The "new" maroon Swann-Morton No.6 Ergonomic Handle is compatible with any blade shapes included in the No.4 fitment range such as the 22 and 24. 

This range of handles is designed to maximise performance and dexterity and feature a textured surface finish for ease and comfort of grip whilst minimising fatigue.

These ergonomically designed handles are used in Histology, Pathology/Autopsy and Laboratory settings whilst they can be autoclaved to avoid any cross contamination of samples.

The handles are also colour coded for ease of recognition.
