Presto 08810 Professional Electric Knife Sharpener, Multi/None

The Presto knife sharpener is a practical investment for any home cook who values sharp, reliable knives and wants an easy, affordable way to keep them in top condition. The sharpener arrived ready to use right out of the box, with a compact design and non-slip base. Using the sharpener is straightforward. The device features a two-stage sharpening system: the first stage grinds and reshapes dull or damaged edges, while the second stage hones and polishes. I tested the sharpener on various kitchen knives, including chef’s knives, paring knives, and even a serrated bread knife. The results were consistently impressive. Noise level is tolerable and worth putting up with for the benefit of having sharp knives! In summary, the Presto knife sharpener is a good value for its simplicity, speed, and effectiveness.

Simple to use and great results. Do practice on an old knife which will allow you to learn the proper technique and break in the stones a bit. Update: after 2 weeks of ownership and 30+ knives sharpened, I am completely satisfied with this product. I have sharpened all of my knives, slicing and serrated, and am compiling a nice set for each of my two sons who are moving out and need basic kitchen tools. My new hobby is to rescue unwanted quality knives at yard sales, and give them new lives as high performance tools. The results are truly awsome and it is such a pleasure to work with sharp tools again. Update after approximately 1 month of use. I have sharpened close to 100 knives for friends and family with fantastic results. Some of the negative comments mention the motor to be underpowered. Either the motor is faulty on their unit, or they are pushing down too hard. A very light pressure works best. I would again recommend using one old knife to practice on, which will also break in the stones and perhaps reduce any over aggressive grinding. It is important to position yourself so that you are pulling the knife in a straight line towards yourself to keep the knife along the guide and at a consistent angle to the wheel. Since this is done at a slight angle to the unit, I move my body left or right accordingly. When I am using one of the sharpening slots, I angle my body so that my shoulder and arm are in line with the direction of knife motion. I also count the number of seconds that it takes me to complete the motion to make sure that I am not going too slow or too fast. So for an 8" blade, it should take me about 4 seconds to do one pass. For knives which have a curved tip, you have to raise the handle as you are pulling the tip across the stone to get the proper grind. On a long knife, I often will steady the tip with my other hand until it reaches the back of the unit. It also helps to have a good high intensity light to see the edge for inspection and to see the wheel that you are using so that you can locate the knife precisely. I work in the medical device industry where we sharpen surgical needles which penetrate human tissue, so I am very familiar with what a good edge looks like. I also have a 10x loupe which makes edge inspection very easy. A dull edge will reflect light while a sharp one will not. So if you have a light directly over the edge, if you see specs of light reflecting back at you, that means that those areas are not yet sharp. If you can get a hold of a magnifier, hold it close to your eye, steady your hand by resting it against your cheek, and move the knife towards the magnifier until it comes into focus. Most people hold the object to magnify at arm's length, and move the magnifier until it is in focus, which is incorrect. If used properly, you will have a larger image to inspect. Under magnification, the edge has micro serrations which make it very sharp. My company used to polish our needles so that they were very shiny with a smooth edge, but after developing a test for sharpness, we realized that a dull surface with a micro serrated edge is much sharper. We now use a process which keeps those micro serrations. When I am done sharpening a knife, I pull it very lightly across a finger and can feel it "biting" into the skin. Scary sharp! I have also read on some knife forums that grinding an edge can de-temper the steel and make it weak. I reached out to one of my Metallurgists and was told that unless I can see visual heat lines, which I do not, de-tempering is not occurring. Although when sharpening stainless steel I do not get any sparks, carbon steel does spark a little, which is also a good test to see what type of steel it is if you are not sure. I recently bought a Vintage 10" Chef's Knife which was advertised as "stainless" but it had some light staining on the blade so I suspected that it was made from carbon steel. It did spark during sharpening so this confirmed that I got a carbon steel knife and a real find! Now, some purists will argue that hand honing gives the best results. Perhaps, but I am not collecting priceless knives, but merely buying great knives and turning them into fabulous kitchen tools in a fraction of the time that it takes to hand tone. This sharpener is one of my favorite tools.

I’m giving the product/company the benefit of the doubt thus 4 stars because the sharpener worked as hoped. Did a great job on our old knives. My issue is the sharpener was clearly returned and repackaged. If I had known I would not have purchased just because of mixed experiences with returned and vetted products. See pic of the interior packaging. Written instructions could be better but the video on the product purchase page was very helpful. Wouldn’t buy from this company again unless assured not buying returned product.

The design on this thing is nice. It it nice and strudy. I has 3 steps on sharpening your knifes. Easy to install and use. Make my kitchen knives very sharps. HAs the ability to sharpen thick and thin knives which is very nice.

Very impressed, indeed! It uses a 3-step process; step one is a basic rough griding wheel, step 2 is a finer grinding wheel and step 3 is a polishing wheel. The finer and polishing grinding wheels have adjustable guides you set for thin blades, regular kitchen size blades and cleaver type blades. I sharpened three kitchen knives and two folding pocket knives, each pocket knife having a half-serrated blade. I recommend 3 - 5 passes over each blade using each one of the wheels, alternating each side of the blade per pass. VERY SHARP results! NO BURRS! No gouges or rough blade, just a very sharp blade, bringing new life to old, worn out blades. I highly recommend this product if you have become thoroughly disgusted with your once-sharp knives! (P.S. I used it on high-end, medium-end and low-end priced knives.)

Does a great job. Hubs had to sharpen every knife he could find to test it on different thicknesses and old dull blades. It sharpened some that seemed hopeless.

Semplicemente non può essere usato in Europa. Prodotto per il mercato USA: va a110 Volt. Ma il venditore mi ha informato solo dopo aver accettato l’ordine e incassato il costo. Annullare l’ordine è stato un calvario. Solo l’intervento di Anazon ha risolto, ma ci sono voluti molti giorni e molte interazioni. Difficilmente, dopo questa esperienza, farò altri acquisti su marketplace

Moteur un peu faible mais aiguise bien si on ne force pas. J'apprecie qu'il aiguise les couteaux a dents aussi. Pas encore essayé les couteaux céramique.

It exploded on first use. And blew a fuse. Took me forever to get internet back. It is a good product but only for US use. I had an adaptor but did not know I need s transformer. Thank you Amazon as you left no indication of the type of plug the product comes with. Nor the instructions inside the box were very clear. I am soo disappointed. I would buy it again as I am in dyre need of one but none of the other products specify what type of plug they come with.

A really very good product which will give you instant sharp knives in one go. If you're an Indian you will face the voltage problem like how I did and then spoilt the product the company however didn't not inform me which regulator to use .

Das Spannungsnetz in der EU ist zu stark dafür. Hat mir direkt den Motor zerstört. Rückgabe ist auch unnötig kompliziert
