Hebrew

taˁar - knife, razor (HALOT 1770)

PC
*yaˁr-/*taˁr- - knife, razor (BDB 788‒789, Aistleitner 1963: 242, HALOT 1770, Kogan 2015: 313)
origin of PC *yaˁr-/*taˁr- ‘knife, razor’ remains uncertain, although the traditional derivation from *ˁrw ‘to be naked,’ accepted in BDB 788‒789 and Aistleitner 1963:242, but rejected as “clearly not relevant” in HALOT 1770, is still attractive, especially if the term denoted specifically a shaving razor (Kogan 2015: 313)
