Similar here. I do wood carving as a hobby. I could buy some carving tools, like chisels of various shapes and sizes, and a mallet or two, but I prefer to just use a knife - a normal kitchen knife, a Cartini, somewhat more expensive than a no-name brand, but still cheap. Of course, that means that I cannot create even moderately complex pieces, but that's okay. I am still a beginner at it, and I am fine with creating only simple stuff. I just do it for fun.
After some time, I do plan to research some carving tools, and may buy a few if I get good advice on it, and if the tools seem to make sense for me.
