Electric hedge trimmers
 

Two questions about corded electric hedge trimmers:

1. Would a Bosch/Metabo hedge trimmer cut seriously better than my
Lidl one?
- Or is it just Leyland's that are difficult to trim?

2. Is there any sense in having the blades sharpened?
- Can it be done?
Could I do it? (Have more than standard woodworker's sharpening
equipment.)

Greetings,
Rob
