If your straight razor is pulling at the hair instead of slicing through it, work out which of two jobs you actually have before you buy anything. Stropping and honing both get called “sharpening”, they use different equipment, and doing the wrong one costs you an evening and possibly an edge.
Stropping realigns an edge that is still sharp. Honing removes steel to create a new edge. Most razors that feel dull need the first, or a short touch-up on a very fine stone — not a full session on a coarse one. A complete honing, starting from a bevel set, is an occasional job measured in months, not a weekly chore.
Who this is for: someone whose razor has started to tug, who wants to know whether they can fix it themselves, and what they need if they can. Who should skip it: anyone whose blade has a chip, a crack, or rust along the edge, and anyone who bought a cheap razor that was never ground to shave. A stone will not fix either of those, and working on them can make things worse.
The two jobs, and why the words matter
A leather strop does not sharpen in the sense most people mean. It removes no steel. What it does is straighten the microscopic teeth along the edge that bend out of line during a shave. Boker, who have made straight razors since 1869, describe the burr as “like a comb whose teeth are bent in all directions after shaving”, and say the strop “realigns these teeth into an even burr”. Their own wording is that untreated leather “does not remove material from the edge, i.e., it does not sharpen the razor in the usual sense.”
Honing is the job that removes metal. Cut Throat Club describe it as “restoring the blade’s sharpness when it’s past the point of mere stropping”, using “a series of abrasives until it’s back to being shave ready.” That is why the two use different equipment and why the order matters: you hone when stropping has stopped being enough, then you strop the result.
There is a step between the two that is easy to forget. A strop charged with a mild abrasive paste does remove a small amount of steel, and it sits between plain stropping and honing. Boker recommend a second strop treated with red grinding paste once cutting performance drops despite regular stropping, noting that “this process actually does remove a minimal amount of steel”. If a pasted strop does not bring the edge back, that is the signal to get a stone out.
Before you touch a stone: three checks
Honing a razor that did not need it removes steel you cannot put back. Two minutes of checking prevents that.
1. Does it shave arm hair?
ShaveSmith, who hone razors commercially, use the arm-hair test as the working standard: a sharp edge should “catch and cut with a bit of a tug” when drawn slowly over the tops of the hair on your forearm. If it does that, your edge is still there and you are looking at a stropping problem, not a honing problem.
2. What does the edge look like?
A jeweler’s loupe is the cheapest useful tool in straight-razor maintenance. Under magnification you can see whether the edge is merely misaligned or actually rounded, and whether there is a chip. Watching how the scratch pattern on the bevel changes as you work is also the fastest way to learn what your strokes are doing.
3. Is the edge damaged?
Chips, cracks and rust on the cutting edge change the job completely. ShaveSmith are blunt about the risk: “Honing a razor for shaving with a crack can be dangerous, and removing chips is often a bigger task than you imagine.” Surface rust on the spine or tang is cosmetic; rust or a chip on the edge is not.
Which stone you need
If you are touching up an edge that was honed properly in the first place, you want one very fine stone. ShaveSmith’s routine for that case is short: “a few x strokes (35 or so) on a 12k or higher stone”, followed by stropping on plain leather. That is the whole job. You are polishing an edge that already exists, not creating one.
A 12,000-grit finishing stone is the tool for that, and a Naniwa at that grit is what ShaveSmith list in their own kit for the final polish. The NK-2091 is a 210 × 70 × 10 mm stone that ships in a storage case, which matters more than it sounds: the finishing stone is the one you want to keep protected between sessions.
If the edge has gone further than a touch-up — or the razor arrived without a usable bevel — you need a progression, and the first stone in it does most of the work. Cut Throat Club put roughly 75% of honing time on the 1000-grit stone, 15% on 4000 and 10% on 8000, which is worth knowing before you buy: the coarse stone is not the optional one, the fine ones are.
A combination stone covers the start and middle of that progression in one purchase. The King KW65 gives you 1000 grit on one face and 6000 on the other. King stones are soft and cut fast, which is what you want when you are removing material, with the trade-off that they go out of flat sooner, so they need truing — that is, flattening back to true — more often. The other side of that trade-off is worth knowing before you pick: harder stones, oilstones among them, stay flat longer and need truing far less often, but they cut more slowly than a soft water stone.
Two stones is a reasonable place to stop for most people: a 1000/6000 combination for the work, and a 12000 for finishing and future touch-ups. What you do not need is a wide set of intermediate grits. ShaveSmith’s advice is to get the edge as sharp as it will go on one stone before moving up, because “if it’s painful to shave after your lowest stone… you’re not done, and moving up the stones will not benefit your edge.”
The stroke: let the spine set the angle
This is the part that decides whether honing works, and the part most easily got wrong if you have sharpened knives before. You do not hold a straight razor at an angle. You lay it down so that both the spine and the cutting edge are touching the stone, and the thickness of the spine holds the edge at the correct angle for you.
Cut Throat Club state it directly: “Both the edge and the spine of the razor should be in contact with the stone. This positioning ensures that the spine sets the angle for honing.” ShaveSmith describe it as keeping “the razor spine and edge completely flat on the surface together”.
That means any instruction to tilt the blade to a specific angle — 20 degrees, 30 degrees — belongs to knives, not razors. Lift the spine and you lift the edge off the stone, and you are no longer honing the razor; you are rounding it. If you take one thing from this page, take that.
The sequence
- Set the bevel on the coarse stone. ShaveSmith use small circular strokes — roughly 30 to 40, worked down the stone — then repeat on the other side. This is the one stage where a little pressure is acceptable, because you are removing material on purpose.
- Refine on the finer stones. Once the edge will catch arm hair along its whole length, switch to straight strokes down the stone and stop using pressure. Cut Throat Club’s instruction is to move the razor away from you with no additional pressure, then draw it back.
- Flip over the spine, always. At the end of every stroke, turn the razor on its spine. Boker are emphatic: “Under no circumstance should you flip the straight razor over the edge – this would round off the edge again, i.e. blunt it.” This single habit is the difference between maintaining an edge and rounding it.
- Cover the whole edge. Work heel to toe. If your stone is narrower than the blade, angle the stroke slightly so the contact point travels along the edge, and check the whole length with the arm-hair test rather than just the middle.
If you want to protect the spine from wear, a strip of electrical tape folded over it is the standard trick. It also shifts the angle a hair, so pick one approach and stay with it.
The liquid mistake that changes the stone
A stone needs a liquid, and the liquid has a job beyond lubrication. Dictum explain the actual purpose: the fluid “prevent[s] the abrasion from the tool and stone from settling on the stone surface”, which would otherwise clog the abrasive and stop it cutting.
The liquid is decided by the stone, not by preference, and you do not switch. Some stones clog with water and must be used with oil; Arkansas stones are the standard example. Japanese water stones are the opposite: they are used with water. On a stone that tolerates either, Dictum’s guidance is still to “stick with the chosen liquid once you have decided”.
Which is why the common instruction to soak a water stone and then apply honing oil to it is not a shortcut, it is a contradiction. Soaking is what you do to a water stone. Honing oil is what you use on an oil stone. Doing both to the same stone leaves you with a stone that is wet and oiled, so you have changed the stone rather than prepared it. The guidance is simply to stick with the liquid you chose.
So: water stone, water. Keep it wet through the session — Cut Throat Club’s rule is plain, “Don’t hone on a dry stone” — and re-wet as the surface dries. Oil stone, oil. If you own one stone of each, keep them separate and keep the liquids with them.
One more reason this matters on a razor specifically: most straight razors are carbon steel, and water promotes corrosion in carbon steel quickly. Dictum note that the water “must be removed without leaving any residue after sharpening”. Dry the blade properly the moment you finish, and oil it.
Keep the stone flat
A dished stone cannot produce a straight edge, and every stone dishes eventually, soft water stones faster than most. Cut Throat Club’s precondition is that “your stones are perfectly flat or lapped; if they’re uneven, it could lead to blade damage.” ShaveSmith go further, flattening before each use and noting that stones do not arrive flat from the factory.
A diamond flattening plate is the durable answer; wet-and-dry paper on a flat tile or a sheet of glass is the cheap one. Flattening also clears the spent abrasive off the surface, which restores the stone’s cutting speed.
Stropping, properly
Stropping is the routine that keeps you off the stones, so it is worth doing correctly. The mechanics are close to honing: spine and edge both on the leather, spine leading, no downward pressure, and flip over the spine at the end of each stroke rather than over the edge. Boker make the same point about the strop specifically: the geometry of the razor gives you the right angle on the edge when the spine touches the leather. If you want the full walk-through of the equipment and the motion, we cover it in what a barber leather razor strop is and how to use one.
If your strop has a linen or canvas side, use it first. Boker explain why: the linen’s weave “catches dirt and loose steel particles which could damage the sensitive edge” before the leather does the aligning. A dual-sided strop gives you both faces on one strop.
Two habits matter more than stroke count. The first is timing: strop before you shave, not after. Boker’s reasoning is that steel has a kind of memory, and ripping a freshly stressed burr back into line shortens the edge’s life. They recommend letting the razor rest at least 24 hours, ideally 48, which is why straight-razor shavers tend to own more than one razor. Cut Throat Club give the practical version: stropping after a shave can embed the leather with metal fragments from the blade.
The second is that counts differ by job, so do not treat any number as law. Cut Throat Club suggest 20 to 40 round trips for routine stropping; ShaveSmith do 150 to 200 passes on leather after a honing session. The difference is real and comes from what each is trying to achieve, not from one of them being wrong. Start at the lower end, and add passes if the shave still tugs.
When plain stropping stops holding the edge for a full shave, that is when you move to a pasted strop or a finishing stone, in that order. If you would rather compare strops before committing, our guide to straight razor strops covers what separates a strop that stays flat and taut from one that cups.
When honing will not fix it
Some razors cannot be made to shave well, and it is worth saying so plainly because the alternative is an hour on a stone and the same bad shave at the end of it. ShaveSmith name the causes as poor steel, blades that were not hand ground, which leaves the hollows and edges uneven, and poor overall geometry. They add that razors bought cheaply online regularly arrive in a state that cannot be corrected at all.
If your blade has a crack, a chip you cannot see the bottom of, or heavy rust along the edge, the honest options are a professional honing service or a different razor. For the second, our guide to choosing a straight razor covers what to look for in the steel and the grind, which is a better use of your money than a stone you cannot use.
Where to start
If the razor still catches arm hair, strop it properly before your next shave and see whether that was the whole problem. If the edge is there but the shave still tugs after a good stropping, buy a 12,000-grit finishing stone and do 35 light strokes before stropping. If the edge has gone, or the razor never had a proper bevel, start on a 1000-grit stone, verify the edge on your arm at every stage, and do not move up until it cuts.
Three tools cover everything on this page: a coarse-to-medium combination stone, a finishing stone, and a strop with a linen side. Everything else — the pastes, the flattening plate, the loupe — is an upgrade you can add once you know you will keep using them.
