Do you sharpen your tools?
I must admit, I've been very bad at this. In fact, I've probably only used a whetstone a few times on a few tools in the years I've been gardening. It's one of those things I really mean to do and tell myself each year: "This is the year I do it!", but I never do. (That other thread about the hoop hoe got me thinking about this)
Plus, the other day I was trying to chop a massive climbing rose out of the ground with a clearly, dull axe and thought: "I bet this would work better with a sharp axe."
So - shame me, inspire me, tell me what you use. I want to get into a new habit.
