With a technical innovation, the nail scissors of the Solingen brand Stahlkrone surprise - where else than from the famous cutlery city of Solingen can an innovation for manicure instruments come? In contrast to stainless steel blades, those made of carbon steel are particularly cutting, as they have a self-sharpening effect due to the material. These scissors - although made of stainless steel - are also self-sharpening. This can be seen from the colored shank, which is not only due to its appearance, but is the result of a high-strength titanium nitride coating, as is also used in the tool industry. This makes the surface of the shank and cutting edge significantly harder (about twice as hard) and more wear-resistant than that of the other shank and straightens its cutting burr every time it is opened and closed. According to a test conducted by the VPA testing institute in Remscheid (No. 170449/13067), the uncoated model wears out after about 50,000 cutting operations, while the coated nail scissors still show full cutting performance even after more than 100,000 cuts. In addition, the tip is so fine that the scissors can also be used as cuticle scissors.
