They seem to be Isshiki's abilities. Ishiki was based off the Issun-bōshi tale. Issun-bōshi used a needle as a sword, and the hammer called Uchide no kozuchi to make himself grow. That ability Jigen uses is based directly on the needle and the growth caused by the hammer, so it makes sense if Isshiki's abilities were based on the story and Jigen is merely using those abilities because of Isshiki.

Plus, if they aren't Jigen's abilities, it leaves more room for Jigen to have his own cool abilities later on, such as the one that allows him to recreate objects and chemical reactions, which I hope is just one of Jigen's own abilities.
