They can be decent for killing Wyverns depending on the level of both the wyvern and the griffin. It’s best to dive when you get too low on health to avoid killing the griffin. Diving takes a lot of stamina though so be mindful of how you use it!
Wanna get Wyvern eggs? Use one of these with a whip and you'll get so many eggs you'll end up with so many omelettes that you don't know what to do with them
While diving pull up at the last second above your target and use main left click attack. Does a ton more dmg then just landing on target. Gives a nice speed boost too.
