tang dimesions? in Fit and Finish Posted June 18, 2005 As a general rule, a hidden tang should be at least 2/3 the length of the handle. I make my hidden tangs as wide as I can get away with, slightly tapered in all dimensions. When in doubt, overbuild... If the tang does not pass completely through the length of the handle, it is a really good idea to pin it.... never just trust the epoxy to hold it together. I've never burned in a tang, never trusted the method enough not to damage the handle material. I expect the heat could have a detrimental effect on most of the materials I use.
