Lobster Man,
Your knife dates from the early 60's...Had an Identical one when I was much younger.
The handle, though plastic, was originally colored alternating shades of caramel and dark brown, and was meant to look like stag horn (antler). As I recall, for an inexpensive kid's knife, you could put a good edge on it ... and yes, I tried to stick it in a tree from a distance a time or two!
