Palak was an ancient weapon or relic called a "star blade" that was stored in the Kawatche Caves which gave Kryptonian-like abilities to its possessor, which would eventually corrupt them. It is also part of a prophecy saying that it will, or can, shine in the presence of Naman's archenemy.
The legend of Naman tells that the original visitor left Palak in the wall of the Kawatche Caves for the Kawatche people to safeguard.
However this weapon's used, it is a rustic knife-like object. An intense light is seen riding up the shaft of the blade, as if it were somehow connecting with Earth's yellow sun, as seen when Jeremiah touches it. 
Powers and Abilities
The wielder was given abilities closely similar to Kryptonians, which overtime would eventually corrupt the person's mind. These abilities are coursed into the wielder after they pick it up and a bright light rides up the blade. Because of its importance, this abilities were given to the wielder to protect it until it could be delivered to the true Naman. The wielder is described to have the strength of ten men, and being able to start fires with their eyes. The wielder was also given super speed, invulnerability, and healing factor. The original traveler who left the blade in the caves for the Kawatche people, probably demonstrated some of his abilities to them, which is how they know specifically about some of the prophesied Naman's powers. Its abilities could only be activated while in the possession of someone and without a wielder, the weapon's sacred abilities are left dormant. 
However, the user was immune to the effects of kryptonite, suggesting that the powers given by the blade are derived from an internal power source which doesn't transform the wielder into a real Kryptonian. Give that most Kryptonian minerals are affected by a yellow sun, it's likely that it has absorbed yellow sun light for hundreds of years and then converted this energy properly to bestow the wielder temporarily with superhuman powers, as long as he or she was touching the device. 
After Lionel Luthor took over LexCorp, LuthorCorp gained jurisdiction over the caves. Convinced the caves contained the secret for curing his terminal liver disease, Luthor commissioned studies and excavation which unearthed the starblade. 
The starblade was then taken by the Kawatche student Jeremiah Holdsclaw who received the power from it and thought himself to be the Naman of the legend. After his attempt to kill Lionel whom he thought to be Sageeth was prevented by Clark, the starblade stuck in a rock that was to be used as an altar for the sacrifice. When it was simultaneously touched by Lex and Lionel, it crumbled to dust, leaving it uncertain who of the two was Sageeth. 
- Though the legend says the wielder would be given the strength of ten men, the super strength actually acquired was far greater than that as seen in the fight between Clark and Jeremiah.
- Lionel tells Clark that he thinks that the metal that makes up the blade is same type of metal that makes up the octagonal key (to Clark's ship).
- Since Lionel is dead, it can be assumed that Lex is in fact the true Sageeth and the one who touched the blade first.
- The original traveler who left the blade in the caves for the Kawatche people, probably demonstrated some of his abilities to them, which is how they know specifically about some of the prophesied Naman's powers.
