Tapal

The tapal was a weapon that was developed by the tritons. It was considered a closely guarded secret of their species, and tapals were often family heirlooms. A tapal was presented to a triton when an individual became an adult. Older tapals often bore enchantments.

Description
The tapal could be considered a combination of a dagger, spear, and longsword, able to be moved quickly to stab or slash without being slowed by water resistance. The tapal itself was a crystal carved into an arc reminiscent of an angular fisherman's hook, though wider and with a razor-sharp edge along the outside of the blade, with a handle inside the arc. The hook-like end of the arc was meant to stay near the body, while the longer edge and front point was used to stab at enemies while swimming past them. Alternatively, the front arc, a massive but wide tip, was used as a dagger. If the tapal was flipped with the long point forward, it could be used similarly to a spear, with a secondary handle towards the middle allowing it to be gripped with two hands.
