Autumn is upon the northern parts of the northern hemisphere and we’re stocking up on our cold weather gear. First up, the new hard warmer from Zippo. Unlike the company’s famous lighters, this Zippo produces no flame. Instead, the radiant heat comes from a smoldering of lighter fluid within an ultra-thin platinum-catalyzed burner. A mere 4 ounces of lighter fluid can produce heat for 24 hours, virtually pollution free.
