It could be argued that without the χ-blade, the Keyblade War might never have been waged; after all, you cannot possess what you cannot find or unlock.
It is clear the blade was the inspiration for the human-wrought Keyblades. The letter χ can be pronounced both "key" or "kye" (leading to some confusion) and symbolizes the perfect crossing of light and darkness. The χ-Blade can be forged via a high-dimensional clash between those two poles.
It is believed that the Recusant's Sigil also derives from χ.
