How wide is the flame? I was thinking of getting something like this to sear my food after I sous vide it so I don't have to deal with the hassle of using my cast iron pan, but a colleague who bought a torch for similar reasons said that it's not practical. He complained that his torch (which is probably a different manufacturer) heats up such a small area at a time that searing a chicken breast requires tediously inching the torch up and down the chicken in narrow strips, and it takes so much time and effort that it's just not worth it.
WashingtonGuyVery good question! I will share with you that the flame is 7.5" long and the width is about 0.5". This tool is perfect to use when making sous vide. I can promise you that you will not regret your purchase!
