So a battery powered weedeater with something that doesn't use wire would suit me fine, as in this wire brush thing possibly...
If you're wanting to do a lawn then I don't think this would work - I think it's more likely to shred your lawn and rip up the surface (could be wrong though). Blades do cut grass well but it depends how many obstacles you have or how close you need to get to walls etc - I greatly prefer them (especially for avoiding the plastic debris - still find bits of orange string from over 10 years ago), but we don't really have lawns.
