Handheld Knife Sharpener, Long-Grip 3-Stage and 4-Stage with Non-Slip Base

It is $29.99 for the 3-Stage version and $34.99 for the 4-Stage version, and shipping is free. You receive one sharpener in the version you picked. The knives pictured with it are props and do not come in the box, so the price is for the sharpener alone.

Your non-dominant hand holds the long handle and presses the body onto the counter. Your dominant hand holds the knife and does all the pulling, heel to tip. The steadying hand should stay on the handle the whole time, never over the slots or in the path of the blade.

Yes. Hold the handle in your right hand and draw the knife with your left. Each slot grinds both sides of the edge in the same pull, so there is no need to flip the knife or switch hands partway through. The motion is simply mirrored.

Set it down. The non-slip base is made to grip a dry, flat counter while one hand holds the handle. Holding it in the air takes away that stability and puts the blade path close to your hand, so always rest it on a surface first.

It can be, if the board is dry and sits firmly without sliding. The base grips best on a dry counter. If your board rocks or skids when you push on it, move the sharpener to the bare counter, because a moving board carries the sharpener with it.

Lightly. The abrasive in each slot does the cutting, so pressure only makes it bite deeper and remove more steel than the edge needs. Heavy pressure also loads the base sideways and can make it creep. A light, even pull from heel to tip works better.

Straight-edge, double-bevel kitchen knives such as chef, paring, utility and santoku blades. It does not suit serrated bread or steak knives, single-bevel Japanese knives like a yanagiba, deba or usuba, or scissors, because each slot is shaped to grind two matching faces on a straight edge.

Two or three in coarse, and only if the edge is chipped or dead. Several in medium for everyday sharpening. Then three to five light pulls in fine to polish the edge and remove the burr. On the 4-Stage, give the second finishing slot a few light pulls as well.

The 3-Stage at $29.99 covers repair, sharpening and polishing. The 4-Stage at $34.99 adds a second finishing slot for one more refining pass. Both use the same grip and base. If you want the simplest option, choose the 3-Stage; if you want an extra finishing step, choose the 4-Stage.

Tap the sharpener over the trash to shake out metal filings, then wipe the body and base dry with a cloth. Do not put it in the sink or the dishwasher. A clean, dry base also grips the counter better next time, since dust and oil reduce its hold.

Usually the counter is wet or greasy, or you are pressing too hard. Wipe the surface dry, press the handle straight down with your steadying hand, and use a lighter pull. If it is sitting on a cutting board, the board itself may be sliding, so try the counter.

On the long handle only, wrapped around it and pressing the body down. Keep it behind the slots and out of the line the knife travels. With the slots pointing away from you and the knife coming toward you, your steadying hand stays clear of the edge.

Stand square to the counter with the sharpener directly in front of you and the slots running away from your body. That lets you pull the knife toward yourself in a straight line with your arm, rather than twisting your wrist, which keeps pressure even from heel to tip.

Keep the whole base on the counter so it can grip. If part of it hangs over the edge, the base loses contact and the sharpener can tip while you pull. Set it fully on the dry surface, a little in from the edge, with room for the knife to travel.

The long handle is meant for a full-hand grip, and the steadying hand only has to hold it down, not squeeze hard, because the non-slip base shares the load. Exact handle dimensions are not published, so we cannot give a measurement to compare against your hand.

It fits a busy kitchen because there is no setup: set it on a dry counter, hold the handle, and pull. The fixed preset angle means you do not stop to judge anything. It is limited to straight, double-bevel knives, so it will not cover serrated or single-bevel blades.

No. It is powered by your pull alone and works dry. There is no water to soak, no oil to spread and no outlet to find, which is part of why it can live in a drawer and come out right where you are cooking.

Wipe the edge on a folded cloth, then slice a sheet of copy paper held by one corner. If it glides through cleanly, you are done. If it snags or tears, give it a few more pulls in medium, then finish again in fine before testing once more.

The sharpening inserts sit in a stainless steel housing, and the body and handle are plastic. It comes in black or red. The exact abrasive material, size and weight are not published, so we describe only what is confirmed about the build.

No. Care does not change the shape of the slot. Each slot grinds a flat face on both sides of a straight edge, and the teeth of a serrated knife sit where the abrasive cannot reach them properly. Do not put serrated knives in it.

Keep the blade upright and pull slowly and lightly, and a slip is unlikely. If the knife twists sharply in the slot, the edge can catch. That is another reason to keep pressure light and the base on a dry surface. The coarse slot can repair a chipped edge if it happens.

In a utensil drawer. It is compact enough to sit beside your other tools, though exact dimensions are not published. Tap the filings out and wipe it dry before storing so loose metal stays out of the drawer.

Yes. A knife that is only dull needs several light pulls in medium and three to five in fine, then a wipe on a cloth. Because nothing needs soaking or setting up, you can do it between tasks and go straight back to chopping.
