I regard them as self sharpening…. Never sharpened one in my life.Incidentally, tempting as it may be, don't sharpen the blade in situ. Remove it, sharpen it then hang it by the middle off a piece of wire and grind more off the heavy end until it balances. It makes a huge difference. If it vibrates after that, you have serious problems!
Failed or:@James1979 There's a technical description for that......it begins with F.
Only ever sharpened customers ones to be honest. Its more of an expected thing at a service than needed. Although a surprising number need balancing rather than sharpening. God knows what people do to themI regard them as self sharpening…. Never sharpened one in my life.
That blade's been beating the grass into submission.…… with the air impact, What say y’all rightView attachment 294567 or left hand thread?
As long as the grass loses, who cares lol.That blade's been beating the grass into submission.
Anti clockwise please! Unless you are American of courseRight hand, if you look at the blade it obviously rotates counterclockwise which means that the force on the blade (and hence the bolt) is clockwise. So a right hand thread would try and do itself up while a left would try and undo itself.
