Arch wire arrives straight; everything clinical about it happens in the bends. Four plier patterns cover almost all of that work, and knowing which does what turns a drawer of look-alike tools into a deliberate kit.
1. Bird beak: the loop-maker
One conical beak, one pyramidal — round bends form around the cone, sharp bends form against the pyramid. The 13 cm bird beak is the first bending plier any kit should own; if the bench holds only one, this is it.
2. Adams: the clasp specialist
Rectangular beaks with precise parallel faces, built for the sharp, accurate bends of Adams clasps and removable appliance work. The 13 cm Adams pliers grip flat where a bird beak would roll the wire.
3. Three-jaw: the contourer
Two jaws oppose one, so the wire curves smoothly the moment you squeeze — sweeping arch adjustments and clasp contouring without kink points. See the 13 cm three-jaw contouring pliers.
4. Tweed: repeatable loops
The Tweed loop-former with three-step round beak makes loops in three fixed diameters — same loop, every time, which matters the tenth time you form one. For placement and finishing around these bends, the Howe pattern (straight Howe utility pliers) does the holding.
5. Building the kit
Bird beak first, then the pattern your appliance mix demands. Every plier above is box-joint construction — why that matters for jaw alignment under load is its own article — and hard wire needs its own cutters, never bending-plier jaws (cutters guide).
