This is a great way to get rid of weeds on patios or between paving stones without resorting to chemicals. It's also effective for removing ice from walkways. Because you can kill weeds by applying only enough heat to shrivel them, you can cover a lot of area quickly with this 100,000 BTU torch. We offer two models. The original torch produces a continuous flame when ignited, suitable for covering larger areas. Also available with a flame-control squeeze valve on the wand that lets you minimize the flame so you don't waste propane while moving from spot to spot.
