Bo and jo staffs
Training staffs differ in more than length. Diameter, weight, material and construction also matter. A jo is shorter than a bo, a three-section staff has linked sections, and Cold Steel Training Staff uses polypropylene. These products are not interchangeable and must match the discipline and class rules.
The red oak jo measures 127 cm with a 2.5 cm diameter, while the white oak bo measures 183 cm with a 3 cm diameter. The three-section staff uses 67 cm sections. Polypropylene Training Staff measures 137.5 cm, weighs 1.18 kg and has several stated finishes.
Construction for the discipline
Choose a model in consultation with the instructor. Compare length, diameter and weight with the technique and training space. Check the links on a sectional staff, and the wood species and finish on a wooden one. Synthetic material behaves differently from oak and needs separate assessment.

- length and diameter
- weight and balance
- material and connection condition
Inspection before practice
Inspect a wooden staff for cracks, splinters and warping. Check every link on a three-section design, and look for deep cuts or deformation on a synthetic model. Remove damaged equipment. Store staffs horizontally or in a stable rack, away from moisture and strong heat.
