This is the ultimate plier for all sizes of aluminum and almost all sizes of all other metals. (For tiny tight weaves you still need a chain nose plier.) No teeth, light spring, adjustable lap joint, ergonomic cushy longer handles, slight bevel edge to jaw to prevent damage to rings. These pliers can significantly reduces hand strain and makes weaving for hours easy and pleasant.
