It is the only domestically produced diamond knife for ultra-microtomes.
We have received the business transfer from Sumitomo Electric and changed our name from "Suminife" to "Shimnife." However, we continue to uphold the quality and rigorous shipping inspections, manufacturing as the only domestic manufacturer. We do not offer regrinding or replacement sales of conventional products, but we keep prices low, featuring an affordable price range and high quality. In addition to the conventional series, we have also started selling the N grade, which uses diamond of gem quality and is available for replacement sales. If you have any feedback or requests regarding the knives, please do not hesitate to let us know.
