The Sacking Needle has a long history appearing on knives in the early 1900s. This tool was used to closeup burlap sacks or similar with a heavy thread of the same material or other. This would be used primary in farming and the rest of the agriculture industry.
This tool was later adapted for the marine industry as a Marlinspike with sewing eye.
