The kitchen store is generally full of pervertibles aka sensory toys with incidental culinary uses. Most recent acquisition: a pastry "dough docker" roller which is basically a mini rolling pin on a handle covered in blunt pointy projection. *cough cough* Ahem. It's important to avoid anything ACTUALLY sharp or hot unless thorough precautions are taken, but for "I wanna hold weird shapes/textures in my hands / run them over my skin" and relatives of that, SOOOO MAAANY options. Plus you can always cook with 'em (provided you buy two of everything so as to not mix uses, preferably) and use that as an excuse.
