Shakuhachi Bindings, Care, and Cracks

Bindings for Crack Repair and Prevention

When an unbound bamboo shakuhachi develops cracks, bindings are applied to close and repair them. However, when applied proactively, bindings greatly help to prevent cracks in the first place.

The Enduring Strength of Bound Shakuhachi

I expertly bind all my shakuhachi, a tradition rooted in the practices of the revered Komuso monks and earlier. My bindings are so effective, cracks requiring repair hardly ever occur. This is why I confidently offer lifetime free crack repairs. Beyond their utility, bindings are true badges of honor, signifying deep dedication and respect. Of course, you are free to remove them if you wish (removal voids free repairs and incurs a rebinding fee if returned). Additionally, fussy humidified storage is not necessary. In this way, you get virtually worry-free bamboo in your hands.

My Commitment to Expert Binding

The effectiveness of bindings hinges on expertise. From the style of binding (topical or inlaid), the choice of cord, and how they are sealed — all are paramount. This is why I’ve invested an enormous amount of time and effort into perfecting the art of binding. For example, I’ve stress-tested hundreds of bindings on scrap bamboo pieces placed in ovens. This rigorous testing is A big reason why I’m confident enough in my bindings to offer lifetime free crack repairs, should any cracks impair the function of your fully bound shakuhachi.

There are two main types of bindings: topical and inlaid. Inlaid bindings involve cutting a recessed channel into the bamboo into which bindings and a veneer are placed. While they offer a low-profile aesthetic, ironically, cutting into the bamboo significantly increases the likelihood of further cracking. This is why I exclusively use topical bindings, which provide superior crack prevention without compromising the integrity of the bamboo.

If you want a virtually carefree and worry-free bamboo shakuhachi, I strongly encourage you to embrace bindings, just as the wise Komuso did.

How to Bind Bamboo Shakuhachi

I made this videos for the curious, but also as a service to the community for those that wish or need to try their hand at binding cracks in bamboo shakuhachi. These methods can also be used on other types of bamboo flutes, though with thinner bamboo exercise caution with the clamping pliers.

Materials and tools used:

• Bonded twill nylon or poly cordage; 0.5mm dia. minimum (tex 210); ~3 yards per binding.
• Razor knife.
• Locking Forceps (teeth wrapped with electrical tape).
• Locking vise pliers/grips (teeth coated in hot glue or heat-shrink rubber tubing).
• Glue or lacquer to finish/seal this type of cordage (epoxy is best).

Care for Unbound Shakuhachi: How to Prevent Cracks (in lieu of bindings)

If your shakuhachi is not bound, it’s best to avoid extremes in temperature and humidity whenever possible. To significantly reduce the risk of cracks, use humidified storage when the humidity drops below 50%. Below is one of the simplest methods for humidified storage:

As shown in the image below, a damp piece of material is placed between two ‘twists’ at the top of a plastic storage bag and secured with a rubber band. Be sure to regularly check the damp material for mold and replace it as necessary, or clean it with distilled white vinegar. You can use a small sponge, paper towel, or a piece of fabric.

How to Prevent Odors and Mold

After playing, always swab the bore with a tsuyutoshi—a piece of fabric with a pull-string tied to one corner. To make one, cut fabric to a size that will fit down the bore (approximately 1 sq. ft. or 30 cm sq.) and tie a string longer than your shakuhachi to one corner. When pulling it through, protect the sharp blowing edge with the soft part of your thumb. A 50/50 mix of distilled white vinegar and water can also be used to clean the inside.

As you can see, caring for your bamboo shakuhachi, no matter what, is quite simple. Enjoy,
