In particular, the scraping of longer and not quite as narrow joints, eg. At the bottom of a garden wall, this saves a lot of time Scraper. Unlike joint knives he does not hang on the edges of stones, which is why you have the bit wider joints in a very short time "swept" weed-free. With narrow joints on the sidewalk unfortunately removing the weeds no longer works so quickly and easily, but is still enjoyable to perform, as with a normal joint knife.
