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

The Arenviy 4-in-1 is a manual countertop sharpener with four stages: coarse 100 and 180 grit for reshaping, 400 grit for honing, and 1200 grit for polishing. It measures 11.61 x 2.17 x 3.35 inches and is rated for home or commercial use. At $11.99 at Walmart as of November 4, 2026, it is the only new price listed, so there is no recent range to compare against. It suits buyers who want a cheap, no-setup way to bring dull kitchen knives back to a usable edge.

Questions and answers

Is the Arenviy 4-in-1 worth it?
At $11.99 it is a cheap way to keep inexpensive kitchen knives usable. If you own good knives, a guided rod or stone system protects the edge better.
Which stage should I use?
Start with 100 or 180 grit only if the edge is damaged or very dull. Use 400 grit for routine honing and 1200 grit for a final polish.
Does it work on serrated or ceramic knives?
No. Pull-through slots like these are made for plain steel edges. Serrated edges and ceramic blades need different tools.
How often should I sharpen?
For home cooking, a few passes on the 400 grit stage every few weeks is usually enough. Save the coarse stages for knives that have lost their edge badly.
When is it cheapest?
The only new price listed is $11.99 at Walmart as of November 4, 2026. With one seller, there is little to compare, so watch for seasonal kitchen sales.
Where is the Arenviy 4-in-1 Knife Sharpener cheapest?
