Barbs are the small hooks which protrude from the length of the tool, pointing towards the handle. They catch unwanted clogs when inserted down the drain. They sometimes run along the whole length of the tool or are reserved to a section at the tip.
Length of a barbed drain unclogger
The length forms the majority of the tool. It is thin and bendy, ideal for manoeuvring drains. The length of the whole tool can vary between 60-75 cm (23 5/8″ – 29 1/2″).

The handles can vary slightly in shape from model to model, but all have a finger loop to hold and manoeuvre the tool.
