Hand Hammered singing bowls are bowls that are actually formed by beating the bowl with a hammer. This process is a more organic way to make singing bowls, and it is how singing bowls were originally made. Hand Hammered singing bowls have a larger range of tone than cast singing bowls, and they produce a beautiful, intricate sound. Some hand hammered meditation bowls have a wide range of sound in a single bowl. These singing bowls were handmade in Nepal, and each bowl includes a wood striker.
