Among the tools in the upcoming Wrenching News Auction. It's 7.5" long. The only marks are "42" "S" and a "S+" logo.
Pouch is marked: "J. Nuesch Sattler - Heerbrugg". I presume they were the maker of the pouch.

It isn't for fire hydrants, but it could be for hose valves. They have square nuts, and they are in two sizes of outlet 1-1/2" & 2-1/2". I think a compact safety tool. The point could be for breaking glass. What is on the bottom, it doesn't look like a flat blade. Could it be for an access panel?

That is probably it or close to it. Here's pics of the end:
