ther are more types of scythes, most of them are for tall grass or wheat or whatever grain plants, the blade is longer and thin
if actual weeds are your problem and there are rocks you might hit that you dont see in the weeds or its all at an incline, there are short bladed and stubby looking
you will also have to learn how to swing, with bad technique and unadjusted scythe handles you will break your back in 2

you also need a sharpening stone, you will notice with good technique when the blade is dull
you also have to learn how to sharpen the blade
it all takes some practice before being able to effectively use
