And that brings up another point ....
Use an etching tool or Dremel .... and mark your stuff Thumbs Up (especially the high $$ stuff)
Either use a mark that you can identify (what it looks like & where it's located) ... or your name, or initials (phone # ??). All that will help the "finder" be able to get it back to the "owner". Hands Clapping
Myself, I'd try to locate the owner .... with a serious effort for about a month .... and if no luck, I'd consider it "mine". Not knowing what the original "owner" was fishing for, would leave me in a quandary as to whether to use the marked spots or not. I see the dilemma ... do you consider the "spots" as sacred, found & marked by the previous owner :confused: ... or do you consider the "spots" the same as $$, found in a wallet with no ID :confused:
