I live in a very rural area of Mn. No neighbors within one half mile. My neighbors cats from as far as one mile away regularly visit my yard and are unwelcome guests. They instinctively kill whatever small animals they come across even if they have no intention of eating them. I use live traps in my garden, several types of leathal traps for tunneling pests, and either a 22 or a 12 gauge if those methods don't work. The small pests are under control and a fence keeps the deer out of my garden. Several of the deer that enjoy my landscape plants end up in my freezer each fall. They kind of taste like hostas.

Use 3/4 inch EMT

I am an old but experienced tree farmer, and also very frugal. I have used a 10 foot stick of EMT (electrical matalic tubing)  and the pole saw blade of my choice for many years. Lay the EMT on cement and hammer the end flat. Position the blade on the flattened end at the desired angle and mark the holes. Drill out the holes and bolt the blade on using lockwashers or a nut with a nylon insert. It's efficient, lightweight, dirt cheap, and lasts for years.
