Small metal pipes equipped with screens are widely available and commonly referred to as metal pipes, hand pipes, smoking pipes, or sometimes "one-hitters" or "bats". The screens serve an important function by filtering ash and keeping unsmoked material from being pulled through the pipe.
- Material: They are typically made from durable metals like brass or stainless steel, which are heat-resistant and easy to clean.
- Screens: The screens themselves are usually small, circular mesh filters made of stainless steel or brass and can be purchased separately in various sizes (e.g., 1/2 inch, 3/4 inch).
- Portability: Many designs are small and portable, intended for discreet use and easy transport, often described as pocket-sized or one-hitters.
