I ask for sufficient detail in combat — where do you stand, where do you face, what is your attack like, where is it aimed, what do you do after — precisely because it makes it more interesting and it's a potentially dangerous circumstance. So I do that with other dangerous circumstances. «I bend back the needle» is just an example, and not an exhaustive list of the kind of detail you need. I'd accept other statements of action as long as I know what you're doing, not just your goal. Honestly, you can choose a fairly poor approach and roll well and succeed, because the dice tell us how it worked out. So maybe you say «I break the needle» or «I bend the needle» or «I smash it with my dagger pommel» and make your Traps roll and it all works out.
