Traditional bokkens, which are wooden swords used for training purposes, are typically not sharp. They are designed to simulate the weight, feel, and balance of a real sword while minimizing the risk of serious injury during practice or sparring sessions. Bokkens are usually made from solid hardwood, such as oak or hickory, and their edges are usually rounded or beveled to reduce the likelihood of cutting or piercing injuries.

However, it's worth noting that there are variations of wooden swords, such as suburito or tachi bokken, that may have thicker and heavier blades. While these blades are still not typically sharpened to a cutting edge, their increased weight and thickness make them less suitable for sparring and more appropriate for strength and conditioning exercises.

If you are training with a bokken or any martial arts weapon, it's important to prioritize safety and use appropriate protective gear. It is always recommended to receive proper training and guidance from a qualified instructor to ensure you are using the weapon correctly and safely.
