The term "firmer chisel" refers to a chisel used for carving and shaping wood or other materials. Synonyms for this term include bevel-edge chisel, paring chisel, and bench chisel. Bevel-edge chisels have a beveled blade that can create clean cuts on angles and edges. Paring chisels are thinner and are used for delicate work that requires precision. Bench chisels have a flat blade and can be used for general woodworking tasks. All three types of chisels can be used to create sharp and accurate cuts, depending on the project at hand. Whether you're a seasoned woodworker or a beginner, having the right chisel can make all the difference in the quality of your work.
