i've had this little thing for years and never seen another like it an i want to share it with you guys. it has a inique (to me). folding feature. the blade is a little over 1 1/2" and of carbon steel. the blade cover is about 2" and appears to be brass that is plated in a silver mettle. the overall length when closed is 2 1/2" and roughly 4 1/2" when open. there are no markings on the blade but the handle has: Carolina Gas & Oil C0.... Dan H. McCachern (?) on one side and J. W. DeYoung on the other. i feelthat it was carried and likely used by Mr. DeYoung and that it must have been a gift to him from Carolina Gas & Oil Co.
check it out.
