Brass blowpipe Bunknal

The Brass Blowpipe, known in the trade as a bunknal, is a traditional goldsmith tool for directing a small, controlled flame onto the work while soldering. By blowing air through the pipe into a lamp or torch flame, the jeweller can focus heat precisely on a joint without overheating the rest of the piece. Made of brass for durability and a comfortable feel. Still widely used by Indian goldsmiths for chain, ring and repair soldering. Supplied by Dinanath & Sons, Delhi goldsmith tools supplier since 1960.
