That is upholstery needle... for sure, I have one and it came with a few others for heavy duty fabric on a card in a packet.... I think you might be able to find it or them at Joanns in the area where the upholstery fabrics and notions are for that fabric... or possibly at an upholstery shop where they sell the fabrics just for upholstery... call around first but do say it comes on a card a group w/ the strong needles...
