How do you "Disable Device" ?

[RObiN-HoOD]

There is a trap that the rogue have found out about it. He uses the Disable Device and he passes the DC. Does he just disable the trap like that or does he requires some tools for doing so?

For example, perhaps sealing wax to seal a hole, or a crowbar to screw a mechanical trap?

Is it by the rule to require that kind of tools?
