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, made by cutting and machining a brass rod, is very easy to turn, making it easy to adjust the flame, and also adds a sense of luxury. To install it, align it with the hole where the original knob was inserted and secure it by tightening the 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 advance in the comments. 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. SOTO ST 310/340 Brass Gas Adjustment Knob Mabo's Throttle #Mabo'sSurvivalGear Type of cooking tool: Burner
