Wood is most often scraped when finishing wooden floors or renovating furniture. In any case, it is more convenient to replace the steel scraper with a piece of window pane, especially then, when we have a larger supply of such glass no longer needed for other purposes. The edge of such a glass scraper must be convexly arched (never straight or concave). Such a scrape is obtained by breaking a piece of glass and selecting only parts with an arched edge. The advantage of this scraper is a very sharp scraping edge.
