How do you give a player a tool from serverstorage?

The ServerStorage Service is for storing items for the server, not for the player. Like, you would put Maps and stuff in it, instead of using the Lighting for that.

--Place the tool in lighting, then insert something like this
game.Players.PlayerAdded:connect(function(Player)

local cloney = script.Parent:clone() -- clones the tool
cloney.Parent = Player.Backpack --puts the clone of the tool into the players backpack

--Alternatively, you could just put
script.Parent:clone().Parent = Player.Backpack
--I just prefer making the clone a variable. Either way doesn't matter.

end)

 --Connection line is what the player does in order to get the tool. I just did 'PlayerAdded' cause wasn't sure what you needed it for.
