I was doing a search for custom handmade lighters, preferably running on Zippo fluid, and I found this... He also does engraving with various fonts for a fee. Deep CNC engraving.
Looks like the solid brass lighter will cost $95 as opposed to the aluminum version at $75. Still a helluva value for a custom torch. As for weight the all aluminum ones are around 75 grams. The ones with the brass bottom that he has on ebay are around 95. The solid brass models are well over 100. For comparison, a Zippo lighter weighs 67 grams full.
PS... My solid brass lighter will be finished soon. Will post pics.
