A resharpened DiATOME knife has the same length, an identical cutting edge and carries the same guarantee of quality as a new knife. During resharpening a knife may be reworked into another type.
The ultra Diamond Knife is now available in Jumbo with 35˚ and 45˚ angles, and in 2.0mm and 3.0mm sizes. These knives are well suited for serial sectioning in 3D reconstructions and STEM.
