The 200mm splitters have an internal diameter of 175mm, but realistically will split bamboo up to 150mm in diameter. These large splitters will also split small bamboo with internal diameters down to about 25mm.

These splitters are not design to be hit with a hammer - they should be held in the hands and drawn down over the length of bamboo that is to be split, whilst tapping the end of the bamboo against a hard floor or wall. Alternatively, the splitters can be set up in a solid frame and the bamboo hammered through the splitter.
