Dabber

A device that is used to alter concentrates for dabbing. A common dabber will have a sharp point on one end and a flattened scoop on the other. They often look like tools used in dentistry and come in a variety of sizes and shapes. Glass or stainless steel are typically used to make dab tools.

The purpose of a dabber is to avoid burning yourself by transferring concentrates of  onto the hot nail of a dab rig. Different dabbers are better suited for certain types of concentrates because not all concentrates are the same consistency, and some dabbers can handle many different types.
Dabbers with a flattened end are ideal for scooping concentrates with a waxy or crumbly consistency. Try a dabber with a sharp point for sticky concentrates because it will minimize contact with the concentrate.

The most significant advantages of using a dabber are its safety and cleanliness. A dabber will keep you from burning yourself while concentrating on the nail because nails are extremely hot when used.
Additionally, dabbers are excellent for handling concentrates. When dabbing, a little goes a long way, and a dabber will let you be very precise. Rather than trying to use your finger, you can get the concentrate directly from its container with a dabber, which is much cleaner.
