Leather working tools: names, pictures and what each one is used for

Sharpness is the whole craft

Leather does not forgive a dull blade. A sharp knife parts the fibres cleanly and leaves an edge you can burnish to a shine. A dull one drags, tears and wanders off the line, and no amount of finishing recovers that edge.

This is why leatherworkers spend so much time on strops and stones, and why a cheap knife kept genuinely sharp outperforms an expensive one that has never been touched. The blade only has to be sharpened once properly; after that a few passes on a strop before each session keeps it there.

The same applies to punches, chisels and edge tools. A blunt punch crushes a hole rather than cutting it, and a crushed hole never looks right.

Strop before every session

Ten seconds on a loaded strop restores an edge that is only slightly tired. It is maintenance, not sharpening.

Learn to sharpen once, properly

A knife set up correctly on stones stays sharp with stropping alone for a long time.

Punches and chisels need sharpening too

Nobody expects it, and a blunt punch crushes leather instead of cutting it, leaving a ragged hole.

Cut on a self healing mat or poly board

A hard surface blunts the blade on the first stroke. Cutting into something slightly giving preserves the edge.

One firm pass, not several nervous ones

Repeated light strokes give a stepped ragged edge. Commit to the cut with a sharp blade and it goes cleanly.

Saddle stitching, and why it is done by hand

Hand saddle stitching uses two needles on one thread, passing through each hole from both sides. It produces a seam that will not unravel if a stitch is cut, because each stitch is independently locked. A machine lock stitch will run if it is damaged.

That is why quality leather goods are hand stitched, and it is not nostalgia. It is also why the holes are made first, with a pricking iron or stitching chisel, rather than punched by the needle. Marking then piercing gives even spacing and a consistent angle, which is what makes a stitch line look deliberate.

Mark, pierce, then stitch

Space the holes with a pricking iron or chisel first. A needle finding its own way gives a wandering line.

Two needles, one thread, both sides

That is the saddle stitch. Each stitch locks itself, so cutting one does not unravel the seam.

Keep the same needle passing first

Consistency of which needle goes through first is what makes the stitches lie at a uniform angle.

Wax the thread

Waxed linen or braided polyester resists abrasion and grips itself. Unwaxed thread frays and works loose.

Use a stitching pony

It holds the work so both hands are free for the two needles. Trying to hold it in your lap is why beginners give up.

Groove or crease the stitch line

A shallow groove lets the thread sit below the surface, protecting it from wear and making the line crisp.

Edges, which is where the quality shows

The single most visible difference between amateur and professional leatherwork is the edges. A raw cut edge looks unfinished no matter how good the stitching is.

The sequence is: trim it true, bevel both sides to take the sharp corner off, sand it smooth through the grits, dampen it, then burnish it hard until the fibres compress and shine. On vegetable tanned leather that produces a glassy edge that needs no dye at all. Chrome tanned leather will not burnish the same way and is usually painted with edge paint instead.

It takes minutes per edge and it is the thing people notice first.

Bevel both sides

An edge beveller takes the square corner off, which is what lets the edge round over when burnished.

Sand through the grits

Coarse to fine, the same discipline as any other finishing. Skipping grits leaves scratches that show in the shine.

Damp, then burnish hard

Water and friction compress the fibres. Heat from the friction is what sets the shine.

Veg tan burnishes, chrome tan does not

Know which leather you have. Chrome tanned edges are finished with edge paint in several thin coats.

Gum tragacanth or beeswax to finish

Either seals the burnished edge so it stays glossy rather than fluffing up again with handling.

What to buy first, in order

Stage one: cutting and a first project

A round or utility knife, a steel rule, a cutting mat, a poly cutting board, a strop, a wing divider, an awl and a pair of harness needles with waxed thread.

Stage two: stitching properly

A stitching chisel or pricking iron set, a maul, a stitching pony, an edge beveller, sanding sticks and a burnisher.

Stage three: finishing and hardware

Dye and applicators, gum tragacanth or edge paint, a hole punch set, a snap setter, rivet setters and a small anvil block.

Stage four: tooling and scale

A swivel knife, stamps, a granite slab, a skiving knife or machine, a splitter and a clicker press if you make in quantity.

Mistakes that show in the finished piece

Working with a dull blade

Everything else follows from this. A dragged edge cannot be burnished and a wandering cut cannot be squared up.

Leaving edges raw

The clearest sign of an unfinished piece. Bevel, sand, burnish, and it costs minutes.

Letting the needle find its own hole

The stitch line wanders and the angles vary. Mark and pierce first, every time.

Using the wrong leather for the job

Veg tan tools, moulds and burnishes. Chrome tan is soft and drapes and does neither. They are not interchangeable.

Dyeing without testing on a scrap

Leather takes dye unevenly and every hide differs. Test the colour and the number of coats on an offcut first.

Punching holes too close to an edge

The leather tears out under load. Keep a sensible margin, and more on anything that carries weight.

Over wetting leather

Soaking rather than casing makes it go dark, stretch and dry stiff and blotchy. Damp is what you want.

Setting hardware without support underneath

A snap or rivet set on a soft surface deforms. It needs a steel block behind it to set properly.

Looking after leatherworking tools

Strop, do not grind

Grinding a leather knife reshapes the bevel and takes ages to recover. A loaded strop maintains it indefinitely.

Keep steel away from damp leather

Casing leather is wet, and tools left on it rust and then mark the next piece with an iron stain.

Sharpen stitching chisels

They are cutting tools. A blunt chisel crushes and tears the holes rather than slitting them cleanly.

Wipe dye off tools immediately

Dried dye transfers to the next piece, usually onto something pale and expensive.

Store burnishers clean

Wax and gum build up and go hard, and then the burnisher drags instead of polishing.

Oil bare steel punches

They live in a drawer for months between uses, and a rusty punch pits the hole it cuts.

Frequently asked questions

What leather working tools do I need to start?

A sharp knife, a steel rule, a cutting mat, a strop, a wing divider, an awl, two harness needles and waxed thread. Add a stitching chisel, a stitching pony, an edge beveller and a burnisher and you can make a belt or a wallet properly.

What is saddle stitching and why is it better than machine stitching?

Two needles on one thread passing through each hole from both sides, so every stitch locks independently. If one stitch is cut, the seam holds. A machine lock stitch will unravel from a single cut, which is why quality goods are hand stitched.

What is the difference between veg tan and chrome tan leather?

Vegetable tanned leather is firm, takes tooling and moulding, and burnishes to a glassy edge. Chrome tanned is softer, drapes better and will not tool or burnish the same way, so its edges are finished with edge paint instead.

What is a pricking iron and how is it different from a stitching chisel?

A pricking iron marks the position and angle of each stitch without going all the way through, and you then pierce with an awl. A stitching chisel cuts right through in one action. Chisels are faster, irons give more control.

Why do my edges look rough and fluffy?

They have not been finished. The sequence is trim true, bevel both sides, sand through the grits, dampen, then burnish hard until the fibres compress and shine. On veg tan that alone gives a glassy edge.

What is skiving?

Thinning leather, usually at an edge or a fold, so a seam or a turnover is not bulky. Done with a skiving knife, a safety skiver or a machine, and it is what makes a folded edge lie flat instead of standing proud.

What is a stitching pony?

A clamp, often one you sit on, that holds the work upright so both hands are free for the two needles. Saddle stitching essentially requires one, and trying to hold the work in your lap is why beginners struggle.

Do I need a leather sewing machine?

Not to start, and not for most hand made goods. A heavy walking foot machine is worth it for volume or long seams, but hand saddle stitching is stronger and is the expected finish on quality work.

What thread should I use for leather?

Waxed linen or braided polyester in a weight suited to the leather. The wax resists abrasion and grips itself, so a stitch stays put. Ordinary sewing thread frays and works loose within months.

How do I stop dye looking patchy?

Test on an offcut from the same hide first, apply thin even coats rather than one heavy one, and keep the applicator moving in overlapping circles. Every hide takes dye differently, so the test piece is not optional.

What is casing leather?

Dampening it so it can be tooled or moulded. Damp, not soaked: over wetting makes leather go dark, stretch, and dry stiff and blotchy. It should feel cool and slightly darker, and return to colour as you work.

Why did the rivet pull out of my strap?

Either it was set too close to the edge, or it was set without a steel block behind it so the shank deformed instead of spreading properly. Both are common, and both mean the fixing was never really holding.
