Thought about having the machine shop make me up some sharpened AR500 lawn mower blades for my old mower, that still runs just fine, and seeing if that 40 year old beast will tackle them.
Something with a circular saw blade on it. Weedwacker or similar. This would do it, but looks like a lot of work... Amazon product ASIN B093CN1DKS
