CE ÎNSEAMNĂ TWEEZERS ÎN ENGLEZĂ?
Pensetă
Pensetele sunt unelte folosite pentru ridicarea obiectelor prea mici pentru a fi manipulate cu mâinile omului. Acestea sunt probabil derivate din clești, clești sau clești de tip foarfece folosite pentru a apuca sau a ține obiecte fierbinți de la începutul istoriei înregistrate. Într-un context științific sau medical, acestea sunt denumite în mod normal forceps. Pensetele utilizează două pârghii de clasa a treia conectate la un capăt fix, cu clești la celelalte. Pensulele pot fi folosite pentru sarcini cum ar fi smulgerea părului de pe față sau de sprâncene și ori de câte ori obiectele mici trebuie manipulate, incluzând, de exemplu, piese electronice mici, în special de suprafață, precum și piese mecanice mici pentru modele și mecanisme de precizie. Colectorii de timbre folosesc pensetă pentru a manipula timbrele poștale, care, deși sunt suficient de mari pentru a le ridica cu mâna, ar putea fi deteriorate prin manipulare; fălcile cleștelor de timbru sunt netede. Un exemplu de utilizare specializată este alegerea fulgilor de aur în panningul de aur. De asemenea, a folosit în bucătării pentru a îndepărta oasele din filele de pește într-un proces cunoscut sub numele de dezosarea de pin.

Eyebrows are really important because they structure the face. In school it was funny because I was always the one walking around with tweezers plucking my girlfriends' eyebrows. I was really good; eyebrow tweezing runs in my family - my mother used to do mine, and I picked it up.
