Below we have translated & published a handful of the kind letters our customers sometimes send to us spontaneously. Sometimes however they are a response when they have received the question of what they use our sharpeners for (not always obvious). The most common letter we receive however is quite spontaneous and have some variant of the following:
Hi, I have used one of your sharpeners for fifteen years now and though it still works it’s beginning to loose it’s bite and think it’s time to purchase new one. How can I do that?
Sven Nyström – Ukulele builder
Hi, I’ve used my double sided professional now for 10 years and it’st about time to get a new one. Can I purchase directly from you?
I build musical instruments on my spare time, mostly ukulele and some guitars. I have a pile of Japanese whetstones for chisels and planer steel, but it happens very often that I take the diamond chisel for faster sharpening directly at the workbench. And then it is so good to bring with me if I travel anywhere with the tools.
Robert Harlin – Clock maker at Tidlösa Ur
I want to thank you for your excellent diamond sharpeners, the best I have found. I just bought a new one when I started my own watchmaking company and quick teaching at Watchmaker’s school where I had the old sharpener from you. We have recommended your sharpeners to colleagues abroad and some in Switzerland, that have been very impressed and bought them as well.
The sharpeners are particularly good for cemented carbide sticks for hardened steel turning. But also to sharpen chisel blades and short mission shafts.
It may be a good idea for you to contact salesmen and watchmakers, more should try your products and drop primitive grindstones.
Patrik Sjögren – Clock maker at GoS Watches
I use it for example. quickly grind off extra material on parts I work with.
An example is when I shortened an assignment shaft (hardened steel) and want to level the end. But in common, it is a brilliant tool to remove material on steel details. I got to taste it after using it at the watchmaker’s school many years ago. It was the only thing that worked well on carbide inserts for the lathe as well, so that is another area of use
Michael Bergquist – production manager Delsbo Chark
Our sausage chopper is 325 liters, and after each day we sharpen the knives with the Dianova sharpener. This means that we do not have to dismount and grind them to the same extent as before. This saves a lot of time and also means that we can maintain a consistent quality of the products from day to day. Previously, we dismounted and sanded the chopper knives at least once a week in our big grinder but since many years now we use diamond sharpeners and can because if this keep the sharpness good for about three weeks. We think that’s good. A good and simple solution for keeping the chopper sharp. They work well with other knives as well, but for our part, it’s the sausage chopper we use them on, mostly…
Sven Isaksson – owner Swemek Älgarås Mek. AB (manufacturer of high precision parts for Air guns)
I want to order 4 sharpeners of type Classic Long
I would also like to take the opportunity to advise you to market your sharpeners to the engineering industry and especially to us as automatic lathes. I have used your sharpeners for about 15 years to sharpen Carbide tools and also when manually grinding special tools and odd radii. In short I would not have coped without this whetstone. I have tried many others but nothing comes close to yours.
