How many racquets have you strung and had big problems from using an awl? I have never had such an issue.An awl for stringing in modern thin walled racquets is not a good idea
It is much better to use a hook to get 2 strings through a double hole.
Something like this
The hook can be very useful for badminton shared holes or for other similar situations, but it will not magically make a hole that is barely wide enough to take one string suddenly take two strings. The hook can help with angles, but it cannot help with insufficient width.
