Stiletto

Stiletto is a small piercing blade native to the New World.

Description
Stiletto is a weapon originating from the New World. Even if Ainz were to use data crystals, he would not be able to craft this type of weapon.

Appearance
A long slender blade with a needle-like point.

Abilities
While having no magical abilities, it was primarily intended as a stabbing weapon. Additionally, the stiletto possessed what is known as a "Magic Accumulate enchantment."

Also, it seems apparent that Magic Casters such as Fluder could imbued various types of tier spells into this weapon. As they are stored into the stiletto, the user will attempt to use the magically-enchanted stiletto to land a physical hit onto their target, then later activate the imbued spell upon contact.

Although the act of doing so would expend the spell, that stored spell could be just about any sort of magic. In a way, it was a useful handy enchantment which allowed the owner of this weapon to prepare for just about any situation with the right stored spell.

However, by doing this, the spell is consume and needs to be recharge again by its enchanter. Despite the stiletto not being a magical weapon in and of itself, it can still become one temporarily.
