Goodbye whetstone...almost!

remote camperNovember 23, 2009✓ Verified purchase

...and that is purely because I am a traditionalist when it comes to sharpening knives. I spend a lot of time outdoors and sharpening a knife the old fashioned way is an essential skill for every man...and sadly maybe for the woman whose man won't develop the skill. Even during a stint in the deli and meat business for 9 years, I stuck with the old methods. As often as I had to sharpen knives, only occasionally and with a lot of work was I able to get our knives really razor sharp. Other times, they were only just pretty sharp! Many people don't realize that the most dangerous utensil you have in the kitchen is a dull knife. A dull knife requires more force to do the same work. Dull knives are more susceptible to slipping and combined with the force that moved them, can still produce chilling and even life threatening accidental cuts. A sharp knife requires much less force, can cut more precisely and is easier to control. I bought this device for my son and daughter in law for Christmas 2008. They owned excellent quality knives, but they were sharp only for the first few months after they bought them. After that, I discovered they may as well have used a butter knife because that's the condition these knives reached pretty quick. The knives also suffered from the very bad habit of being stored loosely in a drawer. Consequently they had nicks in addition to just being dull. I was afraid that my daughter in law would end up with a nasty cut. The situation got so bad that instead of sharpening the dang things, my daughter in law would just buy a new knife each year! I used this device for the first time just last week only because I remained as stubborn about my son learning how to use it as I did about my own traditionalist methods. He and a buddy tried using it...without looking at the instructions... and didn't get anywhere with it. I learned very quickly that had I been smart, I would have bought one of these machines for ourselves when we started our deli business in 1994 !! It is important to read and follow the instructions to get the best service from this machine. Starting with the dullest 10" knife and using only the weight of the knife, I drew the knife blade in 10 alternating passes. This very quickly produced the burr sought in the instructions for stage 1 along the entire length of the blade. (Normally, a knife in better condition would need only a total of 2-4 alternating passes to produce the same result.) After reaching the burr stage, only 4 alternating passes (2 on each side) in stage 2 produced an edge on this knife that I could use to shave the hair off the back of my left index finger! I gave that knife one more stage 2 pass for each side and went on to the next knife. This time fewer passes...same results! My daughter in law gave it a shot with another dull knife that would only smush a tomato and produced an edge in only seconds that would cut tomatoes paper thin! She also got razor sharp results on a short bladed paring knife! Once a knife is this sharp, the machine won't be needed for quite a while. Generally, only a pass or two with a high quality ridged sharpening steel such as those offered by Forschner or Mundial will be enough to maintain the edge for months of household kitchen use. This is because the edge of a razor sharp knife becomes so thin that it will "fold over" in the shape of a J during use. The steel straightens the edge and restores it's razor sharpness with just a few VERY LIGHT strokes. The vision you might have of the butcher flailing his knife 10-20 times with the steel to restore the edge is really overkill and mostly for show. The two light strokes should do it...and as quietly and lightly as possible. I have even used the bottom of a ceramic coffee cup or the back edge of another high quality knife in place of a sharpening steel, although the coffee cup will remove some material from the blade of the knife. In just minutes with this machine, we had 8 razor sharp knives and accomplished what could have literally taken HOURS to achieve with traditional methods. If you are not getting the same results with your machine, my humble guess would be that you are not using it properly. the steel in your knife is very hard or they are in really bad shape. Only as a last resort would I fault this machine. We were even somewhat saddened when we were done! Remember to store your knives in a way that keeps them banging against each other. We prefer wood blocks designed for storing knives. They can get pricey if you buy them retail. We managed to pick ours up at Goodwill for $2....a real bargain. They have them every time I go in there. ------------------------------------------------------------------------------------------------------------------------ UPDATE 11/29/2010 This sharpener worked so well on my daughter-in-law's knives that I took one of mine that I have been maintaining the traditional way on this trip to sharpen it on her sharpener. The knives I did for the above review needed only touch up sharpening and was done with them in a few seconds. My 10" kitchen knife, on the other hand, needed a lot of work. I was getting nowhere on the 1st stage and thought I might be using it wrong. In reality, the angle I had sharpened mine to manually was incorrect and the machine was putting the correct edge on them. I lost count of the # of 1st stage passes made to get the burr, but when I did, a few passes in the 2nd stage had the knife razor sharp. If you are not getting anywhere with this sharpener, you need to make sure you are following the directions and be persistent to get that "burr". Then you will be only seconds away from the sharpest edge you've ever had... Read more

Works great

E. WolfJune 30, 2024✓ Verified purchase

It takes quite a product to make my husband comment about it, but we hadn't had this very long before he said "hey, by the way, that knife sharpener works great!". That's a good enough vouch for me, honestly. I have since watched him use it (so I didn't mess it up) and used it myself, and it does seem to do a good job. We've used manual knife sharpeners which do work, more or less, but this one is much more dummy-proof, which is great when you're clueless like me. Quicker too, as you'd expect. It has gently flexible guards that guide the blade at the right angle against the grinding wheels. It's a little noisy but I wouldn't expect anything less for a knife sharpener. End result is a sharper knife, so we've been very satisfied with this bad boy. Read more

Works extremely well on kitchen knives

CustomerOctober 14, 2023✓ Verified purchase

I am slightly compulsive about keeping our Wusthof kitchen knives super sharp. I have used a local sharpening service which was good but expensive. I recently bought this Chefs Choice 320 sharpener and have been very pleased with the results. It's easy to use and gives me a perfect edge. Compared to other sharpening systems or taking the full set to a pro, this unit is really a bargain. Once I have the edges really sharp I can occasionally do a couple strokes on the honing side and keep the knives at peak performance. Easy to use and does a great job. Ideal for kitchen knives.

Excellent Product

This is a very good knife sharpener. We have one at home and I bought this one, and another, as Christmas gifts for my kids. There's nothing better than a sharp knife in the kitchen and this product does the job. Read more

It's a keeper..........

speedracerXDecember 30, 2014✓ Verified purchase

Well, I have decided to purchase this knife sharpener from all the positive reviews here, I must admit it, that it really does put an edge and then some. The 2nd final stage really polishes and gave it an extra sharpness to the knife edges. After going through all my knifes from hunting knifes to home cutting knifes, I am impress of it's performance, it was so sharp, that when my wife was cleaning it, she cut herself by accidental and she wasn't aware on how sharp the knifes were, she is more careful when she cleans it. I hear lots of reviews on other people saying that the sharpener did not meet their results, well those that did say it did not work, my suggestion is to follow the instructions on the manual before performing the workings of the sharpener tool. With a somewhat dull edge on some knifes, I have pulled each edge of the blade side slowly pulling it towards me into each slot by counting how long the knife is in inches, if it is 8 inches, then it would take 8 seconds per side, some my vary on the edge of the knife, that's is saying on the number 1 slot of the left side, then doing one pass on the right side, it took me 3 sides per slot #1, then finishing it on # 2 slot with 2 pulls per side, wow the results was fantastic, that's just my results and some may vary with less per side of the knife blade edge. My 25 year old knifes are way better now, then sending them out to the commercial sharpeners. It's a keeper......... Read more

Excellent.

Excellent machine. Mine has served flawlessly for 5 years constant use . We're both Chefs and 2 kitchens in the house. Now the cord is shorting out , so my husband opened it up to make his repair and saw the diamond discs were pretty much worn down , so we recycled it and ordered another here on Amazon .Recommended.
