How do I find a player model so I can identify a tool within it?

I'm making a camera for a Tool and if that Tool is picked up by another player, you can see the Tool still.

I got the ball working, but I don't know how to identify the tool if it's inside the player model.

ball = workspace.Flickball:FindFirstChild("Handle")

num = 1
if ball then
    script.Parent.Selected:connect(function (mouse)
    mouse.Button1Down:connect(function ()
    game.Workspace.CurrentCamera.CameraSubject = ball
    game.Workspace.CurrentCamera.CameraType = "Track"
        if num >= 6 then
        num = 1
        else
        num = num + 1
        end
    end)
    end)
else
    script.Parent.Selected:connect(function (mouse)
    mouse.Button1Down:connect(function ()
    game.Workspace.CurrentCamera.CameraSubject = workspace.
    game.Workspace.CurrentCamera.CameraType = "Track"
        if num >= 6 then
        num = 1
        else
        num = num + 1
        end
    end)
end)
end
script.Parent.Deselected:connect(function ()
game.Workspace.CurrentCamera.CameraSubject = script.Parent.Parent.Parent.Character.Humanoid
game.Workspace.CurrentCamera.CameraType = "Custom"
num = 1
end)

This is what I have

game.Workspace.CurrentCamera.CameraSubject = workspace.

I need to fill this in. It has to be the Player's model in the workspace, but I cannot identify it. I just don't know how.
