements

This is the most important factor in handle durability:

• Grain must run straight from end to end. Hold the billet up and sight down it. If the grain runs diagonally, the handle will break at that point under impact.
• Growth rings should be parallel to the bit (perpendicular to the direction of swing). This orientation is strongest against the bending forces of chopping.
• No knots anywhere in the handle. A knot is a guaranteed failure point.
• No run-out (grain that exits the side of the handle). Run-out creates a weak cross-grain section.

Grain Orientation Is Not Optional

A handle with diagonal grain or visible run-out WILL break. It is not a question of if, but when. An axe head flying off a broken handle is a life-threatening event. Inspect every handle before fitting.

Shaping the Handle

If you are making a handle from a split billet (not buying one):

1. Split, do not saw: A split billet follows the grain exactly, guaranteeing straight grain. A sawn billet may cross the grain invisibly.
2. Rough shape with a hatchet: Bring the billet to approximate profile — swell at the base (knob), slim through the grip, wider at the shoulder near the head.
3. Refine with a drawknife or spokeshave: Smooth the curves, create an oval cross-section (not round — oval gives you rotational reference so you know your edge orientation without looking).
4. Finish with a rasp and sandpaper: Smooth enough to prevent blisters but not so slick that it is hard to grip. Do not varnish or paint the grip area — bare wood gives the best grip.

Eye Fitting and Wedging

The eye is the hole in the axe head through which the handle passes. Fitting the handle to the eye is critical.

Fitting Steps

1. Shape the handle shoulder to match the eye shape. Most eyes are oval, wider in one dimension. The handle shoulder must match this profile exactly.
2. Trial fit: Push the handle into the eye from below. It should be snug by hand pressure for the last 1-2 inches. If you can push it all the way through by hand, the fit is too loose — reshape the shoulder.
3. Seat the head: With the handle pointing up, strike the butt end of the handle with a mallet. The head slides down the handle and seats onto the shoulder. Continue until the head is fully seated and the handle protrudes 1/4 to 1/2 inch above the eye.
4. Saw a kerf: Cut a slot in the protruding handle end, centered, running in the direction of the eye’s narrow dimension. Depth should be about 2/3 the depth of the eye.
5. Drive the wedge: Use a hardwood wedge slightly wider than the kerf at its base. Drive it into the kerf with a mallet. This expands the handle inside the eye, locking the head in place.
6. Trim flush: Cut the excess handle and wedge flush with the top of the eye.

Metal Wedge (Optional, Added Security)

After the wooden wedge is seated, some makers drive a small metal wedge at 90 degrees to the wooden wedge. This cross-wedging locks the head from all directions. Not strictly necessary if the wooden wedge fit is good, but adds insurance.

Linseed Oil for the Eye

After fitting, pour a small amount of boiled linseed oil into the eye from above. It soaks into the end grain of the handle, causing it to swell and tighten the fit further. Repeat annually.

Sharpening

A sharp axe is safer than a dull one. A dull axe bounces and glances; a sharp one bites and holds. Sharpen frequently.

Profile: Convex Bevel

An axe should have a convex (rounded) bevel, not a flat bevel like a chisel. The convex shape:

• Resists chipping better than a thin flat bevel
• Provides clearance behind the edge so it does not get stuck
• Self-clears chips during the cut

Sharpening Steps

1. File first (if the edge is nicked or very dull):

   • Clamp the axe head or brace it securely
   • Use a 10-inch mill bastard file
   • File from the cheek toward the edge, lifting on the return stroke (files only cut on the push stroke)
   • Maintain the convex profile by rocking the file slightly as you stroke
   • Work both sides equally, counting strokes to keep the bevel centered
   • Stop when you can feel a slight burr on the opposite side

2. Stone second (refine the edge):

   • Use a coarse/fine combination stone or a puck-shaped axe stone
   • Apply oil or water (depending on stone type)
   • Work in circular motions along the bevel, maintaining the convex profile
   • Start coarse side, flip to fine when scratch marks are uniform
   • Work both sides equally
   • The edge is sharp when it easily shaves hair from your forearm or catches a fingernail without sliding

Maintaining the Edge

• Strop on leather or a piece of cardboard between sharpenings for quick touch-ups
• Never chop into dirt, rock, or frozen ground — one strike on a hidden stone can ruin an edge
• Sheathe the axe when not in use. A bare edge bumping against anything dulls or chips it.
• Light rust can be removed with fine steel wool and oil. Heavy rust needs filing.

Safe Swinging Mechanics

Two-Handed Axe

1. Stance: Feet shoulder-width apart, target directly in front. For felling: stand with feet offset so a missed swing passes between your legs, not into your shin.
2. Grip: Dominant hand near the head (slide hand), other hand at the butt (anchor hand). As you swing, the slide hand slides down to meet the anchor hand.
3. Swing arc: Raise the axe over your dominant shoulder. The swing travels in a smooth arc — the axe head accelerates through gravity and shoulder rotation. Do not muscle it — let the weight of the head do the work.
4. Contact: The edge should meet the wood at 30-45 degrees for chopping across the grain. Striking perpendicular to the grain buries the axe and wastes energy.
5. Follow-through: Do not try to stop the axe on contact. Let it follow through the cut. Deceleration comes from the wood, not your arms.

One-Handed Hatchet

• Chop with controlled, shorter swings
• Keep your other hand and body parts clear of the swing path
• When splitting kindling: hold the piece of wood at the top, place the hatchet edge on the far end of the wood, then bring both down together onto a chopping block. This keeps your fingers away from the edge.

The Number One Axe Injury

Glancing blows to the shin or foot. This happens when the axe misses the target or passes through thin wood. Always stand so that a miss drives the axe into the ground or the chopping block, not your body. Never chop while kneeling.

Re-Hafting a Loose Head

A loose head is dangerous. It throws the head during the swing.

1. Remove the old handle: Drive the handle stub out from below (through the narrow end of the eye). Drill out the old wedge if it will not come free.
2. Clean the eye: Remove all old wood fragments, rust, and debris.
3. Fit the new handle: Follow the eye-fitting process above. The new handle must fit snugly.
4. Check before heavy use: After fitting, swing the axe gently into a log a few times. If the head shifts at all, re-seat it. Never use an axe with any play between head and handle.

Quick Field Fix

If the head loosens in the field and you cannot re-haft immediately:

• Soak the head end of the handle in water for several hours. The wood swells and tightens temporarily.
• This is a temporary fix only. Water-swelling loosens and re-tightens repeatedly and will eventually enlarge the eye permanently. Re-haft properly as soon as possible.

Axe and Hatchet — At a Glance

• Hatchet for one-hand precision work; axe for two-hand power work
• Match head geometry to task: thin for felling, thick wedge for splitting, flat-sided for hewing
• Handle grain must run straight end-to-end, rings perpendicular to the bit — no exceptions
• Fit the eye tight, wedge to expand, apply linseed oil
• Sharpen to a convex bevel: file for shaping, stone for refining
• Swing with gravity, not muscle. Let the head weight do the work.
• A sharp axe is a safe axe. A loose head is a lethal hazard. Check before every use.
