Menene Bakin Karfe ...
Bututun bakin ƙarfe mara sumul wani dogon ƙarfe ne mai ramin da babu dinki a kusa da shi. Kauri kauri na kayan, haka yake da rahusa da amfani. Mafi ƙanƙantar kauri na bango, haka farashin sarrafawa zai ƙaru sosai.
Tsarin wannan samfurin yana ƙayyade iyakantaccen aikinsa. Gabaɗaya, bututun ƙarfe marasa sumul suna da ƙarancin daidaito: kauri mara daidaituwa na bango, ƙarancin haske na saman ciki da na waje na bututun, tsadar girma, da kuma tabo baƙi a saman ciki da na waje waɗanda ke da wahalar cirewa; dole ne a sarrafa gano shi da siffanta shi ba tare da intanet ba. Saboda haka, yana nuna fifikonsa dangane da matsin lamba mai yawa, ƙarfi mai yawa, da kayan gini na injiniya.
