X-acto knives are small, handheld cutting tools that are commonly used in art and craft projects, as well as in a variety of other applications such as model-making, printing, and graphic design. X-acto knives come in a range of types and qualities, and some of the most common types include:

  1. Standard X-acto knives: These are the most basic type of X-acto knife, and they feature a handle with a removable blade. The blade can be swapped out for different sizes and shapes, depending on the needs of the project.

  2. Heavy-duty X-acto knives: These knives are designed for tougher, thicker materials, and they often feature a stronger blade and a more durable handle.

  3. Precision X-acto knives: These knives are designed for detailed, precise cutting, and they often have a finer, more precise blade and a handle that is comfortable to hold for extended periods of time.

  4. Electric X-acto knives: These knives feature an electric motor that powers the blade, making it easier to cut through tougher materials.

In terms of quality, X-acto knives are generally very reliable and long-lasting. However, the quality of the blade can vary between different models and brands. In general, higher-quality X-acto knives will have sharper, more durable blades that can withstand more use and abuse without becoming dull or damaged. It is also worth considering the type of blade that the knife uses, as some blade types are better suited to certain materials than others.
