Lay the strop flat, set the blade on it at the angle you sharpened at, and pull it backward, spine first, so the edge trails behind. Use about the weight of the knife and no more. Do ten to twenty strokes a side after sharpening, alternating sides, or five to ten for a quick daily touch-up. Stropping polishes the edge and strips the last of the burr that sharpening leaves behind, which is why a knife often feels sharper after the strop than it did off the stone.
What stropping does
Every sharpening stone leaves a burr: a thin wire of steel folded over the edge. If you leave it there, the knife feels sharp for a few cuts, then the burr folds and the edge goes dead. Stropping drags the edge backward through leather, which flexes the burr until it breaks off and polishes the scratches left by the stone. With compound on the leather, it also removes a tiny amount of steel, about the way a very fine stone would. That works for a small burr. A big one from a coarse stone should be shrunk on finer grits first, as our knife sharpening burr guide explains.
It isn't sharpening. A strop can't fix a rounded or chipped edge; Knafs puts it plainly that stropping does not replace sharpening. And it's different from a honing rod, which pushes a rolled edge upright. Many cooks use both: rod for the daily wobble, strop after sharpening.
The stroke: edge trailing
- Set the strop on a flat, stable surface. A strop glued to a board (a paddle or bench strop) is easier than a hanging strap because it can't sag and round the edge. Straight razors are the exception: they go on a taut hanging strop, as our straight razor strop guide explains.
- If you're using compound, rub it onto the leather like a crayon, a thin even coat, then spread it with your thumb.
- Start with the heel of the blade near the far end of the strop and the edge facing away from you. Lay the blade flat, then lift the spine until the edge touches. That's roughly your sharpening angle.
- Pull the knife toward you, spine leading, sweeping from heel to tip as you go so the whole edge crosses the leather. On a curved belly, Knivesandtools says to follow it by turning your wrist rather than your whole arm.
- At the end of the stroke, lift the knife straight up. Don't roll it over the edge.
- Flip the knife and do the same on the other side, moving away from you, still spine first. Alternate sides each stroke.
The most common mistake is the end of the stroke. People finish by tipping the spine up, which drags the very edge across the leather at a steep angle and slowly rounds it. Lift the whole knife off instead.
Angle and pressure
Strop at the angle you sharpened at, or a degree or two higher. Leather gives under the blade, so it forgives small wobbles better than a stone, a point Work Sharp makes too. Two cues from Knivesandtools tell you when you're off: if you see the side of the blade shining where it rubs, raise the spine; if you hear the leather scrape, lower it. Coloring the bevel with a marker shows it even more clearly, the same way the sharpie trick works on a stone.
Pressure should be light, and lighter toward the end. Work Sharp's advice is to ease off as you go, since lighter pressure leaves a finer edge. Heavy pressure presses the edge into the leather and rounds it.
How many strokes, and when
| Situation | Strokes per side | Surface |
|---|---|---|
| Right after sharpening on stones | 10–20, alternating | Compound side, then a few on bare leather |
| Daily or weekly touch-up | 5–10 | Compound side |
| Mid-task (hunting, carving) | 3–5 | Whatever's at hand: pocket strop, belt |
| Still dull after 20 strokes | stop | Go back to a whetstone |
Test with a sheet of paper after each set. A clean, quiet slice from heel to tip means you're done. Work Sharp's extra test is a push cut: a very sharp edge goes straight down through paper with barely any slicing motion.
Compound colors, decoded
"Green compound" sounds like a standard. It isn't. Here's what the listings and makers we checked say their compounds are:
| Compound | What the maker states |
|---|---|
| SHARPAL 208H green | Aluminum oxide and chromium oxide, 1 to 2 micron particles |
| Work Sharp green (in its strop article) | About 0.5 to 1 micron |
| Bacher strop kit, four pastes | Red 2000, white 5000, green 8000, black 12000 (grit labels, with lanolin and beeswax) |
| Knivesandtools' general advice | One compound only: pick a medium 5 to 2 micron |
So a green from one brand can be twice as fine as a green from another. For a kitchen knife, one fine green compound on one side of the strop and bare leather on the other covers nearly everything. If you sharpen to a high-grit stone and want to step down, a multi-paste kit like the Bacher lets you go coarse to fine.
Which strop to use
- A bench strop with two sides gives you compound on one and bare leather on the other. The SHARPAL 204N is 8 by 3 inches of cowhide on a wood base with non-slip feet and a green compound, per its listing.
- The SHARPAL 205H is a 13.2-inch paddle with a smooth side and a suede side, a 2-ounce compound bar and an angle guide, a good fit for long kitchen knives.
- The Hutsuls 3 x 8 inch strop is 4 mm buffalo leather with a smooth and a rough side.
- For carving tools and chisels, the BeaverCraft 14-inch paddle.
Thicker leather on a rigid base is better than thin soft leather: Bacher's listing explains that thin hide sinks under the blade and rounds the apex. Our best leather strop guide compares six of them.
No strop? What works instead
A smooth leather belt pulled tight over a table edge, the back of a leather notebook, a pair of jeans laid flat, or the plain side of a cardboard box all do the job with the same edge-trailing stroke. Work Sharp names denim, canvas, a coarse leather belt and cardboard. Newspaper on a flat table works for a final few passes. Rub a little compound on any of them if you have it. The trick is a firm, flat backing; anything that sags will round the edge. More household methods are in how to sharpen a knife without a sharpener.
Serrated knives and other blades
Don't drag a serrated edge across a strop. The points dig into the leather and cut it, and Knafs and Knivesandtools both warn against it. You can strop the flat back side of a single-sided serrated blade lightly to remove a burr. Chisels and plane irons strop the same way; see how to sharpen a chisel. Hobby blades strop well too, as covered in how to sharpen an X-Acto knife. Axes get a strop on leather glued to a board, which the US Forest Service ax manual calls the best way to take off the last wire edge.
Looking after the strop
The leather turns black with steel and compound. That's normal. When it starts to look shiny and glazed, Knivesandtools suggests roughing it lightly with a wire brush to open the surface. If the leather dries out and the compound won't stick, Work Sharp's fix is a little petroleum jelly rubbed in, then fresh compound. SCOTTCHEN's listing suggests a little mineral oil on dry, hard leather, or warming a stiff compound bar with a hair dryer before applying it. Keep the strop covered so grit from the bench doesn't get on it; one stray grain will scratch every edge you polish.
