How to Sharpen Kitchen Knives: A Whole-Block Routine With a Pull-Through Sharpener

Use a tool with a preset angle so there is nothing to judge. With this pull-through, draw each straight double-bevel knife heel to tip through medium several times with light pressure, then three to five light pulls in fine, then wipe the edge. Coarse is only for chipped or dead edges.

It depends on use. A chef knife or santoku used every night usually needs a medium-and-fine touch-up every couple of weeks. A paring knife can go a month or more, and a carving knife used for holidays only needs it before the meal. The paper test tells you for sure.

A routine anyone can repeat. This sharpener has a preset angle in each slot, so whoever does it gets the same result. Sort the block, check each straight knife with copy paper once a month, and only sharpen the ones that snag.

The 3-Stage is $29.99 and the 4-Stage is $34.99. Shipping is free on both. There is nothing else to buy later, since it needs no power, water, oil or replacement stones to run.

Straight-edge, double-bevel knives: chef, santoku, utility, paring, and similar straight kitchen blades ground on both sides. Knives with a toothed edge, single-bevel Japanese knives and scissors are not a fit and should be set aside before you start.

Only a few minutes for a typical block of straight knives, because each one needs roughly a minute: several pulls in medium, three to five in fine and a wipe. Knives that pass the paper test can be skipped, which shortens the session further.

The 3-Stage covers everything a monthly routine needs: repair, sharpening and polish. Pick the 4-Stage if you sharpen often and want a second finishing pass for a smoother edge. Both handle the same knives.

Not with light pressure and the right slots. Medium and fine remove very little steel, and knives that still pass the paper test can skip a month. Wear speeds up when people press hard or use coarse every time, so keep coarse for real damage.

Tap the filings out over a bin and wipe the body dry. Keep it out of the sink and out of the dishwasher. Then it goes back in the utensil drawer until the next session.

No. It is not for serrated knives, so the bread knife stays out of the routine. Toothed edges hold up for a long time anyway, and they need a tapered tool made for their shape when they do finally dull.

Slice a sheet of copy paper held by one corner. If the knife glides through, skip it. If it catches, folds or tears the paper, give it several pulls in medium and three to five in fine, then test again.

Yes. Knives loose in a drawer knock against each other and dull faster. A block, a magnetic strip or blade guards keep the edge off other metal. Cutting on wood or plastic rather than glass or stone also keeps edges sharp longer.

Sharpen by how the knife performs, not by a fixed date. Run the paper test on every straight knife each month. The ones used most will fail more often and get medium and fine; the rarely used ones will pass and get skipped.

No. Coarse is a repair stage for a chipped or completely dead edge, and it should get only two or three pulls. In a regular household routine, start in medium and finish in fine. Starting in coarse every time removes steel the knife did not need to lose.

Anyone old enough to handle a kitchen knife can follow the same steps: hold the long handle with one hand, pull the knife toward you heel to tip with the other, and keep fingers behind the handle. Adults should supervise younger teens, as with any knife task.

Yes, if it is double-bevel, meaning ground on both sides, which most home santoku knives are. Single-bevel Japanese knives such as a yanagiba, deba or usuba are not a fit, so check the edge from both sides before you begin.

Set them aside when you sort the block. Toothed edges need a tapered tool, and single-bevel knives need a stone rather than this sharpener. Most home blocks are mainly straight double-bevel knives, so this tool usually covers the ones used every day.

A day or two before, run the carving knife and chef knife through the paper test. If either snags, give it several pulls in medium, three to five in fine, and a wipe. Test again on paper so you know the edge is ready for carving.

No. There is no cord, no batteries, no water and no oil. It works on a dry counter with a non-slip base, which keeps a monthly session quick to set up and quick to put away.

In a utensil drawer. It is compact enough to sit with spatulas and tongs, so it stays in reach without taking counter space. Exact dimensions and weight are not published.

Skip the knives that pass the paper test and do only the ones that snag. For each, use several light pulls in medium and three to five in fine, then wipe. The preset angle means there is nothing to set up or adjust.

One sharpener in the version you chose, 3-Stage or 4-Stage. Knives, boards and props in the photos are not included. It needs no accessories to work, so there are no stones, oils or cords to unpack, and it is ready for the first session straight away.

Black and red. The inserts sit in a stainless steel housing and the body and handle are plastic. Both colors sharpen the same way, so pick whichever suits your kitchen drawer or counter.
