खरुम्बः पाण्डुरोहितः सिन्दुवारपुष्पवर्णो वा तीक्ष्णधातुः ॥ कZ_०२.१२.१५ ॥
kharumbaḥ pāṇḍurohitaḥ sinduvārapuṣpavarṇo vā tīkṣṇadhātuḥ
‘Tīkṣṇa’ metal/ore (sharp/strong metal—typically iron/steel class) is ‘kharumba’; it is pale-reddish, or of the color of sinduvāra flowers.
Because strong iron/steel underpins weapons, tools, and infrastructure; identifying and classifying it supports state security and productive capacity.
