Description: This listing is for: rare curve sets in 2 different cases - 1) set of 1957 Keuffel and Esser "Copenhagen" ship's curves.2) set of 1800s Kockum Naval Shipyard Curves. (See Images) Similar to "French curves," these "mathematically shaped" curves are used in the same manner as "French curves" by naval architects to draw fair curves when drawing ships' lines. Sometimes called "Copenhagen curves," when used in conjunction with one another to join points laid out on the drafting board, they will permit drawing a fair curve of any shape whatsoever. Dealt a death blow by CAD, like a lot of essential manual drafting instruments, they are no longer made and are unobtainable on the retail market. There was a brief moment in time right after everybody went over to CAD and had no interest in manual instruments when even the finest manual instruments in mint condition could be bought for peanuts. Like vinyl records, the advantages of manual instruments have been rediscovered and are now highly prized by collectors and users alike. K&E: They are made of "Luxylite," K&E's trade name, which is apparently a type of plexiglass plastic material. The early curves were made of boxwood, ebony, and pearwood. In the mid-1800's, some were made of hard rubber. There are 58 pieces ESSER: They are made of wood. There are 27 curve pieces. 85 curves total
