I found what I believe to be a knife blade on the beach of Lingan Bay located in Cape Breton Nova Scotia Canada. It was about 6 inches deep under the sand and gavel. It is over 12 inches in length and is sliver where the build up has been removed. A magnet will stick and the metal detector showed sliver and iron on the screen. The rock in the picture was just odd and set my metal detector off for copper and iron, if anyone came across this before.
