Evidence & Historical Context
Editorially reviewedDocumented identification
A crescent-bladed Lambayeque-Sican ceremonial metal knife, or tumi, represented by documented examples dated to about the ninth through eleventh centuries.
Historical meaning
Elaborate tumis participated in ritual display, elite status, political or ceremonial power and funerary deposition.
Scholarly interpretation
The object belongs to a wider ritual setting that can include sacrifice, so its meaning cannot be reduced to the blade form or to one benign modern use.
Modern associations
Authority, ceremony, identity and mortality are source-led discovery associations; healing and luck are not supported meanings for this entry.
Research warning
Do not recast the tumi as a generic healing implement, protective charm or universal good-luck knife.
Provenance: Contemporary cut-safe study based on documented Lambayeque-Sican tumis in the Metropolitan Museum, preserving the crescent blade and ceremonial object character without copying one artefact exactly.
Context note: The tumi's documented context includes ritual power, sacrifice, and elite burial; avoid reducing it to a generic healing or good-luck emblem.
