Here is a nice addition for any Schrade knife collector. This is a Schrade Walden Model 735 Mariner knife with the marlin spike. In overall very nice condition for the age. These were made from the late 1940's to the early 1970's. This one does not have the lock mechanism on the spike, which indicates that it is one of the earlier models from what I have read. Very functional piece that would be great for boat carry or to put in the display case. Don't see these very often so act fast!
