Ottcraft Lawn Edger

My most expensive purchase, (never drink and then go on ebay) had to have it as its a little strange, simple geared wheel turning the cylinder along the blade. Bit of a mess when it turned up, rubber tyre came from a castor I picked up, just had to dremel inside diameter, soak in boiling hot water to soften and squees over wheel, best match to original I could find. Lick of paint and done,

Invented by Bernard Sturgess of Ottcraft products, Norfolk, VA, US in1956, took almost a year to have the patent granted from what I can find online, opologies for the bad copy of the advert, but can just make out how it works, if not I've posted a video on Vimeo to see.
