• In some jurisdictions, a shinai may be classified as a weapon – check local laws before purchasing or traveling with one.

Tips for Buying and Maintaining

• Apply walnut oil regularly to improve bamboo flexibility and extend the life of the sword.
• Never strike hard surfaces – shinai are designed for padded opponents or kata practice.
• Inspect the leather grip and tsuka before buying. Poor finishing can reduce comfort and handling.
• Invest in a higher-quality shinai if you plan to spar often or use it in a dojo setting.
• Store it in a dry place and check for splinters or loose tips after each session.
