Expensive, but will make you realise your knives weren't sharp before!
For a long time I've been using the "drag-through" style of sharpener on my kitchen knives. Some of them are quite expensive, and I've noticed two bad things happening:1. the initial edge grind that they came with is disappearing or has gone, leaving a fairly thick edge that doesn't really sharpen2. where these is an edge, it is ragged and catchy.I did quite a lot of research (meaning: I watched a lot of videos!) and initially I thought I'd get a whetstone (an oilstone or a waterstone more specifically), but I found that the good ones are expensive, you need several, and they wear away and have to be "dressed" with a special tool which wears them away further.As I'm not a knife-maker or a professional sushi chef, I looked for an alternative, and found diamond stones. These are much tougher in that they don't really wear away (although they do gradually lose their diamond coat over a long time), but they also have the advantage that they're more rigid and you only need a single (multi-grit) one to get your knives to a very good level of sharpness.(Knife-sharpening specialists will probably suggest you also get a leather strop and some grinding paste to finish off the edge, but I haven't done that and the sharpness I get to is still excellent).There are several good "how to use" and "how to choose" review videos of this Sharpal product online. It actually comes in two sizes and I bought the smaller; it works fine, but I would advise you to strongly consider getting the larger one if you have chef knives to sharpen, for a few extra pounds, as it will be a little easier.This one is fine, nevertheless, once you've mastered the technique, which took me a few hours at most.The stone comes in a very strong, quality storage box which is also the non-slip stand to hold it in when sharpening, having a large soft rubber base. It also has a magnetic angle gauge that you can attach to your knife to help you maintain any of 4 common blade angles.The instructions are fairly clear, although I would recommend looking for a tutorial video to really get the idea of how to sharpen.My other tip would be to start on a knife you're not too worried about making a bit of a mess of initially (although you will be able to adjust it once you get the hang of the technique!)Now that I am fairly practiced at using the Sharpal diamond stone, I can say that it is very fast to take even a blunt edge to a well-ground angle, and then to a razor-sharp, moderately polished cutting edge. You can probably do that in 10-15 minutes. With whetstones (which I've used in the past), you'll need several, and it would likely take 3 times as long.Remember to wash and dry the diamond stone to clean it occasionally; you can use it wet or dry. Wet will give you a satisfying metallic slurry very quickly as you use it!My tip here is to be careful not to rub your fingertips repeatedly on the stone as you sharpen, because you will literally remove your fingerprints!I've now sharpened most of my knives to better-than-new edges, and I've also sharpened scissors pretty effectively. Again, this is using the smaller model, and it would be even easier with the larger one.Overall, this has been a great purchase, and has really improved the safety and sharpness of my kitchen knives, and also improved my enjoyment of cooking because it has eased and increased the speed of my chopping and preparation significantly!I really recommend this Sharpal stone; give it a little time to learn how to use it, and you'll be cutting paper-thin slices of tomato just like they do in online videos to demonstrate how sharp your knives are!

Very easy to use
I received this today, I am particularly bad at getting any sort of an edge on my pocket knife and have tried a few options. Having seen this sharpening stone, read the reviews and the fact that it was in the sale I decided to try it. Within 5 minutes I had a really sharp knife again. The diamond sharpener is solid, the carry box contains it and the angle guide makes getting the best edge easyTry it, you won't regret it

Well worth its money
Do not make the mistake that I made by trying one of the cheap far east ‘pull through’ sharpeners. They do not work and will ruin your knives! If you inspect the blade after using one of these cheap sharpeners you will notice parts of the blade become serrated and these devices just make it worse! So, I bought this SHARPAL diamond set (Coarse and Fine) to try to repair my expensive knives and they work like a dream. You do not need to use any lubricant but you do need to clean the stone with water and a nylon scrubbing brush when you have finished. If you do not do this as some reviews state the stone becomes discoloured – simply rust forming from debris left from the sharpening process. Dry the stone before putting it in its very handy case which also acts as a non-slip base for sharpening. It took me a bit of time with the coarse stone to remove the earlier damage but a few passes on the fine stone and the knife was as good as new. Highly recommended.

Really good value for money
This diamond whetstone good quality, and good value for money. It seems to have good and consistent diamond size, and good bonding of the diamonds to the base. The whetstone seems to be flat, and you will have an enormous problem changing that. The base is a good weight, and the box makes a good, stable platform for the whetstone when sharpening. With care this should last a lifetime. The angle guide is of limited use. With practice you will be able to get shaving-sharp edges on most blades or tools.

Compact and convenient
Not too bad. Does the job. It definitely gets an edge back on your knife. I use it along with a diamond steel in a commercial kitchen. Very convenient not having to soak it first. I would say that the magnet on the guide block could be stronger though as it moves quite easily and the slip resistance isn't great on a stainless steel bench. The size is also convenient, it fits into my knife box and ready to carry on it's compact case. It has got a bit of weight to it.

Not cheap but *very* effective
Very effective. The double-sided block and diamond grit gets the knives very sharp. I so use a leather strop and diamond polishing compounds to really get the finest edge, but actually that's not completely necessary. Just using this gets a very sharp edge. The little block is somewhat effective at holding the blade at the correct angle, but actually I found it nearly as good doing this by feel. Some blades (particularly large or thick ones, or ones with unusual dual-bevel edges etc.) don't really work with the aligner, but you can still get a good edge on them. I've also used it for sharpening scissors, garden tools etc. so it is quite versatile.

The best one I have had
Over many many years as a motor engineer I have had quite a few sharpening stones. This is by far the best I have had.

Sehr gute Diamant- Schleifplatten von Sharpal
In der Küche kann man auch mit einem scharfen Rasiermesser Tomaten, Möhren, Paprika oder Fleisch schneiden. Nur ist dieses scharfe Rasiermesser leider sehr schnell völlig stumpf und unbrauchbar.In der Küche benötigen wir also eine andere Art von Schärfe, die besondere Schärfe von Diamantschleifplatten. Es ist eine Schärfe, die lange anhält und sehr schnell wieder scharf gemacht werden kann. Eine solche Schärfe suchte ich schon lange, jetzt habe ich sie endlich gefunden. Es ist der SHARPAL 156N Diamant- Schleifstein Abziehstein. Ich bin damit völlig zufrieden.Mit diesem zweiseitigen Diamant- Schleifstein konnte ich schnell alles scharf bekommen, was es in meiner Wohnung nur zu schärfen gab. Ein bisschen Geduld braucht man aber doch. Der siebenteilige Messerblock mit Küchenschere von Zwilling wurde ungewöhnlich scharf. So scharfe und für die Küche gut geeignete Messer habe ich bisher noch nicht gesehen. Alle 8 Papierscheren und Manikür- Scherchen aus der Wohnung wurden schnell wieder scharf. Meine fünf Stemmeisen wurden endlich mal richtig in Form geschliffen (mit der groben Seite) und sind nun alle sehr scharf. Mehr Schärfe brauche ich gar nicht.Um ihnen die endgültige Schärfe zu verleihen, habe ich mir bei Amazon das Abziehleder „BeaverCraft LS2P1 Schärfset“ mit Schleifpaste für 8,95 € gekauft. Das Ding ist gut, wenn man eine etwas höhere Schärfe benötigt.Meine 340 Mark teure professionelle Haarschere habe ich damit allerdings nicht geschärft. Auch ein Rasiermesser darf man damit nicht schärfen. Dazu benötigt man viel Zeit, superteure Schleifsteine, Maschinen und einen guten Fachmann.Ich bin mit diesem Diamant- Schleifstein von Sharpal sehr zufrieden und kann diesen jedem, auch den Profis, wärmstens zum Kauf empfehlen. Er ist viel schneller und viel besser als eine teure schwedische Tormek oder als meine teure Messer-Schleifmaschine mit Diamantscheiben von Graef. Ich glaube auch, dass der Sharpal Schleifstein sehr lange Zeit gut bleibt und schärft. Im Internet, auf YouTube, schleifen immer mehr angesehene Tischlermeister ihre Hobel- und Stemmeisen mit solchen Diamant- Schleifsteinen.

Şahane
Ürün oldukça.kalın kısmı çok hızlı şekilde bıçağın ağzını şekillendiriyor.inde kısmı da aynı şekilde kısa bir sürede daha ince bir ağız veriyor.ancak daha da ince bir taşınızın olmasını öneririm, 3000-4000 civarı.Bu ürünün kaydırmaz tabanlı kutusu aynı zamanda taş standı oluyor ancak çok iyi oturmuyor.yine de işlevsel.Bıçaklarınızın boyutuna göre biraz daha büyük bir modeli var (162N). O da tercih edilebilir.İnternette çeşitli forum ve bloglarda bu ürünün mikroskop altında incelemelerinde, elmas parçalarının boyutlarının çok iyi ve uyumlu olduğuna ilişkin yorumlar bulunuyordu.son kullanıcı olarak bu incelemeyi kendim yapamasam da bıçaklarımın ağzındaki çiziklerin boyutlarına bakarak bunun doğru olduğunu söyleyebilirim

Fantastisk
Bästa slipstenen jag någonsin använt. Inget slitage på diamantytan upptäckt efter 2 år.

Nicely aggressive
Very nice and aggressive diamond stone, I can finally easily sharpen our knifes myself. It takes a bit of practice and I don’t reach razor sharp yet, but that seems to have more to do with my skill level than with the stone :)
