Iused to use a "jury rigged" inverted propane cylinder and attached nozzle afixed to a metal rod for the purpose of burning small unsightly weed seedlings, which would regularly pop-up between my driveway pavers and patio blocks. The problew with my "jury-rigged" set-up was that the inverted propane cylinder eventually allows liquid propane to seep into the torch nozzle and either created dangerous flare-ups or just caused the flame to extinguish. Also, the stock propane nozzles used for brazing/soldering would constantly "flame-out" due to the flame coming in close proximity to the pavers and would therefore cause the flame to blow-out/extinguish itself. The Bernzomatic JT850 Self-Igniting Outdoor Torch is engineered to maintain an upright cylinder position, eliminating all the inherent problems found with my "jury rigged" set-up mentioned above. Now, this tool is the right tool for the right job! Once you screw on the propane cylinder the tool is perfecly balanced and easy to handle. Open the valve, click the quartz ignition switch and you have a "jet-like afterburner flame" which will not flame-out and along with a accompanying satisfying roar, makes quick work of any weeds which dare to have poped-up between the bricks. Once you get the weeds eliminated and under control, maintenance is easy and actually fun? My entire circular driveway is now pristeen and weed-free and when new weeds appear, they are quickly eliminated, with just a momentary application of the searing flame. I belive, in additon to killing the visible part of the weed, the seed is also damaged by the heat as well, so new weeds appear less and less often. If you have pavers, or sidewalks, or even a cracked weed-prone concrete or asphalt driveway then I would definitely reccomend this tool. It is a quality piece, safe to operate (usual open flame cautions apply) and I actually look forward to the weed extermination exercise! I had considered a "knock-off" cheaper model, but luckily I stumbled upon a few owner reviews on those models, which complained of "flare-ups" and other inherent problems with the cheaper tool and decided to go for the more expensive "Bernzomatic JT850 Self-Igniting Outdoor Torch" and I am glad I did! Buy this product with confidence and look no further! If small weed elimination/maintenance is your goal, then this is definitely the tool you want to have in your arsenal! You'll be "weed free" in no time and you might even "enjoy the hunt" when they dare to return? Enjoy!
