Here is another power, a conversion of the 3.5e Glassteel spell, which was cut due to space (leading people to wonder how Glassteel could exist). It makes sense that Athasians would have a psionic power like this. It’s high enough level that it won’t make a dent in the metal shortage.
In the harsh expanse of the Athasian wasteland, the mul psion Kael stands at the edge of a rocky outcrop, an obsidian sword held firmly in his grasp. With his eyes closed, he channels his mental prowess, perceiving and altering the very internal structure of the obsidian. Time stretches and bends as Kael’s mind orchestrates an unseen symphony within the heart of the blade. When he finally opens his eyes, the world resumes its normal course. The obsidian sword, once brittle, retains its sharp edge, but is now as resilient as the hardest steel, forever transformed by the sheer force of Kael’s mind.

This power increases the hardness and hit points of the targeted object to match that of iron or steel (hardness 10, 30 hit points per inch of thickness). If the object already has a higher hardness score, the power has no effect.
Augment: For every 2 additional power points you spend, the hardness of the object increases by 1, up to a maximum of 20 (the hardness of adamantine). The hit points per inch of thickness increase correspondingly by 3.
Objects affected by this power cannot be turned into permanent magical or psionic items.
Here is another conversation of a Pathfinder spell to psionics.
Subliminal Speech
Discipline: Telepathy [Mind-Affecting]
Level: Psion/wilder 2
Display: Auditory
Manifesting Time: 1 standard action
Range: Personal
Target: Self
Duration: 10 minutes/level
Power Points: 3
This power grants you the ability to send secret messages embedded within your normal speech. This is similar to the secret messages ability of the Bluff skill, but no check is needed; your intended recipient always understands the hidden message perfectly, while others cannot perceive the message at all. You can send only one message at a time, though you can send that message to multiple recipients.
The secret message is considered to be in the same language you are speaking, and intended recipients hear and understand both your actual speech and the secret message. You can make yourself understood as far as your voice carries.
For example, in the bustling markets of Nibenay, a shrewd slave trader manifests this power before stepping up to auction off his latest acquisitions. All around him, potential buyers hear his enticing descriptions and exciting promises about the slaves on offer. Yet hidden within his public words are secret instructions to his proxies scattered in the crowd, nudging them to raise their bids and stoke the competitive spirit of the market when he sees an eager but hesitant buyer.
Augment: If you spend 4 additional power points, this power’s duration is 1 hour per level rather than 1 round per level.
