The dapur of this ancient keris is called 'Mahesa Lajer', sometimes also known as 'Kebo Lajer', a traditional Javanese keris model. Since time immemorial, kerises featuring the dapur Mahesa Lajer have always been a most popular heirloom item among the indigenous people from Java, especially among people from the lower ranks in society, such as farmers and laborers.
Many keris collectors and admirers believe that the keris Mahesa Lajer has special powers that serve the needs of farmers and hard working laborers. The mystical powers ascribed to this dapur are said to be able to provide blessings of fertility, thereby preventing bad harvests, epidemics, and cattle plagues. Likewise, the keris Mahesa Lajer can quickly turn one's luck around by removing bad luck and changing it for good luck. Its esoteric content is thus capable of improving the outcome of one's deeds (i.e. karma), which obviously enhances one's fate as well.
In the past, village heads, town councils, regents, sultans, monarchs, political leaders and state officials all would keep a keris Mahesa Lajer to provide them with blessings of protection for their land. In this way, then, the keris Mahesa Lajer serves as a guarantee to sustain fertile land and to provide a good harvest, as well as preventing epidemics and plagues.
Though this keris is nearly five centuries old, yet its pamor pattern is still entirely intact. The blade features a most graceful Wos Wutah pamor motif. Obviously, the Wos Wutah pamor pattern goes hand in hand with the dapur Mahesa Lajer, for this is perhaps the most authentic Javanese design for an antique pusaka heirloom keris. 'Beras Wutah', as Wos Wutah is called in Indonesian, represents sprinkled rice, which, of course, is an important symbol of surplus food, indicating wealth. Thus, in combination with the traditional Javanese dapur, the keris Mahesa Lajer can bring its owner manifold blessings of protection, good luck, and good fortune.
