To use a Lansky sharpener, clamp the knife by the spine with about half an inch of blade showing, screw a guide rod into a hone, and drop the rod into the 17, 20, 25 or 30 degree hole that matches your knife. Stroke edge-first toward the clamp, a short section at a time, until you feel a burr. Flip the clamp, match the stroke count, then repeat on each finer hone. That's the whole system. The details below are what separate a crisp edge from a rounded one, and they come from Lansky's own instructions on lansky.com. If you're still choosing between guided tools, start with our best sharpening system guide.
What's in the box, and what each part does
Every Lansky controlled-angle kit has the same four parts, whichever kit you bought:
- The clamp. An aluminum jaw with two thumbscrews and the four angle holes on one end. It flips over so you can sharpen both sides without unclamping.
- Hones on finger-grooved plastic holders, color-coded by grit.
- One guide rod per hone. The rod threads into the end of the holder and rides in the angle hole.
- Oil or a brush. Alumina oxide kits come with Nathan's honing oil; diamond kits come with a nylon brush instead.
The Lansky Deluxe 5-stone is the kit most owners have (more than 14,000 Amazon ratings when we checked). Its hones, per lansky.com, are a 70 extra coarse, 120 coarse, 280 medium and 600 fine in alumina oxide, plus a 1000 ultra fine ceramic. Our Lansky kit comparison covers what the other kits change. Everything on this page works the same on all of them.
Step 1: clamp the knife so the angle is true
This is the step that decides the angle, so it's worth doing slowly. Lansky's clamp instructions, in order:
- Loosen the front screw.
- Tighten the back red thumbscrew until it's about one full turn from fully tight.
- Loosen the front screw again to fit the blade's thickness.
- Put the clamp on the spine at the center of the blade, with about 1/2 inch of blade sticking out of the jaws.
- Tighten the front screw, then lock everything by hand-tightening the back thumbscrew.
That half inch matters more than any other number in the kit. The guide rod pivots in the hole, so the angle depends on how far the edge sits from that hole. Clamp a wide blade with an inch showing and the edge sits farther away, so the real angle comes out lower than the number stamped on the clamp. Clamp a narrow blade deep and it comes out higher. The stamped numbers are only exact at Lansky's half inch.
Two clamp limits from lansky.com: the standard clamp holds blades up to about 7 inches long and narrow blades down to small Swiss Army-type blades 1/2 inch wide or less. For polished or coated blades that scratch easily, Lansky suggests its Soft-Grip rubber-jaw clamp, which isn't meant for blades 1/2 inch wide or narrower.
Step 2: pick the hole
Lansky's own labels describe 17° as a "severe" angle for razor blades and scalpels, 20° for "higher quality blades" including kitchen cutlery and fillet knives, 25° for most knives that need a durable edge (hunting and outdoor knives), and 30° for knives that cut cardboard, wire or carpet. Those are per-side figures.
The better rule is to match what's already on the knife. Color the bevel with a marker, make three or four light strokes with the fine hone in the hole you think is right, and look:
| Marker comes off | What it means | Do this |
|---|---|---|
| Across the whole bevel | The hole matches the factory angle | Sharpen here |
| Only at the very edge | Hole is steeper than the bevel | Drop one hole, or accept a slightly steeper microbevel |
| Only at the shoulder (top of the bevel) | Hole is shallower than the bevel | Go up one hole, or expect a long regrind on the coarse hone |
| Heavier at the tip than the heel | Blade width changes along its length | Sharpen in zones (step 5) and recheck each one |
Our Sharpie trick guide has photos of what each pattern looks like, the knife sharpening angle chart lists factory angles by knife type, and the angle calculator shows where your brand's number falls between Lansky's holes. If you're between holes, pick the higher one. A slightly steeper edge cuts nearly as well and you'll remove less steel getting there.
Step 3: set up the hones
Thread a guide rod into each hone you'll use. Lansky's hone instructions say to check that the rod lines up with the sharpening surface, and to bend it slightly if it doesn't. A rod that's bent away from the stone face tilts the hone and puts the scratch pattern off the bevel. Set the hones out coarse to fine so you don't grab the wrong one with oily fingers.
Holding the clamp in one hand is fine for a pocket knife. For anything longer, or if your clamp hand gets tired, a mount helps: the Lansky Super C-Clamp clamps to a table edge and the clamp screws onto its spindle, and the Universal Mount bolts to a bench through its pre-drilled base. Both free up a hand to steady the knife.
Step 4: oil, water or nothing
This is where most guides get Lansky wrong. Lansky's kit instructions give a different rule for each hone material:
| Hone | During sharpening | Cleaning |
|---|---|---|
| Alumina oxide (Standard, Deluxe, Professional) | No oil required | When the hone starts to feel smoother, it's clogging. A few drops of oil lift the filings; wipe them off. |
| Natural Arkansas | A few drops before you start; keep it oiled | Wipe off the gray slurry with the oil |
| Diamond | Never oil (Lansky says it can clog the diamond) | Water, the nylon brush, a little dish soap; dry fully before next use |
| Ceramic ultra fine | Lansky's kit sheet doesn't give a separate rule | Most owners use it dry and scrub it clean |
If your kit came with oil, it's mainly a cleaning fluid for the alumina oxide hones. Nathan's Natural Honing Oil is what Lansky packs, and our sharpening stone oil guide covers substitutes.
Step 5: the strokes
- Drop the guide rod of the coarsest hone you need into the hole. Use the 70 or 120 for a chipped or very dull edge, or when you're changing the angle. Start on the 280 if the knife only needs a touch-up.
- Stroke diagonally forward, toward the clamp, so the hone moves edge-first into the blade and travels along a short section of it. Lansky's instructions put it bluntly: always sharpen into the blade, never along it or away from it.
- Use the full length of the hone on each stroke, with generous pressure on the coarse hone.
- Count your strokes. Keep going until you can feel a small burr along the whole edge on the other side when you drag a fingertip off the edge (not along it).
- Flip the clamp over and do the other side with the same count.
- Move to the next hone and repeat with less pressure each time. On the fine and ultra fine hones, lighter alternating strokes shrink the burr.
For blades over 7 inches, Lansky's method is zones. Clamp two finger widths from one end, lay your two fingers beside the clamp, and only sharpen the strip of edge they cover, on both sides. Then measure two more finger widths from where you stopped, move the clamp there, and repeat with about the same number of strokes. Lansky says sharpening outside the zone changes the hone angle, which is why long blades sharpened in one clamping come out uneven. Our guide to the sharpening burr covers how to raise one and get rid of it.
Step 6: finish and strop
When the edge is as sharp as you want on the finest hone, you're done. If it isn't, Lansky's advice is to keep going on the fine hone rather than starting over. On single-bevel or serrated blades, lay the fine hone flat on the unsharpened side and drag it down the length a few times to knock off the burr.
The Lansky leather stropping hone fits on a guide rod like any other hone. Use the same hole you sharpened in, and reverse the motion: Lansky says to pull the strop away from the edge, not push into it. Jeweler's rouge on the leather is fine; Lansky says abrasive pastes wear it out. Our stropping guide covers compounds.
When it isn't working
| Problem | Likely cause | Fix |
|---|---|---|
| No burr after 50+ strokes | Hole is steeper or shallower than the bevel, or the hone is clogged | Recheck with a marker; clean the hone; drop to a coarser hone |
| Bevel wider at the tip than the heel | Blade narrows toward the tip, so the edge moves relative to the hole | Sharpen in zones and recheck each with a marker |
| Scratches on the blade face | Metal jaws, or grit trapped in the clamp | Tape the blade face or use the Soft-Grip clamp; wipe the jaws |
| Rod bottoms out or hits the clamp | Too little blade showing, or a bent rod | Reclamp with about 1/2 inch showing; straighten the rod |
| Tip rounds off | Hone slides past the tip | Shorter strokes near the tip; stop the hone before it falls off |
| Sharp on one side, dull on the other | Uneven stroke count after flipping | Count strokes per side, and per zone |
If the rod has a little play in the hole, keep it pressed against the same side of the hole on every stroke. That takes the slop out of the angle.
Using the Puck and the crock sticks
The Lansky Puck isn't part of the clamp kit, but it's Lansky's best-selling sharpener (more than 18,000 Amazon ratings when we checked), and "how to use a Lansky puck" is a common search. It's a dual-grit silicon carbide disc, 120 coarse and 280 medium per lansky.com, made for axes and mower blades rather than fine knives. Lansky's steps:
- Hold the tool firmly or lock it in a vise. Add a few drops of honing oil to the side you'll use, if you like (it's optional).
- Grip the Puck with thumb and fingers, backed by your palm, and move it in overlapping circles along the whole edge at a steady angle.
- Finish one side of the edge before doing the other.
Start on the coarse side for nicks and very dull edges, and use only the medium side for touch-ups. When dark gray patches build up and the Puck feels smoother, spread a few drops of oil on them, wait about a minute, and wipe them off with a lint-free cloth.
Lansky's TurnBox Crock Sticks are a different tool again: ceramic rods set in a wooden base at 20° or 25°. Lansky's method is to hold the blade straight up and down, start with the heel an inch or more below the top of a rod, and draw the knife down and toward you to the tip, like slicing bread, alternating rods. For a two-stage edge it suggests 10 to 12 strokes per rod at 20°, then finishing at 25°. Lansky's tip: don't let the knife tip roll off the rod.
Keeping it sharp afterward
Once the bevel is set at a Lansky angle, a touch-up is quick: clamp at the same spot, start on the fine hone, and do 10 or so strokes a side. Mark where you clamp each knife (a dot of nail polish on the spine works) so the angle comes back the same. If you find yourself wishing for an angle between the holes, or for no oil at all, read our Work Sharp vs Lansky comparison before buying another system. And if your knives are hard super steels, the Lansky 4-stone diamond kit uses the same clamp and holes with diamond hones (100, 200, 400 and 600 per its listing), so the method above carries over unchanged.
