Best Gardening Gadget

Mine looks pretty lethal, and could certainly do some damage if used in anger, due to the sharp point. But the edge is not sharp really (especially if you use it to scrape mud off tools ), I can't imagine cutting myself on it. The versions with one serrated edge could possibly be a bit more dangerous, but I've got the standard Niwaki.
I only used it for a bit of weeding today, as we were mainly cutting back grasses (with sickles).
