Brilliant
So good and easy to use. I like the fact that it has a slot of scissors too as mine are blunt now but was able to sharpen them. I like the design too, the handle helps a lot and it has grips at the bottom for a sturdy hold whilst sharpening. Worth the price.

Great knife sharpener
I hate when I’m trying to chop my veggies and my knife just won’t cut properly. I’ve struggled to find a good knife sharpener, but I’m so glad I came across this one! It’s super easy to use and quickly brings my knives back to life. I love it!

Well built and solid, sadly no an expensive paper weight.
I was a bit gutted with this to be honest and I wouldn't normally bother with a negative review but I can imagine people buying this for the same reason I did. It looked handy and saves the mess using a stone or a steel to sharpen, but it went blunt really quickly. Not sure if you can buy replacement sharpening blades for it? It feels really well made and solid, sadly it became a bit useless after a few uses. It was a little disappointing, I should have stuck to the traditional method with a wet-stone I just thought this would be cleaner and save time.

I recently purchased this knife sharpener. I had scissors, long knives and short knives that needed to be sharpened. The price was phenomenal so I had to buy this item. I did some price comparison and Amazon had the best price. I have sharpened my scissors and all knives . It was easy and quick. The sharpener worked better than I initially thought it would. The clean up was easy and the gloves are a plus. I definitely would say this knife sharpener is a excellent choice!

Messerschärfer , Marke Longzon , geliefert im Jan 2025 : Bei technischen Artikeln , die aus China kommen , hatte ich sonst immer ein ungutes Gefühl. Zu oft hatte ich nach der Lieferung ein billiges Plastikteil in der Hand. Nicht in diesem Fall. Der gelieferte Messerschärfer macht einen durchaus wertigen Eindruck , und er macht was er soll : er hat einen gut dimensionierten Griff , ist rutschfest , gut gekennzeichnet und er schärft Messer und Scheren. Die Gebrauchsanleitung ist verständlich und gut. Dieses klein gedruckte Blatt "Handbuch" zu nennen finde ich zwar etwas übertrieben , aber die deutsche Beschreibung ist fast fehlerfrei , wenn man mal von der Groß- und Kleinschreibung absieht. Das ist bei einem chinesischen Produkt nicht selbstverständlich. Ich habe 2 Scheren und mehrere Messer geschärft. Das Ergebnis ist gut. Ideal wäre es , wenn man jetzt noch etwas hätte , um die entstandene scharfe Kante ganz leicht zu "brechen". Sonst wird die Schneide zu schnell wieder stumpf. Aber das ist eher was für Profis. Natürlich sollte man nicht versuchen damit gezackte Messer zu schärfen. Die mitgelieferten Handschuhe (Größe L) sind selbst für meine nicht so großen Hände zu klein. Für die meisten Frauenhände sind sie wahrscheinlich i.O. Fazit : für den normalen Haushalt gut zu gebrauchen und jederzeit zu empfehlen. PS : ob das Teil nach mehreren Jahren auch noch gut schärft , kann ich jetzt noch nicht beurteilen. Das wird die Zukunft zeigen.

The rough grinder seems to work well. It's hard to tell if the other two are doing anything. They don't seem to make the blades any sharper. No idea at all how to use the scissors sharpener part. The instructions are unclear and totally meaningless and guessing does nothing to help get the scissors sharp.
