Great product! What a time saver!
There are probably plenty of raving reviews about this product but this review is more geared towards 'how to use' properly and other views that aren't discussed. I've used it for work knives, kitchen knives, small carving tools and work swords (yes, swords). I've fixed 2 softer metal blades that I thought were going into a recycling bin. It is quick to setup, fairly easy to use and gives good, work fast results. Granted I still prefer stones and plates for my favorite, cherished tools but using those takes time, prep work and lots of work along with clean up and proper storage. I can get a better edge with them but that's because I can control the abrasive removal process easier. As always, wear protective gear as the removal process will create metal and abrasive dust. I always wear safety glasses and cut resistant gloves for larger blades. The WSKO edition is abrasive. It can take off more than you wanted and you will go through belts in little time. It does require some skill and for whatever reason do not test it on your favorite blades until you are comfortable. Even when using older sharpening processes I usually use a test blade before reaching for my good blades. With the WSKO it can take some time before you get a hang of it. I couldn't remove the bur on my first few attempts and I was tempted to just finish those with my nicer stones and polish but keep at it. Using a finer belt and switching edges works the best for the bur. I usually go slow and yes stop the unit early when you reach the tip. I've used this for sharpening my Condor Dadao and ZOMG even the awkward (long) pull gives me undeniably fast work sharp results compared to older methods. I will be purchasing the work tool attachments in the near future but for edged tools that you don't put down often it will save you time so you can continue to do (you got it) work. A huge advantage if you're out with the task and need a quick sharpening. If they had a battery powered version (that was also pluggable) then this would be the only sharpener I'd need. I'm not a hunter but I do butcher livestock. This would be undeniably useful for that alone or for a hunter who does not have access to electricity. *HINT HINT Worksharp, do it!* Overall, if you're looking for sushi stupid crazy bragging sharpness this could achieve it with enough practice. It'll still do it faster than plates/stones/polish but it may take off more than you'd like. It will go through belts sooner than you think and the sharper you want your blade(s) the more you'll pay for it. That's the trade off though and any mechanical belt sharpener will require new belts. I suggest purchasing a backup set and some polish for the hack (works pretty darn good). Even with some after thoughts I cannot believe how much time is saved. What usually took me a daylight's worth to finish a bucket of bladed tools is shortened to a few hours (sharpening 20"+ swords with plates, stones, polish is not as easy as it looks). If time is money or important then this is definitely worth the investment.

Finally, a knife sharpener that works!
Excellent sharpener. The oval edge produced by the sharpener means sharp edges last longer. Not just a little longer, but a lot longer.

Super fast sharpener!
I really love this sharpener! I was able to finish an entire kitchen knife set in less than an hour. Anything by Worksharp is well built and does a great job. Its easy to set up and its not much of a learning curve so you can get going pretty fast. I just wish it came with a carry case, otherwise its a wonderful tool!

Not a dull knife in the Lodge!
Bought this after a hunting buddy brought his along during the season, worked so awesome I had to get one! Can remove nicks or just bring a dull blade back. The pocket knife guide really does start out by asking if the blade is "Trashed"!? It can remove a lot of steel in a hurry so be sure to follow directions and change the belts to hone it properly. Plug and play with easy to follow belt and speed guide. Haven't tried it on hatchets and axes yet but would certainly be capable!

Just as advertised! GREAT sharpener for us commoners. (Not for a Michelin-star chef)
This is a great sharpener! There are pros and cons to having an electric/powered sharpener, versus the manual models that clamp to a workbench and have a constant-angle arm. The obvious upside is that the powered sharpeners are MUCH FASTER to use, (and of course require less effort). The downside is directly related to the upside of speed: While it's faster and easier to sharpen a knife, it's also faster and easier to ruin one. Depending on what you use your knives for -- and what kinds of knives you have -- this is a no-brainer to purchase or pass. BOTTOM-LINE ADVICE: Use this sharpener for your every-day kitchen and utility knives, (and outdoor tools, as well as woodworking tools that do not need to be LASER precise). But if you have $400 knives or use precision tools to carve details into wood, then get a manual system for those. SHARPENING ABILITY. It's as advertised. You can get your knives razor/mirror sharp, and very quickly. In this respect, it's just as good any other sharpener. They do include a 6000p belt, which is similar to a leather strop, but I did buy an additional leather strop and compound to go from razor sharp to the polished effect -- you won't necessarily notice the difference in cutting in the kitchen, but strop polishing makes a knife ever-so-slightly sharper, and keeps it sharper a little bit longer. HOW YOU CAN RUIN YOUR KNIVES WITH THIS -- OR ANY ELECTRIC -- SYSTEM. 1. First, there is the human tendency to push down at the base of the blade -- closer to the handle -- then to gently let up on the force as one pulls the blade through the sharpener. This has a cumulative effect of removing more metal from the knife at the base near the handle, even to the point of creating a concave curve there. 2. Second, it is easy to "round off" the tip of the knife, so that instead of coming to a sharp point at the tip, the tip becomes more like a small rounded blade. WITH PRACTICE, you can lessen those tendencies. Start with older, cheaper, more expendable knives, and practice. I was well aware of these tendencies, and I consciously compensated for them, and I still got a slight bit of base curvature and rounded tips on the first several knives I sharpened. THE ONE DRAWBACK OF THIS PARTICULAR DESIGN is that the guide to keep your knife at a constant angle is just not good. It's a plastic guide, (which amazingly is not even entirely flat), and it requires the user to manually hold the blade flat against the guide on one side, while sharpening by the belt on the other. This is harder to do that you might think. And even after much practice, I still swerved in and out of square against the guide. When sharpening short or narrow blades -- like paring knives or fillet knives -- the guide is completely useless, and you are essentially free-styling against the belt. AGAIN, this is much faster -- and just as good as -- free-styling on sharpening stones, but you need a very steady hand. I have a Henkel 4-star paring knife, and I did go ahead and use this machine on it, (to great effect), but I'm still hesitant to use it on my 4-star Henkel 8" butcher knife. (I might after more practice). Bottom line, if you are a collector of fine, rare, historic, or decorative knifes, -- like some of my buddies in the south who have major-league pocket knife collections -- then this is NOT the sharpener for you. If you are a chef or artist who uses blades to carve intricate details, and your blade is your livelihood, then stick with manual sharpening. But if you use your knives in the kitchen, or you have sets of knives for a restaurant that are not top-of-the-line investments, and if you want to sharpen axes, mower blades, and chisels for mortising, then I whole-heartedly endorse this machine, and would argue that it is way underpriced. As a non-professional at-home cooker, home handyman, and amateur woodworker, this is a great deal and a no-brainer. Most of my kitchen knives are middle-of-the-line, and I would just as soon buy another $30 blade than to spend two or three hours to manually sharpen one. With this device and a leather strop, I lined up about a dozen kitchen knives, and from start to finish, spent less than two hours getting them sharper than they have ever been. And it is true that this curved-bevel sharp will last longer than before. The cost of this machine was about $140, whereas the cost to replace those knives would have been over $500. They will probably not need re-sharpening for a year or more. I can live with a little added curvature and bit of a rounded tip.

日本の電気製品のプラグと形状が違います。 日本の電気製品のプラグの差し込み部分は、両側ともまっすぐで同じ形状ですが、この製品は米国仕様?で片側の差し込みの先端が丸く広がっています。要するに日本のコンセントには差せません。このため電圧的には問題ないのかもしれませんが、結局アップトランスを購入して使っています。 ナイフの先端のカーブした部分を除けば刃は簡単に砥げますが、感動するほど便利に良く砥げるということは無い気がしました。替えのサンダーベルトの購入も簡単ではないようです。購入するなら日本国内の総代理店が出来てからの方が良いかもしれません。 購入して10日少々で2,000円以上値下がりしているんですけど・・・Amazonでの買い物って精神衛生上よくないなぁ

Compre este artículo porque promete afilar cuchillos muy bien, si eres alguien que le gusta afilar en piedra pero le da mucha flojera, este producto es para ti. Tardé 15 minutos en afilar 5 cuchillos usando 4 bandas diferentes, todos quedaron mejor que de fábrica. No hay forma de equivocarse, el afilador trae instrucciones y guias para que cualquiera sin experiencia obtenga grandes resultados. Hay una gran cantidad de videos de Youtube de como usar el worksharp Kenonion y ademas estoy en la espera del accesorio opcionar para afilar sin guias.

I purchased this and immediately upon receiving it began to sharpen all of my knives. I am very particular about my knives so I never let them get dull or chipped. I have been using several different types of sharpeners over the years however I love this one. I have now put 38 different types of knives (total of 60 knives) through this sharpener now. My hunting knives were slightly dull before starting and the rest were of fairly good sharpness. Below are my impressions. PROS: Very consistent edge angle that is VERY easy to duplicate every time. The angle adjuster is so simple to use, it never moved on its own and is very easy to see and feel. The machine motor stays consistent RPM and does not slow or minutely vary in speed when pulling a blade through. The belts are super easy to change and having the belt centering adjuster is a great feature that is much appreciated. The knife angle guide is super easy to remove when doing gut-hook edges and then to re-install afterwards. CONS: The little plastic roller wheel on each pull-through guide are of a soft plastic that the knives will cut into even with light pressure. The speed adjuster is not in a good spot, every time I pull and release the trigger it slightly creeps up in RPM as the wheel ever-so-slightly rotates when I place my finger back on and pull the trigger. It should be a 4 or 5 indexed speed setting wheel on the motor housing somewhere, no need for it to be on the trigger and it would greatly help if indexed. I personally found the angle of the handle to be very flat and after an hour of using this tool my wrist started to feel the strain due to the angle. I do realize that many will not spend over an hour straight using this tool and I typically won't either however I wanted to put this tool through its paces. I read that many people had issues with it scratching their knives, this I can only assume is do to improper use. I was initially a bit worried about it scratching my knives due to so many comments about it, so I started with a few hunting knives. I carefully followed the simple included use instructions and I never so much as put the faintest of scratches on any of my knives. I have a really expensive set of Wustof kitchen knives that I sharpened every one with this tool and just like all other knives I put through, they came out the same as when first purchased from the manufacturer. I used the 6000 grit belt to finish off the edges on all of my knives as I like an incredibly sharp edge on every type of knife I own and the edge looks like polished chrome this does such a good job. Even sharpening the gut hook on several of my hunting knives was a quick and easy task that now has them razor sharp again. I also read about many people rounding the tips off their knives, again, if you read and carefully follow the instructions you will always end up with razor sharp pointed tips. Even on my fish filet knives the tips are still like a needle, you just need to stop the belt before pulling the blade completely off the belt. I gladly give this a 5 star rating and not only would I buy this again I have already been recommending this to friends and family. Worth the price considering what just a good set of sharpening stones will cost and those are much more labor intensive to use correctly.

Habe jetzt schon mehrere Messer geschärft und jedes wurde rasiermesserscharf. Natürlich kommt es auch auf den Stahl an und deswegen werde ich das eine Billigmesser daß ich noch habe entsorgen, natürlich wird es scharf... aber nicht lang. Der Work Sharp, ein Traum zum Messer schärfen, exakt immer im gleichen Winkel schleifen, zuerst grob vor schleifen dann mit dem mittleren Band und zum Schluß das Messer polieren mit dem feinen Band.
