The flame rod is a fine thing! Come on my terrace out between the concrete slabs grasses and weeds that I always used to laboriously remove with a scraper had .. and the back could be felt until the next day. The flame rod I no longer have this trouble. Everything is burned and is also no longer so quickly. Ash wegkehren .. ready :-))) Tip: Buy best equal an adjustable gas pressure regulator 1-4 bar with it! This allows you to vary the flame of lighter intensity up jet plane. But please do not use slippers, because it is nice and warm in the foot :-)
