Looking through my footlocker of knives I saw one my Father had given me. He was a Port Captain for Moore-McCormic Steam Ship Lines in NYC in the 50's and 60's before he went back to see. The knife is a Schrade and marked in three lines: "Schrade", then "Walden", then "N.Y. USA". Typical rope knife blade, tip sharpened back, very strong spring, carbon steel blade that takes a very good edge, and what looks like walnut scales with four pins and a lanyard hole. The butt is cut of square and inserted into the left scale is an one inch by 1/2-inch white plastic rectangle with red, white and blue lines. In the top red stripe it says "Rope", in center white strip in blue letters it says "Columbian" and in the bottom blue stripe it says in white letters "Twine". There is also a circle of rope on the rectangle. I am pretty sure it was given to my Father by the Columbian Rope and Twine Company, but wonder what era it might be from. Thanks.
