Leather Edge Bevelling Explained
Quick answer: Edge bevelling removes the sharp corner from a cut leather edge with an edge beveller. For a rounded burnished finish, bevel the visible corners where the construction calls for it, after cutting and before sanding. Choose a size that suits the leather thickness and the amount you want to remove; a thin lining or an edge that will be painted may need a different approach.
Leather edge bevelling removes a thin strip from a cut corner before sanding and burnishing. This guide explains how to bevel leather edges for a rounded finish, choose the size of edge beveller and keep the cut controlled.
This guide explains what bevelling does, why it matters, and how to do it correctly.
What an edge beveller does
A leather edge beveller is a small cutting tool with a V-shaped or U-shaped groove at the tip. When drawn along the corner of a leather edge, it lifts and removes a thin strip of material from that corner — leaving a chamfered profile rather than a sharp right angle.
The result is a slightly rounded corner, on both the top and bottom edges of the leather. This new profile is what makes burnishing effective. When compound is applied and friction is worked into the edge with a burnisher, the bevelled corner compresses into a smooth, rounded shape. Without the bevel, the sharp square corner resists this compression and the edge tends to look flat, stiff, and less finished regardless of how carefully the rest of the process is done.
Bevelling also removes the layer of leather fibres at the corner that would otherwise be the first to fray and wear in use. A bevelled edge holds up significantly better over time than an unbevelled one.
When to bevel
The bevel should be applied after the edge is cut and before sanding. The sequence is: cut, bevel, sand, apply burnishing compound, burnish. Doing the bevel after sanding means you will need to sand again anyway to smooth the freshly cut bevel — so the order matters.
Bevel both the top edge (grain side) and the bottom edge (flesh side) of the leather. Both corners benefit from the treatment, and both will be visible in the finished piece.
Choosing the right beveller size
Edge bevellers come in numbered sizes. A smaller number removes less material — it is suited to thinner leather and finer work where a lighter bevel is appropriate. A larger number removes more material and suits heavier leather. Kevin Lee edge bevellers, which we stock, are a reliable starting point across this range.
Choose the amount of leather you want to remove, not a number in isolation. Beveller size numbers are not a reliable comparison between different makers. Start with a light cut on an offcut of the same leather and check the remaining edge profile. Thin or layered work may need very little removed; a thicker edge does not automatically need the largest tool.
An oversized beveller on thin leather removes too much material and leaves a noticeably chamfered, angular look that can detract from the piece. An undersized beveller on heavy leather leaves a bevel that is too slight to be effective.
How to use an edge beveller
Draw the beveller along the corner of the edge in a single firm, consistent stroke. Hold the tool at the working angle intended by its design and keep that angle consistent through the cut. The blade should cut cleanly and lift a thin strip in a continuous curl.
If the beveller is dragging rather than cutting, the blade needs stropping. An edge beveller should cut with light, deliberate pressure rather than requiring force. A well-maintained blade makes a noticeable difference to the quality and ease of the bevel cut.
Stropping the beveller blade
Edge beveller blades dull with use, particularly on firm vegetable-tanned leather. A leather strop loaded with a small amount of polishing compound, used regularly, keeps the blade in cutting condition. A few strokes on the strop are usually enough. This is the same principle as stropping any small edge tool — frequent light maintenance is better than waiting until the blade is noticeably dull.
If the bevel cut has remained rough despite stropping, or if the blade tip has chipped, the blade or the whole tool may need replacing.
Checking the result
After bevelling, run a fingertip along the corner. The corner should feel smooth and slightly chamfered — not sharp, not ragged. Hold the edge up to the light. The bevel should be consistent along the full length without skips, variations in depth, or missed sections. Re-run the tool over any areas that need attention before moving to the sanding stage.

Frequently asked questions
What does an edge beveller do in leatherwork?
An edge beveller removes the sharp corner from the top and bottom edges of cut leather. This creates a chamfered profile on each side of the edge that allows burnishing compound and friction to compress the leather into a smooth, rounded shape. Without it, the edge stays flat and square regardless of how much compound is applied. Bevelling also removes the exposed fibres at the corner that would otherwise be the first to fray in use.
When should you bevel leather edges?
After cutting and before sanding. The sequence is: cut, bevel, sand, apply burnishing compound, burnish. Doing the bevel before sanding means the fresh bevel surfaces are then sanded smooth in the same pass. Bevelling after sanding simply means you need to sand again — and reversing the order creates extra work without any benefit.
What size edge beveller should I use?
Use the smallest cut that gives the edge the shape you want. Check the maker’s actual cutting size and test it on the same leather before working on the piece. A size number by itself does not establish a leather-thickness range. Stop if the tool removes too much from the face or leaves too little edge to finish.
Do you bevel both sides of leather edges?
For a rounded, burnished single-layer edge that will be visible from both sides, normally yes — bevel the grain-side and flesh-side corners. On lined or layered work, bevel the exposed outer corners appropriate to the finished construction. Remove only as much as the leather thickness and intended finish need.
