to make ds1 a personalised set of rune stones as he's into norse mythology and stuff like that (he already has a leather necklace with stone pendant with his rune initial on it).
So as I am going to make him a set of stones (and put them in obligatory ye-olde-leathery pouch) . I could just buy a set, obviously, but I'm thinking this will be more personal and I get to buy an engraving pen which I've always secretly hankered after but never had any use for :D
What else could I use it for? Just to help justify the purchase? I know you can engrave stone, wood, glass and plastic with it, but I need some good ideas. Any thoughts appreciated!
