Thank you for viewing! I have created a gas adjustment knob for the popular SOTO portable burner, ST310/340, which I also use myself. The original burner has a wire-like knob that you turn to adjust the gas flow, but it was very difficult to turn, which was one of the few drawbacks. To solve this problem, I created this custom knob. The brass knob, cut and machined from a brass rod, is very easy to turn, making it easy to adjust the flame, and also adds a touch of luxury. To install, align it with the hole where the original knob was inserted and secure it with a 3mm set screw. *A 1.5mm hex wrench is required for installation, but I will include one for an additional 100 yen if you wish. Please let me know in the comments beforehand. Size: Length: 29mm Knob Diameter: 16φ Weight: 40g Due to being handmade, there may be minor scratches from the manufacturing process. Please refrain from purchasing if you are concerned about this. By the way, the leather belt, leather cover, and the burner itself are not included. Thank you very much.
