You may not be a "polished video guy" but this one is spot on - straightforward, nicely shot, clear, and your commentary has lots of useful points in it. Thanks ! Sometimes Simple is Best. Richard
I think because the actual angle is not very narrow ? so it's not sharp like a knife with a very tapered blade, it's a-bit-less-than-flat but with a well-defined edge. That would make the resulting edge a lot stronger than a fine taper, and given what flail mowers go through, strength is very important !
