This is a detail showing the irregular edges produced by the revolutions of the mani against the shell. They are not finished the way they would be if they were manufactured as disc beads.

It is difficult to describe but there is usually a small segment of bamboo or wood inserted in the bottom of the cylinder of the Mani that wears a groove into the shell at the bearing point eventually producing a disc bead as it is worn out and then replaced by a new piece of shell.

Do you get my point? Do I get my point???
