My strings seem slightly too long. When the shamisen is in tune, there is so much string wrapped around the itomaki that I’m running out of space between the hole and the wall of the tenjin box (I think that’s the name??).
Is it safe to trim an inch or so off the strings? The ends of the strings seem to dipped in metal or something (they are silver and stiff). Is this just to make it easier to insert into the hole in the itomaki? Or are the require to keep the string from fraying or something?
