Favourite garden tool or device

There are plenty of helpful tools and gadgets that we all keep in our shed/garden but what’s the one you keep going too make life easier? Mines a long and short version of the same tool, a 3 pronged hook or cultivator. Great for scratching the top few inches to weed and prepare the ground for direct seeding. Weeding between rows and plants and I use the long handle for pressing into the soil for row depth and spacing. Great for spreading mulch around small seedlings. What’s your fav go to device?
