Hi,
I've bought some cheap torch lighters from the German Globetrotter Outdoor shop.
Our Scouts use them and my personal copy got used extensively over the past 2 months.
They cost me $5/piece and it is the best $5/piece that I invested in lighters for ages.
It's not waterproof but if you put it in a survival kit just put it in a small ziplock bag or stuff it in a condom.
The advantages of the lighter are:
1. its pinpoint torchflame it produces which it's really hot, I even Silver soldered with it, lighting Mayawood takes only a few seconds.
2. it has a very large fuel reservoir that is clearly visible so you know how much fuel you still have left.
3. the cheap price, if you loose one or it breaks it doesn't hurt your pocket.
I think they are a knock-off of some torch lighter that was first produced by a company that made soldering products, but I never saw the originals.
Although this lighter isn't waterproof and won't survive a 30 foot drop onto concrete it hasn't failed on me yet and even better I could get 8 for the price of one of the lighters mentioned in the posts before this post.
Best Scouting wishes from Holland,
Bagheera
