Whalebone snow knife reproduction. This is a piece that I made few years ago for The Rooms. Its based on Thule Inuit snow knives from Labrador. I can't recall the exact dimensions, but I think it was around 16-18 inches long. Its flat on one face and slightly convex on the other - kind of like a plane's wing in cross-section.
This is one of the knives in the collection at The Rooms that I used as a reference piece.
