Kendo Training Sword: US Guide to Choosing Yours

The pursuit of kendo, a modern Japanese martial art, necessitates diligent practice with appropriate equipment, and a kendo training sword is paramount for safe and effective skill development. Shinai, the quintessential bamboo practice weapon, requires careful selection based on length, weight, and construction to match the practitioner’s skill level and dojo requirements. The All United States Kendo Federation (AUSKF) provides guidelines and regulations governing the use of shinai in sanctioned competitions and training environments. Furthermore, consideration of bokuto, a solid wood sword often used for kata practice, adds another dimension to the kendo practitioner’s armory.

Selecting the Right Kendo Training Sword: A Comprehensive US Guide

The selection of a kendo training sword, often referred to as a bokuto or bokken, is a critical decision for any kendo practitioner. The right choice facilitates effective training, promotes safety, and contributes to proper technique development. This guide offers a structured approach to navigating the available options within the US market.

1. Understanding the Purpose of a Kendo Training Sword

Before delving into specifics, it’s essential to understand the bokuto‘s role. Unlike live blades, bokuto are designed for repetitive practice of kata (forms) and controlled sparring (keiko). They are impact weapons intended to simulate the weight and balance of a katana, allowing practitioners to develop muscle memory, improve grip, and refine their swordsmanship without the inherent danger of sharp edges. Therefore, durability, balance, and proper weight distribution are paramount.

2. Material Considerations: Wood vs. Synthetic

• Wood: Traditionally, bokuto are crafted from hardwoods. Common choices include:

  • Japanese Red Oak (Aka-gashi): Known for its durability, shock absorption, and relatively lighter weight. A solid all-around choice.
  • Japanese White Oak (Shiro-gashi): More dense and heavier than red oak, providing a more realistic feel to a live blade. Can be harder on the hands during extended practice.
  • Other Hardwoods (e.g., Hickory, Purpleheart): These offer varying degrees of durability and aesthetics. Ensure the wood is properly seasoned and treated to prevent warping or cracking.

• Synthetic (Plastic): Modern alternatives constructed from high-density polyethylene (HDPE) or similar polymers.

  • Advantages: Weather-resistant, highly durable (less prone to splintering or cracking), and often more affordable.
  • Disadvantages: Can feel less authentic than wood, and some may lack the proper weight and balance. However, high-quality synthetic bokuto are improving in this regard.

3. Key Features to Evaluate

Choosing a kendo training sword should involve the consideration of several specific features:

• Weight: Generally, a standard bokuto should weigh between 500-600 grams (approximately 1.1-1.3 pounds). Heavier options are available for strength training.
• Length: Standard adult bokuto length is around 101.5 cm (approximately 40 inches). Smaller sizes are available for children and teens.
• Balance: The center of gravity should be located closer to the hilt (handle). A well-balanced bokuto feels more responsive and easier to control.
• Shape: Look for a shape that closely resembles a katana. The curvature (sori) and thickness should be consistent.
• Grip: The handle (tsuka) should be comfortable and allow for a firm grip. Some bokuto feature a wrapped grip (tsuka-maki) for added security.
• Tsuba (Hand Guard): A tsuba is not always included with a bokuto, but it’s highly recommended for safety during sparring. Ensure the tsuba is securely fitted and made of durable material (leather or plastic). A tsuba-dome (rubber ring) will also keep the tsuba in place.

4. Sizing Chart and Considerations for Beginners

User Group	Recommended Bokuto Length (approximate)	Notes
Children (under 12)	85-90 cm	Consider lighter weight options. Focus on proper grip and basic forms.
Teenagers (13-17)	95-100 cm	Gradual increase in weight and length as strength and skill develop.
Adults (General Use)	101.5 cm	Standard size for general practice. Experiment with different materials and weights to find what feels best.
Adults (Strength Training)	101.5 cm + (Heavier Weight)	Focus on controlled movements and proper form to avoid injury.

Beginners should prioritize a lighter weight bokuto that allows them to focus on proper technique and form. A heavier bokuto can be introduced later as strength and skill increase. It is better to choose a cheaper bokuto at first as the chances of the bokuto breaking increase due to beginner mistakes.
Also be careful not to hit the bokuto against a wall or the floor.

5. Purchasing Considerations and Maintenance

• Reputable Suppliers: Purchase your kendo training sword from a reputable supplier specializing in martial arts equipment. This ensures quality and safety standards. Look for suppliers with good return policies.
• Inspection: Before use, carefully inspect your bokuto for any cracks, splinters, or other damage. Discard damaged bokuto immediately.
• Storage: Store your bokuto in a dry, cool place away from direct sunlight to prevent warping or cracking.
• Maintenance: Periodically clean your wooden bokuto with a damp cloth and apply a light coat of mineral oil to prevent drying. Synthetic bokuto can be cleaned with soap and water.

6. Types of Bokuto

• Standard Bokuto (Daito): The most common type, designed to represent a katana.
• Wakizashi Bokuto: Shorter than the daito, representing a wakizashi (secondary sword). Used for specific kata.
• Suburito: Heavier and longer than the standard bokuto, used for strength training (suburi). These require practice to prevent muscle injury, so it is recommended to seek advice from a kendo instructor.

Alright, that about covers it! Choosing the right kendo training sword can seem daunting at first, but hopefully, this guide has given you a clearer picture of what to look for. Now get out there, practice your swings, and enjoy the journey of Kendo!
