Choosing a Work Surface and Cutting Mat for Leather

ByPeter Joeseph 'Briefcase Maker' Kalafatis

What sits under the leather decides how the knife, the punch and the hammer behave.

A leather bench is three or four surfaces stacked on top of each other, and each one does a different job: one takes the knife, one takes the punch, one takes the hammer, and the bench under all of them has to stand still while you lean your weight into it. People buy the knife first and worry about the surface later. That order is backward. A sharp blade on the wrong board drags, wanders and goes dull, and a good punch on a bouncing table leaves holes that walk. Weaver Leather Supply’s shop video on its main work table is a good place to start, since the page says the maker in it walks through the table and his preferred cutting surface.

My bias, up front. I make briefcases out of thick English bridle, alone, and the Maker page on this site says the new workshop is going up in East Setauket and “the bench moves with me.” So I care about benches. The answers below lean on the toolmakers and on working makers who argue about this on the trade forums, and they get named where they show up.

How high and how solid should the bench be?

Below the elbow, and heavy enough that a hammer blow stays in the leather.

Nobody publishes one correct height, but the makers who talk about it land in the same place. In a leatherworker.net thread on building a work bench, the original poster had gathered that the right position is just below the elbow. Another member, Rustwa, sets his at about 40 inches by taking his floor-to-elbow distance and knocking a couple of inches off. kgg measures from the floor to the top of his belt buckle, in the shoes he works in. That last detail is the one people skip. Measure in bare feet and the bench is wrong the first morning you stand at it in boots.

Lower has its own fans. In an older thread on layout and cutting tables, Drac keeps his table low so he can put a foot down for stability, and daviD A Morris likes his just below waist height. Cutting a long line wants your shoulder over the work. Fine stitching wants it closer to your eyes. My opinion: one height won’t do both, and that’s why so many shops end up with two tables.

Solid matters more than height. A table that rocks when you hit a punch eats the force you meant for the leather, and the hole comes out ragged. In that same layout thread, mulefool says his polyethylene-topped tables are solid enough to set rivets without much bounce, and esantoro warns that his folding tables are no good for heavy pounding.

One more thing about size. In the work bench thread, Matt S says his bench is too shallow for breaking down hides and needs to be twice as deep. A whole bend of bridle is a big, stiff thing. Mine get laid out flat and looked over before a knife comes near them, because I check every hide when it arrives and send flawed leather back. That takes room, the kind a kitchen table doesn’t have.

Self-healing mat or poly board for cutting?

The mat suits a rolling blade. The board suits a heavy knife and a heavy hand.

A self-healing mat is layered PVC. The Creative Curator’s piece on how self-healing mats work explains that the surface is built from tiny particles pressed together, so a cut gets absorbed among them instead of leaving a trench. Pet Hardware’s listing for a large gridded self-healing mat sells it for webbing, collars, bags and wallets, and says the closing surface helps the blade last.

A poly board is a slab of polyethylene. The Tandy poly cutting board on that same retailer’s site is listed at 13 mm thick, for cutting, punching and stamping, and the listing says it absorbs shock. Maclace Leather’s HDPE board makes a similar pitch, that the plastic absorbs impact and keeps blades sharper.

The makers split along the line you’d guess. In a leatherworker.net thread on cutting surfaces, alpha2 uses a self-healing mat for wheel cutting and a poly board for severe cutting, and says tight cuts can mess up a mat. LumpenDoodle2 gave the green mats up because, in his words, “they seemed to grip my knife blade”, especially a round knife. Others in the thread swear by their Fiskars mat.

My opinion: thick bridle is the problem child here. It takes pressure, and a knife leaning on a soft mat sinks. A rotary cutter rolls over a mat happily, and a round knife pushed through a stiff bend wants something harder that won’t grab. Whatever you pick, the Creative Curator page lists the ways mats die: heat, dull blades, cutting the same line over and over, and storing them rolled. Keep it flat.

What goes under a punch or a stitching chisel?

Something the steel can sink into a little, and nothing that bounces.

Punching is where surfaces get argued hardest, and it matters to me more than cutting does. I pre-punch every stitch hole on a briefcase and line them up before a needle goes in, because thick work won’t stitch any other way. That’s covered in the post on punching stitch holes in thick bridle. Every one of those holes lands on whatever is under the leather.

Rubber is the classic answer. Weaver’s Silent Poundo Board is a slightly tacky rubber board, and the page says it absorbs pounding concussion and sound and keeps punches and knife edges from dulling or chipping. Weaver recommends it under a marble slab or a poly board.

Then the forum pushes back. In a thread titled poundo boards dull punches, the original poster passes on a supplier video’s claim that poundo dulls punches and hard plastic is better. TonySFLDLTHR says the rubber’s give makes punching less efficient because the board bounces, and that a poly board gives a solid surface. Tugadude points out that soft doesn’t automatically mean safe for tools. Nobody in the thread ran a test. It’s makers’ experience against makers’ experience.

The old answers are still around. In a thread on traditional cutting and punching mats, bruce johnson cuts on HDPE and punches on LDPE, which he says lets the punch edges sink in lightly for cleaner holes. MarshalWill punches on end-grain blocks, the saddle-shop way. SUP punches thick leather on a wax slab, because the wax lubricates the chisel tips each time they go through.

My opinion: the board under a chisel matters more than the board under a knife. A knife forgives a little. A row of chisel prongs hitting something too hard, again and again, does not.

When does stone earn a place on the bench?

For stamping, setting hardware and skiving. Never as a cutting board.

Granite and marble aren’t cutting surfaces. They’re anvils. Weaver’s granite tooling slab is sold for tooling, stamping, carving and setting hardware, and the listing tells you to put it beneath a poundo board or cutting board when you punch and cut. One reviewer on that page says it keeps his tools from denting his workbench, which tells you what the stone is protecting. The bench.

Skiving is the other job for a hard face. In the cutting surfaces thread, bikermutt07 skives on granite, quartz or glass, because the blade’s edge rides the hard surface and holds the angle, and he calls marble too soft. zuludog skives on an old glass oven door. In the layout thread, rbrooks recommends an old glass TV front. Thinning bridle without gouging it is its own fight, and the post on skiving and splitting gets into it.

My opinion: a slab under a rivet setter is the cheapest upgrade a beginner can make. A hammer blow into a wooden tabletop goes soft. Into stone, it goes where you aimed it.

How do you keep the surface from eating the work?

Treat the cover as a consumable and the leather as the thing you can’t replace.

Some shops don’t buy fancy surfaces at all. In the traditional mats thread, MarshalWill writes, “In the saddle shop we just cut on plywood screwed to the workbench.” In the cutting surfaces thread, fredk cuts on cheap hardboard and swaps it out when it wears. The layout thread has ChuckBurrows suggesting a rubber horse stall mat. Barn equipment and saddle-shop plywood, and none of it pretty.

My opinion: that’s the honest approach. Cheap, flat and replaced often beats expensive and scored to death, because a groove in the surface is a groove your next cut will want to fall into. Rotate a mat so you don’t cut the same line every time, which is the Creative Curator’s advice too.

Grain is the other worry. In the cutting surfaces thread, the original poster, Dun, lays scrap leather under a piece whenever the grain side faces down. A bend of bridle with a scratch pressed into its face from a gritty board is a panel I can’t use. I work from rulers and by eye, the way a sculptor might, rather than templates, so I’m looking hard at that face the whole time I’m laying out a briefcase. The post on cutting a briefcase out of a bridle bend is about where those panels come from. Wipe the board before the leather goes down. Every time.

Does any of it matter once the needle is in my hand?

For the stitch, less than you’d think. For everything before it, more.

Here’s where my own argument runs out. I just spent most of this post on surfaces, and the part of the job I care about most barely touches one. My Art of Hand Stitching page says I stitch “in the air,” meaning the sewing takes place in my hands instead of pushing a needle against a metal plate. The Maker page puts it shorter: “I sew in the air.” I stitch with my whole body, and helpers who sat and moved only their fingers got told to stand up and move with the piece. Not a bench in sight.

So the bench doesn’t make the stitch. My opinion: it makes the cut line the stitch follows and the holes the needle goes through, and if those are off, the hands can’t save it. A ragged punch on a bouncing table is a crooked row of holes, and a crooked row of holes is a crooked seam no matter how clean the thread runs on both sides.

That’s the trade. You can spend a lot on a slab and a board and a mat, or screw plywood to a table the way the saddle shops did. The leather won’t know what the surface cost.

It knows whether the surface moved.
