Hey Jim. Yeah, I’ve sharpened the end of the shovel, but chamisa have real stringy roots, and it’s better to chop into them, then pry up as much of the taproot as will come. That generally keeps them from coming back for a couple years. As for the handles, they come from Ace Hardware, and are the TrueTemper 48 (or 45, depending on the year) hardwood shovel replacement handle. Oak or ash would be my guess. They generally split on some short-grain, and I haven’t yet found one at my local hardware store with grain that runs full length without some runout somewhere along the way. Eventually I may turn my own if I find a nice piece of ash or hickory with laser-straight grain.
