So in the scene I'm writing right now, one character has just ordered the other to remove his own tongue. For various reasons, the character is forced to comply with this as best he can. He's being put on the spot and has no time to do anything but try to carry out the order; the only tools he has available are his own sword, and presumably teeth/hands/etc.
The situation is meant to have a certain twisted fairytale feel to it, so total realism isn't 100% necessary, but how much damage would someone actually be able to do to the tongue in a situation like this? Would he actually be able to get part of it off? How much time/work would this entail?
Searched through several little_details tags and Googled various combinations of 'tongue cut out', 'tongue removed', 'tongue self-removal', 'auto-glossectomy', etc but didn't really turn up anything relevant.
