Over the years the Swiss company Diatome has been the innovator of diamond knife technology. Diatome was the first to introduce and perfect low angle diamond knives, as well as diamond knives for cryo-ultramicrotomy and light microscopy. Only Diatome can offer you 25 years of experience in diamond knife manufacturing and testing!
Knives for specific purposes
Different specimens have different sectioning qualities and thus pose different demands to the physics of the sectioning process. Examples are the developments in resins for ultramicrotomy, progress in cryo-ultra microtomy of cryoprotected and natively frozen biological samples, but also in materials research for virtually all types of materials.
Diatome has recognized this and developed a low angle diamond knife (35°) which gives significantly less compression with for instance Lowicryl embedded specimens. Diatome's technology and technical developments of today allows them to manufacture knives with the highest sectioning capabilities.

The objective in resharpening a Diatome diamond knife is to restore the knife to its original guaranteed condition (the same length and that of a new knife). Diatome diamond knives can be resharpened an unlimited amount of times due to the following reasons:
