Meat axes can have a negative connotation as they are typically used for slaughtering animals. If you're looking for a more neutral or positive word choice, consider using synonyms such as butcher knives, cleavers, or choppers. You could also use descriptive words such as cutting tools, slicing equipment, or carving instruments. Depending on the context, you might also be able to use more specialized terms such as fillet knives or bone saws. Ultimately, the choice of synonym will depend on the tone and purpose of your writing, as well as the specific type of cutting tool you're referring to.
