The mark I place on my knives and jewelry is made up of my initials
"j" and "L" crossed. It is also very close to the astrological
sign for Jupiter. For what it is worth, I have five planets in Sagittarius,
including my ruling planet- so it seems like a good force to draw on.
Of course, Jupiter was equated in Roman times with Donnar,
another Hammer-wielding redhead... which brings me to the fact
that it also looks just a little bit like one Icelandic sigil for Thor...
