Chainsaw blade for angle grinder

I have seen the commercially available attachments and they scare the bejesus out of me. I amour-up when grinding but still have holes in the fingertips of the old welding gloves I wear due to the odd situation requiring removal of the guard,(yes I know it shouldn't be done but there are times....),despite my care in use. Having seen the results of a few chainsaw 'accidents' I have a very healthy fear of the chains.
