Our take on the Arenviy 4-in-1 Kitchen Knife Sharpener

The Arenviy 4-in-1 is a manual countertop knife sharpener with four slots: coarse 100-grit, medium 180-grit, fine 400-grit and a 1200-grit polishing stage. It measures 11.61 x 2.17 x 3.35 inches, so it stores in a drawer or sits on the counter without taking much room. Arenviy rates it for both home and commercial use. At $11.99 at Walmart as of November 4, 2026, it is a low-cost entry point; it is the only new price listed, so there is no recent range to compare against.

Questions and answers

Is the Arenviy 4-in-1 worth buying?
At $11.99 at Walmart as of November 4, 2026, it is a cheap way to keep everyday kitchen knives usable. It will not match a whetstone or a guided system for edge quality, but it costs far less.
Which slot should I use first?
Start with the 400-grit fine slot if the knife only needs a touch-up. Use the 100 or 180-grit slots only for a chipped or very dull blade, then finish with 400 and the 1200-grit polish.
Does it work on serrated or Japanese knives?
No. Pull-through slots like these are made for standard Western double-bevel knives. Serrated edges and hard, thin Japanese blades can be damaged by the coarse grits.
How often should I sharpen with it?
Use the fine and polishing slots every few weeks for regular kitchen knives, and save the coarse slots for when the knife actually fails to cut. Frequent coarse sharpening shortens blade life.
What is in the box?
The sharpener itself. It is a manual unit, so no power adapter or extra stones are needed.
When is it cheapest?
The listed new price is $11.99 at Walmart as of November 4, 2026, and only one store lists it new. Watch for holiday kitchen sales, when small gadgets like this often drop a few dollars.
