Turn Your Lighter Into A Blowtorch
You can adjust your lighter to get a bigger flame, and if you're clever—and reckless—you can also mod your Bic to get it even bigger. All those DIY tricks may be cool, but none are as awesome (while still being safe) as pairing your lighter with the Soto Pocket Torch.
Accepting any rectangular lighter (not Bic), the Pocket Torch will concentrate all that butane into a little jet that burns up to 2,300°F.
Besides the cool factor, you can use the Pocket Torch to cut and cauterize rope, start a campfire faster, solder small objects in a pinch, and melt things faster. But let's face it, the cool factor is way more important.
