After watching a particular episode of Mad Men "Season 4 Episode 9", I realized that I too use a manual push lawn mower ( great workout right?)as well as DE shaving with vintage razors/new occasionally and own a house built in 1927. Haha I guess I need to drive old school as well.....I got a 3 year old Ford so possibly down the road. I must admit that my gas mower got stolen from my unattached garage so I purchased a used $12 dollar sharpen the blades one and rake up the clippings on my own kind of mower was in the budget. Does anyone else not exactly trying to be "GREEN " or just cost effective ie. no gas or oil just sweat use these? Thoughts?
