My Philips test pen broke last week, after some ten years of faithful service. Some people swear by them, others hate it. I guess I belong in the former - it's been with me on all my gigs and has been used to do a variety of tasks like opening lids, making holes in bags and covers, ripping open plastic bags, tightening screws, testing for live circuits and digging dirt out of holes.
I'm missing it in my daily work; yesterday, I was troubleshooting a commercial kitchen stove burner and needed to undo a couple of flathead screws. I reached into my tool pouch and there was no test pen. In this case, a Leatherman tool was just too cumbersome for the tight space....
I can't find a replacement test pen here as they don't sell it here. But I've got some guests coming over in a couple of weeks from Singapore and they'll be bringing in fresh supplies.
