Etymology
The name Chirijiraden is actually the shortened version of its actual name, Chiriji Raden Kazari Tsurugi (塵地螺鈿飾剣).

Chiriji was a type of lacquering method used in the Heian period in Japan, which mixed precious metal dust with lacquer and created a dusty grainy like texture when dried, allowing the work to have the illusion of actually made of precious metal (which was very scarce in that time).

Raden is Japanese for mother-of-pearl, which is part of the process that makes pearls in shellfish, and is widely used for decorating various works, from accessories and weapons to jewelry, furniture and architecture. Kazari is a verb that donates " made of-".

With the mention of Tsurugi (Japanese for sword), and the immense skill it takes to utilize into the weapon, the words clearly state that all methods mentioned are used into this sword.
