The Akeek/Hakeek (અકી /હકીક /अकीक/हकीक ) stone is an important object used in the process of making the manuscript. It is a black onyx stone—essentially a round volcanic rock that has a glassy (smooth) texture. The size of the stone is around 5–6 cm in diameter. It looks like a paperweight that is black in colour, but it is primarily used for polishing the surface of the handmade paper.

Handmade paper is made using the pulp of many fibrous materials. These ingredients make the paper’s surface rough and uneven. The original texture of the paper makes it inconvenient for writing; the Boru occasionally gets interrupted by the rough surface of the paper. Rubbing the Akeek smoothens the paper, and imparts a shine to it; which makes it more efficient for writing upon. Akeek is not only used before writing, but after the writing is completed, as well. This technique is similar to the contemporary technique of buffing the paper which adds lustre to it. Papers which have a smooth texture do not need to go through this process. It is only handmade papers that need the polishing, before and after the writing process.
