Efectivamente, son unas anclas estupendas. Yo estoy encantado con ella.

En la actualidad, como ya ha comentado alguien, todas las anclas ROCNA se fabrican en China. Copio de su página web:

Since taking over Rocna anchor production, these quality control processes and procedures developed at our head office in Vancouver, BC, Canada have been incorporated into anchor manufacturing through our wholly owned subsidiary in China. Material traceability is one of the key elements of this program. Through tracking numbers embossed on every anchor, it is possible to trace the steel used in the anchor back to the original material certificates documenting its composition and mechanical properties.
There are multiple inspection points during the production of every anchor, both at the sub-assembly level and at final assembly. Our inspectors take quality very seriously, and maintain extensive documentation on each and every production run.

Según esto, debería ser posible averiguar los controles de calidad por los que pasó el ancla, de ser original, claro.

Serte con la devolución.
