A Complete Guide to Choosing Practice Swords: Wooden Swords, Replica Swords, and Real Swords—Comparing by Purpose and School

Types of Training Swords—From Wooden to Real Blades

Training swords used in kendo, iaido, sword-drawing arts, and various classical martial arts are classified into four main types:

1. Bokken (木刀): Wooden training swords
2. Replica swords (模造刀): Metal swords that cannot cut—non-functional replicas
3. Iaito (居合刀): Practice swords manufactured specifically for iaido training with dull or no sharp edge
4. Shinken (真剣): Genuine Japanese swords, used only by advanced practitioners and dan-ranked students

This guide explains which type to choose based on purpose, martial arts school, and skill level.

Bokken—The Most Fundamental Training Tool

Types of Bokken

Ebony bokken (黒檀木刀): The highest-quality wooden sword. Hard, heavy, and highly durable. For advanced practitioners. Priced around ¥30,000–¥100,000.

Kashiwood bokken (樫木刀): The standard material for most bokken. Available in white oak and red oak varieties. Most commonly used for kendo and sword arts training. Priced ¥3,000–¥20,000.

Cherry bokken (桜木刀): Made from cherry wood. Soft with good flexibility. Recommended for beginners.

Polypropylene bokken (plastic sword): A modern material option. Used for outdoor training and children's practice. Highly weather-resistant.

Bokken Specifications by School

Different martial arts styles require different bokken specifications:

• All Japan Kendo Association (AJKA) Standard: 101 cm (long sword) / 91 cm (short sword)
• AJKA Iaido Standard: Approximately 101 cm, total weight around 400–450g
• Classical Schools: Varies by school. Consultation with your instructor is essential

Replica Swords—For Display and Demonstration

Replica swords are metal products that "resemble Japanese swords in appearance but lack practical cutting ability." While the blade is made of stainless steel or similar metal, it is either not sharpened or has a dull edge.

Primary Uses for Replica Swords

• Cosplay, demonstrations, and film props
• Display as collectibles or room decoration
• Stage and video production use

Legal Considerations

Even replica swords with a blade length of 15 cm or more can constitute a violation of Japan's Swords and Firearms Control Law if carried without "legitimate reason." Purchase and possession are not prohibited, but carrying them in public should generally be avoided.

Price Range

• Mass-market items (Chinese-made, etc.): ¥3,000–¥10,000
• High-quality Japanese-made swords: ¥20,000–¥100,000
• Fine art swords and famous sword replicas: ¥50,000 and up

Iaito—The Primary Tool for Iaido Practice

Iaito are metal swords manufactured specifically for iaido and sword-drawing art practice. While they resemble Japanese swords in appearance and weight, they are intentionally designed without—or with severely limited—practical cutting ability for safety.

Types of Iaito

Fine Art Iaito (Non-cutting): Completely unsharpened, designed solely for practice. High safety. Suitable for beginners through intermediate practitioners.

Semi-sharp Iaito: Lightly sharpened. Capable of cutting straw bundles in practice. For intermediate practitioners.

Test-cutting Iaito: Fully sharpened, capable of cutting straw bundles and tatami mats. For advanced, dan-ranked practitioners.

Iaito Materials and Price

Selection by School

All Japan Iaido Association Standard: Blade length 73–76 cm. Standard weight 800–1,000g.

Classical Iaido Schools (Shindo Munen-ryu, Musou Jikiden Eishin-ryu, etc.): Consult your instructor. Specifications for length, weight, and curve may differ by school.

Shinken—The Advanced Practitioner's Path

Real swords (genuine Japanese swords) are generally used only by dan-ranked and licensed practitioners.

When Real Sword Use Is Permitted

• Practitioners who have achieved a certain rank (varies by school)
• Special occasions such as shrine dedications or demonstrations
• Individual practice in safe environments for form work

Important Considerations for Purchasing and Using Real Swords

1. Instructor Approval: Never use a real sword without your instructor's permission. Always defer to your teacher's judgment.
2. Registration Certificate: Possession of a genuine Japanese sword requires a registration certificate.
3. Safe Training Environment: Real sword practice requires adequate space, appropriate flooring, and proper safety measures.
4. Insurance: Accidents involving real swords are often not covered by standard injury insurance policies.

Choosing Your First Real Sword

Advice for advanced practitioners purchasing their first shinken:

• Unsigned swords from the late Edo period (新々刀): ¥500,000–¥1,000,000. Well-conditioned pieces are suitable for training use.
• Modern swords (Showa through Reiwa era works): ¥400,000–¥2,000,000. New swords offer clear durability and condition records.
• With authentication certificate: Minimum NBTHK Registered Sword level or higher

Conclusion—The Right Sword Elevates Your Training

The saying "tools build the practitioner" applies equally to kendo and iaido. Selecting the correct sword for your rank, purpose, and school's requirements enhances both the quality of your training and your safety.

Beginners should always consult their instructors and choose swords that meet their school's specifications. This is the essential first step toward proper martial arts practice.
