Origin and Etymology of novaculite

Latin novāculum "razor" (from novā- —going back to earlier *ksneu̯ā- "scrape smooth, sharpen"— + -culum, instrumental suffix, going back to *-tlom) + 1-ite; *ksneu̯ā-, probably derivative of an Indo-European adjective *ksneu̯͟-o- "scraped smooth," from a verbal base *ksneu̯- "scrape (until sharp or smooth)" (whence, with ablaut variation, Sanskrit kṣṇáuti "(s/he) whets, sharpens," kṣṇutáḥ "sharpened," kṣṇótram "whetstone," Avestan hu-xšnutō "well-sharpened"), iterative derivative of *kseu̯-, whence Greek xýō, xeîn "to shave, smooth"
