Offered here is a souvenir letter opener made from a small branch or sapling. Grip portion is untouched with original bark. The end of the grip is cut on a 45-degree angle and has a Stanhope lens embedded. The lens features an illustration of the “Battle above the clouds”. The “blade” portion is carved down smooth and thin with “Lookout Mt. Tenn” cut in on one side.

Stanhopes or Stanho-scopes are optical devices that enable the viewing of microphotographs. A Stanhope lens is a simple, one-piece microscope invented by Charles, the third Earl of Stanhope. It is a cylinder of glass with each end curved outwards, one being more convex than the other. Because its construction is simple and economical, it was popular in the 19th century. In 1857, René Dagron modified the lens by keeping one curved end to refract light while sectioning the other end flat and locating it at the focal plane of the curved side. Dagron used the modified Stanhope lens to mount microscopic pictures.   [jet] [ph:L]
