Dunno about you, but “placoid” isn’t a term I tend to use in daily conversation — or even one I had read or heard before today.
While the various metals combined in the forming of Damascus steel are layered like lasagna, what brings the look to life is a treatment called acid etching, which provokes different reactions from the different metals and reveals the beguiling patterns that give this steel such a distinctive style.
But upon further review/investigation, I am both quite intrigued by the word and find it incredibly fitting as the moniker for an impressive-looking new knife, with one of its blade options in particular.
So hey, let’s get to know the Civivi Placoid.

Tipping the scales
According to Collins dictionary, placoid is a zoological word with Greek origins meaning “of or having scales that are periodically shed and replaced, consisting of a dentin base and an enamel-covered surface, as in cartilaginous fishes.”
In something closer to plain English, it basically refers to the tooth-like replaceable scales you find on the skin of sharks and some other fish.
