Ivy up a brick wall

[kram]

I have trimmed a reasonable amount of ivy, usually with chainsaw. Two partial cuts and then hit the middle, the lump will ping off with no damage to bark and no risk to chain.

 

A friend has a brick wall garage, lots of inch thick ivy. It occurs to me I have not tried my 3 blade brush cutter attachement yet.  (Used plenty of trimmers). I'll likely do it with chainsaw as it works and its quick, atleast the higher up stuff.

Is a brush cutter blade any good for ivy along the base of the wall? I realise it would need a lot of care, but as I said, not used it before. Good excuse to try a new tool or a bad idea?

 

Thanks.
