I want to cut a wooden stick (for practicing martial arts). What kind of material is the best?

The wooden sticks used in martial arts are generally made of ash, which has good feel and elasticity and is not suitable for chopping. The length of the stick is based on a person's eyebrows, that is, the eyebrow gas stick. The thickness of the stick depends on its own feel. If it is too thick, it will fall off easily; if it is too thin, it will become hard. The thickness of the root rod should be consistent, the cross sections at both ends should be slightly polished, and the rod body should be polished repeatedly with fine sandpaper to make it smooth and burr-free.
