there is no reason that "you have to cut a string." most of the rituals described in the thread are to achieve a certain "look" (e.g., "three winds") of the string on the post.
i used to cut them. i was taught to do that by (at that time) more experienced players. when i'd ask "why?" they needed to be cut, the usual response was "so that there won't be any 'slippage' of the string on the post...and it looks better!" however, IME: although some strings, on some posts might "slip" a little bit at first = they all stop slipping as the string breaks in! i haven't discerned a bit of difference between cut and non-cut strings re: "slippage" after the string breaks in to a reliable tuning (maybe a few hours?).
also: there are some great advantages for
not cutting a string!
- easier to re-use those strings on another ax --- especially if you're string/tone chasing.
- more wraps (
above the post-nut string path!) helps to keep the string low (for the break angle purposes) on certain headstocks (e.g., FSOs).
- can eliminate the need for string trees and retainers on certain axes/headstocks.
-
don't need tools to change a string!
- 'catastrophic' failure of a string is most likely to occur with a cut string! (e.g., the 'unwinding' failure).
- there might be others...
and it has been discussed before on TB --- here's a couple:
Do you guys cut your strings or use them whole???

my point: it's a ritual with no real 'science' behind it. folks "cut" based mostly on heresay and tradition, but it's not necessary on most instruments, with most strings, in most situations. most folks do it for "looks."
FWIW: i'd cut any string if i thought it would suit my purpose(s) better.
