The Autumn Spirit of SiL Manufactory® Inspired by crimson leaves, we revisit the biblical tale of the Brazen Serpent—forged by Moses to deliver the Israelites on their exodus to Canaan. The prototype’s silhouette fuses Indo-Persian weapon archetypes with the clean lines of a traditional Nordic puukko—primarily its Finnish interpretation. The Spring Pusher Lock™ (a SiL® Manufactory innovation) represents this artifact's core mechanical advancement. While it shares the automatic blade retention of traditional liner/frame locks, its operation eliminates spring manipulation. The user simply depresses the pusher adjacent to the pivot axis to initiate closure – no internal components require direct contact. In essence: The CS PROTO is a luxury art folder that embodies SiL's signature design language—crafted from elite materials with flawless execution. A collector’s grail piece.
