What is the origin of "to the Hilt"

The noun hilt refers to the shaft or handle of a tool or weapon such as a dagger, sword etc. The origin of the word hilt can be traced back to Old English and related to the Old Saxon helta oar handle, Old Norse hjalt and German helza. The words, bottom, end, base, shank, stub, extremity, fag end, grasp, handgrip, etc can be used synonymously with the noun hilt. The hilt of the dagger or sword is the only portion that is visible when the weapon is plunged totally into something. The figurative use of the word hilt came to be first used in 1687 as seen in the phrase “to the hilt” which means completely or to the maximum limit.
