From Discworld MUD Wiki
Tiger fangs have the slash stab and iai commands.
I've used them many times. My judge is not yet perfect but it confirms this:
You think that a tiger fang is an extremely good sword which can be used to slash, stab and iai. It is very easy to attack with, incredibly easy to parry with, has a quite high maximum damage and a rather low average damage.
(This tiger fang is enchanted to bright.)
You prepare to slash the sailor with your tiger fang, holding it easily in a practiced grip. [...] You launch a powerful attack. You chop up the sailor's left leg with your tiger fang.
