I have had some requests for information on competition scythe blades; mostly from people that make their own snaths and want to experiment with off-set snaths and longer blades. I can special order these competition blades, made my Schroeckenfux, from Austria. They are available in lengths 120cm to 145cm. I currently have 120cm, 130cm, and 135cm blades, in stock. They are made of "Hartstahl", a specialty hardened steel, and are factory sharpened, and ready-to-mow. I will get longer blades, as us Americans figure out what to do with them. (see http://onescytherevolution.com/specialty-blades-for-diy-snathmakers.html )
The tang angle on these blades (about 20 degrees) actually does fit the snaths that I sell, but for speed mowing you would need a stiffer specialized snath, as in the video below.
