Great care is necessary when studying weapons in martial arts. In the beginning, there are specific forms or drills one must go through in order to understand the characteristics of the weapon that is connected to the ryuha¹, or style of martial system, one is training in. One of the challenging points to ensure correct study is obtaining a training weapon proportional to your body type. For this post, we will look at how the characteristics of weapons (i.e. measurements, material, etc.) are preserved by traditional schools and the hurdles that come with this, the ups & downs of dealing with manufactures that follow the “one size fits all” model, and how one should go about to training with weapons that match us properly.
IMPORTANCE IN DETAILS VS MARTIAL SYSTEMS
A good martial arts school will ensure that new students obtain a training weapon suitable for them, whether they are buying it or not. For Japanese traditional martial systems this is commonplace. For example, there are numerous types of systems for kenjutsu² (sword techniques), each with their own unique philosophies. Some may specialize a slightly shorter blade length that requires ashisabaki³ (evasive movements with the feet), or a much longer blade where maai⁴ (distance) and chōshi⁵ (timing) are key components. Others may utilize a nitōryū⁶ (2-sword style) system, where two swords that are wielded in each hand are a different size from each other. At any rate, when wielding a sword that does not fit your school’s criteria, unforeseen adjustments will be made, which will prevent a new student from grasping the principles of the particular kenjutsu being studied.
Example of training kusari fundo I’ve made over the years. Each can have a variation in length, weight, size of the weighted ends, etc.
During my years as an assistant instructor at my previous dojo, I was adamant regarding using training weapons that were proportional with those who attended my class. In one case, the monthly theme was a weighted chain called kusari fundo⁷. We used rope versions for safe training. Since I was already making these rope versions for my own training, I did so for those who attended my class to ensure they learned correctly. I had to measure each student’s arm length so to have their rope kusari fundo tailor-made to them.
There is an interesting story⁸ that deals with the weighted chain. A man by the name of Charles Gruzanski, a military officer stationed in Japan during the 1950s, was accepted as a student in Masaki ryu Manrikigusari jutsu⁹ under the 10th successor at the time, Nawa Fumio. One of the challenges that his teacher had to deal with was finding an appropriate chain size for Charles, as he was a tall man with large hands. The weighted chains that Fumio had just were too short, which would’ve made studying the techniques difficult to comprehend. Through some searching, he finally tracked down a chain from a different style that was large enough for Charles to use. This story is an important reminder that appropriateness in weapon size is necessary in the beginning of one’s training.
DETAILS IN ANCIENT DOCUMENTATION
There can be a fascination regarding information in ancient documentations, such as scrolls and manuals. Those that have descriptions of weapon dimensions, for example, are important details critical to the identity of a martial system. However, one must take caution in following these details too literally. When a training weapon is being prepared based on specific dimensions, it still needs to be adjusted based on the student’s body proportion.

Let’s look at a very common weapon used in Japanese martial arts, which is the rokushaku bo¹⁰, or 6-shaku staff in English. A shaku¹¹ is an old measurement unit used in Japan. This “6-shaku” is a length that serves as a standard, a rough measurement for a staff that should be around or slightly taller than your height. In the past, this length would be appropriate for most Japanese martial artists that were above 5 feet, but it was not unusual for the staff to be made shorter for accommodation purposes. Likewise, those who are much taller than 6 feet (especially in western countries) would need a staff slightly longer. In cases like these, access to having weapons custom made according to a practitioner’s needs is a must.
SHOPPING TIPS FOR THE RIGHT SIZES
Shopping for one’s training weapons can be at times difficult. Going to a common martial arts store in your neighborhood that sells everything at only one size is limiting unless you are at that perfect height where everything fits your body type (around 5″6 & up). When shopping around, especially online, what you should look for from retailers is those that A) provide multiple sizes, B) provide customization services, or C) custom make their weapons.
Stores that offer multiple sizes of a particular training weapon is very convenient. Not only does it make finding one that fits you quickly, but this is also convenient for practitioners of all ages. For example, some stores may offer a wooden daito¹² (a standard sized sword) in 3 sizes: large, medium, and small. This ensures that no matter which size you select, it is proportionally designed, from the blade down to the handle. Those needing a smaller size daitō will not need to substitute with a wooden kodachi, which is naturally designed as a one-handed short sword¹³.
Some retailers may offer a customization service, whether they do it on-site or can have it done by another party. This is good when small adjustments are needed, but don’t necessary need to be redesigned from the ground up. Looking at the rokushaku bō as an example, it may be possible to have one adjusted in length in the case where a shorter one is needed.
Possibly the best option is to shop from a retailer who has training weapons custom made. Not only is it possible to have the dimensions tailored to your liking from the smallest detail, but can go as far as craft it and make it unique just for you. While this can be a great option, it can also be more pricier, as time, cost of materials, and labor goes into custom making training weapons. Quality control for custom made weapons tends to be very high, so if money and time is not an issue, then this is a great route to go.
As a rule, it is important to train with weapons that proportionally match. Finding what matches the practitioner is a task that can be handled by the teacher, as it will ensure little to no errors when purchases are made. However, when this has to be in the hands of a student, the best choice are from retailers that give many options that can fit one’s needs.
2) 剣術. An older name related to fighting techniques with a sword. The modernized system of kendo (剣道) derives from this.

9) 正木流万力鎖術. Manrikigusari is another name for a weighted chain.
10) 六尺棒. Usually translated as 6-foot staff in English, thus most are sold as so. However, in reality 6 shaku does not equal to 6 feet.
11) 1 shaku = 11.93 inches.
11) 小太刀. A big difference between a daitō and a kodachi is that the handle of a daitō is long enough for 2 hands to grip, while a kodachi’s handle is long enough for only one hand. Size difference in handle makes it difficult, if not impossible, to practice kenjutsu that requires a normal sword, such as a daitō.
Please note that I didn’t list any retail websites that would fit as good sources for purchasing training weapons, especially the ones that I personally use. For anyone interested please let me know by email at email@example.com or firstname.lastname@example.org.
