A good tool head outlasts dozens of handles. Vintage hammers, axes, chisels, and files with cracked, loose, or broken handles are not garbage — they are tools waiting for a $5 to $15 handle replacement. The metal head is the expensive, irreplaceable part. The handle is a consumable that anyone can replace with basic tools and 30 minutes of work. Here is how to replace handles on the most common hand tools.

Hand Tool Handle Replacement

Hammer Handle Replacement

A loose hammer head is dangerous. It can fly off the handle mid-swing and strike anything nearby. If the head wobbles on the handle at all, stop using it immediately.

Removing the Old Handle

Clamp the hammer head in a vise with the handle pointing up
Drill several 3/8-inch holes through the old handle stub inside the eye (the opening in the head where the handle sits) to weaken the wood
Drive the remaining wood out through the bottom of the eye using a punch or drift. Hit from the top down — hammer heads are tapered from top to bottom, so the handle stub exits from the wider bottom opening.
Clean the eye completely. Remove all wood remnants, old wedges, and debris.

Fitting the New Handle

Replacement hammer handles are available at any hardware store for $5 to $12. Buy hickory — it is the standard handle wood for hammers because it absorbs shock, bends without breaking, and has been proven for centuries.

The new handle comes oversized to fit a range of hammer heads. Test-fit the handle in the eye. It should enter about halfway before stopping.
Shave the handle end with a rasp, wood rasp, or belt sander to fit the eye. Remove material gradually, testing frequently. The handle should press into the eye with firm hand pressure and stop about 1/4 inch from the shoulder (the flared area below the head).
Mark the outline of the eye on the handle top for the kerf cut.

Seating and Wedging

Cut a kerf (thin saw cut) down the center of the handle end, approximately 2/3 the depth of the eye. This kerf accepts the wedge that expands the handle inside the eye.
Drive the handle fully into the eye by striking the bottom of the handle against a solid surface (not by hitting the head). The head should seat firmly on the handle shoulder.
Insert the wooden wedge (included with most replacement handles) into the kerf. Drive it in with a hammer until it is firmly seated. Cut the wedge flush with a hand saw.
For extra security, drive a small metal wedge across the wooden wedge at 90 degrees. This expands the handle in both directions and locks it permanently.
Sand the handle end flush with the hammer head.

Finishing

Apply boiled linseed oil to the entire handle — two coats, wiped on and allowed to absorb for 20 minutes between coats. Linseed oil penetrates the wood grain, prevents drying and cracking, and provides grip. Do not use varnish or polyurethane — they create a slick surface that slips when your hands sweat.

Axe Handle Replacement

The process is nearly identical to hammer handle replacement but scaled up. Axe eyes are larger, the handles are longer (28 to 36 inches for a felling axe), and the fitting requires more material removal.

Remove the old handle by drilling out the wood in the eye and driving it through.
Fit the new hickory handle into the eye. Axe handles are shaped with a pronounced curve — orient the handle so the blade edge and the curve sweep are on the same side.
Cut the kerf deeper (3 to 4 inches for a standard axe eye).
Seat the head by driving the handle butt against a hard surface.
Insert the wood wedge, then a steel cross wedge.
Some axe users soak the head end of the handle in linseed oil for 24 hours before fitting. The oil swells the wood slightly and prevents the head from loosening.

Axe handle replacement is one of the most satisfying tool maintenance tasks. A worn axe with a fresh hickory handle and a re-ground edge works better than a new axe from the hardware store.

Chisel Handle Replacement

Chisels with wooden handles eventually split from mallet strikes. The tang (the pointed steel spike extending from the blade) sits inside the handle. Replacement is simple:

Pull the old handle off. If stuck, clamp the blade in a vise (protect the blade edge with leather or wood) and twist the handle off. Or drill it out.
Buy or turn a replacement handle from hardwood — beech, maple, or ash. Chisel handle blanks are available for $3 to $8 from woodworking suppliers. Or turn one on a lathe from any dense hardwood scrap.
Drill a pilot hole in the center of the new handle, sized slightly smaller than the tang diameter and 3/4 the tang length.
Drive the tang into the handle by striking the handle butt on a hard surface. The tang splits the wood grain internally, creating a tight press fit.
For added security, fill the pilot hole with epoxy before driving the tang in. The epoxy bonds the tang to the handle permanently.

A ferrule (the brass or steel ring at the base of the handle) prevents the handle from splitting at the tang entry point. If your replacement handle does not have one, press a short section of copper pipe over the handle end before driving the tang.

File Handle Replacement

Files should always have a handle. The bare tang is a spike that will impale your hand when the file catches. Replacement file handles are the cheapest tool fix — $2 to $4 each.

Pull the old handle off (if present). Grip the handle and tap the ferrule end against the workbench edge.
Select a handle sized for the file. Handles come in small, medium, and large to match file tang sizes.
Drill a pilot hole in the handle, slightly smaller than the tang.
Push the tang into the pilot hole. Seat it by tapping the handle butt against the bench or striking it with a mallet.

That is the entire process. Buy a bag of assorted file handles ($10 for a dozen) and put one on every file in the shop. No exceptions.

Screwdriver Handle Replacement

Most modern screwdrivers have injection-molded plastic or rubber handles that cannot be replaced. The tool is essentially disposable when the handle cracks. Vintage screwdrivers with wood handles can be re-handled using the same technique as chisels — drill a pilot hole and drive the tang in.

For plastic-handled screwdrivers where the handle has split but the shaft is still good, some people repair with epoxy or heat-shrink tubing. This works in a pinch but a new screwdriver is $8 and has a fresh, properly fitting handle.

Where to Find Replacement Handles

Hardware stores: Most carry hammer handles and a few axe handles in hickory
Online: Amazon, Lee Valley, and Garrett Wade have handles for hammers, axes, chisels, files, and mallets. Lee Valley ($8 to $15) sells precision-shaped handles in multiple wood species.
Make your own: A lathe and a blank of hard maple or hickory produces custom handles matched to your hand size and grip. This is excellent lathe practice and produces a handle that fits you perfectly.

Bottom Line

Never throw away a tool because the handle is broken. A $5 hickory handle, a wedge, and 30 minutes of fitting restores a hammer, axe, or chisel to full service. Keep replacement handles in stock — two hammer handles, a couple of chisel blanks, and a bag of file handles covers most shop needs. The heads last generations when the handles are treated as the replaceable components they are.
