The big benefit to anvil style is that one can cut suckers up against the trunk.
The blade is very strong - I have never bent a blade as some reviews show, but then I only cut wood with them. The blade does however cut a groove into the anvil surface over time which allows the handles to close tighter together vs when new and your knuckles may bang together.
I noticed corona sells replacement anvils for around $15 - have not tried those yet as the tool is reasonably priced new.
I recommend thread lock on the two anvil bolts because I have had them loosen.
I am very satisfied with these loppers. I have bought four sets of these over the past 25+ years. The quality has been consistent. Well worth the price.
