No, polypropylene swords are not sharp. Polypropylene is a thermoplastic polymer that is commonly used to create durable and impact-resistant training swords. These swords are specifically designed for training, sparring, and practicing martial arts techniques.

Polypropylene swords are typically solid and rigid, but they lack a sharp edge. They are not meant to be sharpened and do not possess the cutting ability or edge retention of a real sword.

Polypropylene swords are primarily used for simulated combat, drills, and other training exercises where the focus is on technique, footwork, and coordination rather than cutting or striking with a sharp blade.

The advantage of polypropylene swords is that they offer a safer training option, minimizing the risk of injuries associated with sharp-edged swords. They can withstand repeated impacts and are less likely to cause serious harm or damage during training sessions.
