Thank you for the video, it answered many questions. I have a small section of drainage ditch that used to have cattails in it, but, as time has passed and now 20 years later they have given way to phalaris grass which is rather densely populated and quite tough. I have used a gas and electric string trimmer with varying success depending on what part of the growing season is. Early in the season the string trimmers work OK, later as the stems toughen up it becomes the wrong tool for the task at hand. I have thought about trying to find a scythe at a local garage sale or auction. Although when using one at my grandparents farm 55 years ago in my misspent youth I don't remember using it in late season phalaris. I remember seeing old black and white movies years ago of jungle exploration and Tarzan and seeing a machete cutting thick heavy vine and knowing it was Hollywood's version of things I had harbored some doubts about it's ability to cut through old possibly dried out vines. Well, the fellow in the video showed me how it is done! I am thinking I am very glad I have been following this thread, now I just need to figure out length and blade style and ... .
Is there a formula for figuring out how long a blade a 6'2" guy should use?
