In Hindu mythology,different weapons have been received from Lord Shiva.But I was wondering if there is any mention of anyone receiving Lord Shiva's Trishul as a boon.
None in past.Shiva still holds it.The matter of fact is that what people think of as infinite number of trishuls,brahmastra and other weapons can exist if boon is granted is false.What i mean is that there is only one unique trishul of shiva like sudarshan of vishnu these are unique weapons unlike brahmastra aur other weapons which can be created using chanting of mantras when invoked by the observer with sharp mind.Remember anyone can take shivas trishul but with very hard penance and with the order of shiva himself.Read the stories of pinaka dhamush which was that of shiva and later passed to the ancesters of sitas parent which was broken by ram in the swayambara so it was not that a new pinaka was created instead the same was passed by shiva.

Nobody had received Vijay trishul from Shiva. Nobody was able to hold it except shakti. It represents three gunas or qualities, controlled by lord Shiva.
