Ishi Sashi, stone padlocks

Ishi Sashi, or stone padlocks, were originally the locks used on Okinawan doors. When removed they also make excellent tools for developing grip, shoulder, and wrist strength necessary for martial arts. Tools similar are found in many other cultures, the most popular being the Russian kettlebell. Ishi Sashi are traditionally used in pairs and in a wide variety of exercises. This ishi sashi are made of concrete with anchored wooden handles. They weigh 10lbs each. As with any small molded concrete item small cracks and chips are common and perfectly safe. Please contact me if you have any questions. The ishi sashi is part of a whole line Hojo Undo equipment I make including standard and olympic weight sized chi ishi handles, nigiri game (gripping jars), makiwara (striking posts), kongoken (weighted oval and literally the greatest thing ever), and Wing Chun Dummies. I can also take custom orders if you have something specific in mind. There are virtually no suppliers of these items so I'm happy to do my part.
