At the start of the season I use a half-moon cutter to push away the soil and sharpen the edges and then I just cut them with long handles shears @D0rdogne_Damsel . Must admit I have a bit of a thing about neat lawn edges it makes the garden look good even if you don't get the chance to mow or weed.
