"Knobbly" is just another way to say "knobby." It describes something with knobs – those small, rounded bumps or lumps. Think of a gnarled old tree root or a walking stick with a textured handle. It emphasizes a rough, uneven surface. You might describe someone's knees as "knobbly" if they are particularly prominent. Ultimately, "knobbly" and "knobby" are interchangeable, but "knobbly" might sound slightly more British or old-fashioned.
