The K2 Stove is a new design in flat-pack camping rocket stoves, which reduces fuel requirements and reduces smoke emissions through the efficient use of wood. 
 
Designed and built in the UK, the K2 Stove has very sturdy construction, fabricated with 1.2 mm thick stainless steel, and weighing just 1.4 kg. The improved K2 stove has just 8 pieces: 4 for the flue, 1 fuel tray, 1 ash tray and 2 pot stands.
 
Assembled dimensions: 28 cm tall, with a 10 cm x 10 cm flue, and a maximum width of 19 cm out to the edge of the firebox. The pot stand is 20 cm wide, and the assembled stove can easily take pots up to 28 cm diameter. The tray at the base holds the ash from the fire which can be disposed of when the cooking is completed and the fire has cooled down. This stove is designed for outdoor use only.
 
Included is a cloth carry bag made out of up-cycled curtains or other material donated or bought in charity shops. For this reason the design of fabric may change from those shown in the photo.
 
The stove uses small pieces of wood as fuel, and is very easy to light. Once the fire is up and running and the stove is nice and hot (which takes 5 to 10 minutes in normal conditions), the stove can boil a litre of water in under 10 minutes.  Full instructions are provided.
