OK, some of y'all are on the right track with the pattern..
Perhaps I should give up a hint here:
Remember now, Dick Proenneke was in the Alaska wilderness and shooting his now famous film starting in the spring of 1968. He made pretty damn near everything including the handles for many of his hand tools right down to the wooden hinges and latches for his hand made log cabin door.. Put yourself in his shoes at that time and keep in mind that his trusty and well used pocket knife must have been produced prior to his trip into Alaska... And thats my hint thus far for everyone.
