A fancy OPMT. Titanium. Beautifully finished and packaged. The screwdriver tip is reminiscent of the Victorinox combo tool, but not nearly as functional due to the Halifax’s thickness. Note the SS “cap grabber” on the bottle opener -it works very well.
Looks fancy, does the opening do anything? Most probably would have put a hex opener hole there.
The opening doesn’t do anything.
Maybe you can use it in oxygen bottles? I seem to recall some OPTs having such a shape used for that.
