Mercer Culinary Double Diamond Manual Knife Sharpener

great product

Works perfect.

I am a professional cook and needed something to sharpen my knives. I’ve tried wet stones and I don’t like them. This works well. My chefs knife was dull. I used this sharpener and took it to work and my boss was impressed with the edge. It is easy to use and gets the job done.

PRO - Made in USA. Branded as “Mercer” (excellent maker of top quality knives) this sharpening tool is actually made by the company behind “Chef’s Choice”. Dull knives are quickly sharpened, but you MUST read and follow the directions to get top results. CON - Works best with thinner blades. Pocket or hunting knives with thick blades are a challenge, and you cannot sharpen scissors at all.

Great sharpener! Looks to be a decent quality unit. Just run the knife through a couple of times and its sharp again. Very dull knives easily sharpened by running them through one slot and then the other three or four times each. I usually spend five or ten minutes hand sharpening one of my knives with a three or four part whetstone kit. This is so much easier, faster and its done in just a few seconds.

Great for clean edge Knives and serrated knives. Easy to hold and simple to use. Comes with instructions that are easy to follow. Sharpening slot and honing slots are numbered so there's no confusion. Highly recommended.

I have had this sharpener since 2021 and it is still excellent. It keeps my knife set very sharp and its super easy to use.

This works amazingly well. Sharpens knives super fast and oh so sharp.

It is a premium knife sharpener and so it costs more than normal but it is worth the extra cost. I have just bought Mercer knives and so they don't need sharpening yet but I did have a cheap, blunt, well used, old carving knife to test this sharpener with. As per the instructions, I ran it through section 1 for 20 times to coarse it. Then I ran it through section 2 (the fine section) for 6 times to sharpen it and it came out sharp! I was astonished. If it could make this knife sharp again then it can make any knife sharp again. It's very easy to use, comfortable and solid and I am delighted with it

Much better than those sharpeners which come with the knife sets. I have a great set of Mercer knives and this is perfect. I can keep them all sharp.

Wenn man sich an die Anleitung hält und bei sehr stumpfen Messern etwas Geduld mitbringt, funktioniert das Gerät sehr gut. Sehr kurze Messer können allerdings nicht geschliffen werden (Obstmesser sind aber noch OK). Alle meine größeren Küchenmesser bekam ich sehr scharf. Meine Messer sind aber auch nichts besonderes, so dass ich nichts sagen kann, wie sich Messer mit hochwertigem Stahl verhalten. Gezackte Klingen hab ich auch nicht getestet. Insgesamt bin ich sehr zufrieden. Es ist eine große Verbesserung zum Wetzstein, mit dem ich vorher gearbeitet habe.

Good quality and sharpens very well

Easy to use. Sharpens all our knives ! Love it!
