POCKET CORK SCREW No. 21
Erie Specialty Company, Erie, Pa., are putting on the market the pocket cork screw herewith shown. The points of excellence enumerated by the manufacturers include the following: That the screws are made of steel and finely tempered, highly polished and nickeled: that they will draw any cork, and that they are strong and durable. In Fig. 2 the cork screw is shown in the shape for carrying in the pocket, being compact and taking but little room. The goods are attractive in appearance and are made as either right or left hand, as desired.

Interestingly, of the two Walker peg and worms in our collection, one is right hand and one is left hand…
