How can I make make my prop manipulation device (used with a custom prop) to trigger Damaged event only when a pickaxe is used?

I want to get an event (OnDamaged) when I hit a custom prop, but only when using the pickaxe. Weapons shouldn’t trigger hit. I already found the Weapon Destruction Percentage in the island settings that I can set to 0, but, even if the prop’s PV stay the same, there technically is a damage dealt when hit, so, the event is still triggered.

Is there a way to ignore these weapons?

I haven’t found anything since, does anyone have an idea?
