'bandsawn' originates from Modern English, specifically the compound 'bandsaw', where 'band' meant 'a long strip' and 'saw' meant 'a cutting tool'.

'bandsaw' arose in the early 19th century after the invention of the band saw; the past-participle/adjectival form 'bandsawn' developed by analogy with the older past participle 'sawn' (from 'saw').

Initially it referred specifically to material cut by a band saw; over time it has remained stable as an adjective or past-participle meaning 'cut with a bandsaw'.
