The instrument used for grooving wax is a wax carver. It is a small, sharp-pointed tool that is used to create grooves and other details in wax patterns. 

There are many different types of wax carvers, but they all have the same basic function. They are used to create precise and detailed grooves in wax patterns. Wax patterns are used to create dies for fixed prosthetic dentures (FPDs).

The shape and size of the wax carver will depend on the specific task at hand. For example, a small, pointed carver is ideal for creating fine details, while a larger, more rounded carver is better for creating broader grooves.

NKT No. 003 and NKT No. 005 are also commonly used for wax grooving. They are similar in shape to wax carvers, but they have a slightly different tip. NKT No. 003 has a round tip, while NKT No. 005 has a pointed tip.

Spoon excavators are not typically used for wax grooving. They are more commonly used for removing wax from teeth and other dental surfaces.

Burnishers are also not typically used for wax grooving. They are more commonly used for smoothing and polishing wax patterns.
