E of SN tells me they originated in Ireland as the preferred brew making apparatus of profesional seaweed gatherers, and with the design's ability to be carried full of water and stay alight in wind and rain, its a highly plausible origin story.
A big advantage of the Stormkettle F1 is
the neoprene cover which both retains heat and protects fingers.
I've seen and used quite a few Kelly's over the years, the Aluminium models are obviously slightly superior in their ability to transfer heat, and the stainless steel editions slightly better in their ability to resist dents. A lad on Kickstarter was claiming to have invented the idea and was making his out of Titanium. While there are very few titanium things I havent bought over the years, the model from thestormkettleshop.com is I hope the best of both worlds. Ti is light, strong, corrosion and stain-proof, but its a pretty crappy transmitter of heat and ofcourse carry's a price premium that I'm not able to stretch to this week.
This puppy is Aluminium with an anodised finish and so far it seems very good. The other thing I liked about the F1 Storm kettle is it's a brew-kit, just enough water for two cups and not going to take up too much real estate in my fishing bag. I would have bought one years ago, but I've never seen one this petite before: Capacity: 0.5 litres Diameter: 12.5 cm Height - with fire bowl in: 20 cm Weight - empty: 450 g. Most of the companies around the world making Kelly Kettles will sell you gadgets to balance a frying pan on top. Forgive my cynasism but I reckon I'm just too clumsy to cook my bacon and eggs on such a device. The whole kit and kaboodle would be on the ground before the water was boiled.
PS yes I'm embarrassed to admit I drank instant so-called coffee
