ultra 35°
The ultra 35° knife is the standard knife for the majority of applications in both biological and materials research. The 35° blade angle is ideal for sectioning biological specimens ranging from organ tissues to un-decalcified bone and dental material. In the field of Materials Science, the ultra 35° excels at sectioning relatively soft metals and polymers, as well as nanoparticle filled polymers, brittle metals such as catalysts, crystals and semiconductors.

ultra 45°
Like the ultra 35°, this is a general use knife with good sectioning and durability characteristics. The 45° blade angle knife replaces the old 55° and allows for better sectioning of ceramics and other hard, brittle materials.
