The Longzon 5-in-1 knifeener impressed me with its ability to revive even the dullest blades in just a few passes. The four stages—coarse, fine, and honing—work sequentially to grind, refine, and polish the edge, resulting in a noticeably sharper cut. I tested it on a neglected chef’s knife and a pair kitchen shears, and both came back to life without any damage. The included cut-resistant glove is a nice safety touch, especially for those new to sharpening.
However, the plastic body feels a bit lightweight and can wobble if not pressed firmly on countertop. It also takes some practice to maintain a consistent angle, as the slots guide the blade but don’t lock it in place. Despite these minor drawbacks the performance is reliable for the price, making it a great budget-friendly option for home cooks who want to keep their tools sharp without investing in expensive equipment.

My Honest Opinion

I tested it on a few dull kitchen knives, and after a few passes, they were noticeably sharper, easily slicing through tomatoes and paper. The included cut-resistant glove is a thoughtful addition, though it’s not as protective as a full cut-proof glove, so I still recommend careful handling.
One downside is the mess—metal dust accumulates quickly, so you’ll need to clean up after each use. The sharpener itself feels a bit plasticky, but it holds up well for occasional sharpening. Overall, it’s a practical, budget-friendly solution for keeping your knives in decent shape especially if’re not ready to invest in a more expensive system.
