Serving since 1982, Micro Star enjoys long-standing experience with expert know-how and state-of-art equipment to facilitate the production of the highest quality and a wide range of different diamond tools and other diamond products.
Natural diamond is used for making our diamond knife, which is the hardest known mineral of excellent homogeneity as well as the abrasive hardness enables the manufacture of sharp, notch-free knife to guarantee sectioning performance flawlessly according to the knife specifications. Natural diamond’s extreme hardness and thermal properties combine to form components that are a true asset for the best price to performance ratio of an ultra- or semi-thin sectioning tool. Unlike synthetic diamond of which its hardness depends on its purity, crystalline perfection and orientation, such as polycrystalline diamond of lower wear resistance and poorer sectioning quality.
Our welding of diamond cutting piece into the knife shank is guaranteed and permanent for life. So the knife is able to clean thoroughly by washing detergent that contains no ammonia and even using 10% acetone without the risk coming from using a Styrofoam stick that will put micro-chips on the diamond edge to hasten the time to replace the knife. If any of these parts ever becomes deteriorated we will repair it free of charge. Unlike just pressing the diamond and glue it into the shank that will come loose easily upon use and not resistant to chemicals.
At the same time the diamond knife boat is uniquely anodized to dull black color producing a perfect dark background for contrasting strong and clear sectioning color to determine ultrathin section thickness.
Diamond Knife types:

Recommended for cutting sections with a thickness range from 50 to 300 nm. Available in diamond edge lengths from 1 to 7 mm. Mounted in boat style S or any other requested style.
•TYPE CW: Cryo Ultramicrotomy Wet. For sectioning at cryogenic temperatures down to -200° C using liquids, like ethylene glycol, to float the sections. Recommended for cutting sections with a thickness range from 50 nm to 1 µm. Available in diamond edge lengths from 1 to 7 mm. Mounted in boat style W.
•TYPE CD: Cryo Ultramicrotomy Dry. For sectioning dry at cryogenic temperatures down to -200° C. Recommended for cutting sections with a thickness range from 50 nm to 1 µm. Available in diamond edge lengths from 1 to 7 mm. Mounted in boat style D.
•TYPE LH: Light Microscopy or Histology. Sectioning for light microscopy or histology applications at room temperatures. Recommended for cutting sections with a thickness range from 0.1 to 5 µm. Available in diamond edge lengths from 5 to 7 mm. Mounted in boat style K, or other boat style upon request.
Exchange Any Brand
All types of diamond knives from any manufacturer, any age or size, are accepted in exchange for a new Micro Star, at the resharpening price. The new knife will be the same size as the exchange. If you want to exchange for a different size we will be glad to give you a quotation.
Your Micro Star diamond knife is suitable for an unlimited number of resharpenings. Our high precision equipment permits us to resharpen diamond knives by removing only a few micrometers from the diamond edge restoring it to its flawless original condition. This process can be repeated many times without affecting the diamond angle or edge length. Micro Star guarantees that your resharpened knife will be restored to its original new condition with the same original angle and length.
Resharpening Service For All Brands
Regardless of the knife's manufacturer, age or size, any diamond knife is accepted for resharpening. It will be refurbished to the same Micro Star guaranteed flawless quality and the same angle and size of your original knife. If these standards can not be met, a new diamond will be set at no extra cost. Resharpened knives will be reset in their original boat and box or, if you request it, they will be mounted in a new Micro Star boat of your choice, and new wood case.
