  We present high-resolution, high-cadence observations of six, fine-scale,
on-disk jet-like events observed by the High-resolution Coronal Imager 2.1
(Hi-C 2.1) during its sounding-rocket flight. We combine the Hi-C 2.1 images
with images from SDO/AIA, and IRIS, and investigate each event's magnetic
setting with co-aligned line-of-sight magnetograms from SDO/HMI. We find that:
(i) all six events are jetlet-like (having apparent properties of jetlets),
(ii) all six are rooted at edges of magnetic network lanes, (iii) four of the
jetlet-like events stem from sites of flux cancelation between
majority-polarity network flux and merging minority-polarity flux, and (iv)
four of the jetlet-like events show brightenings at their bases reminiscent of
the base brightenings in coronal jets. The average spire length of the six
jetlet-like events (9,000$\pm$3000km) is three times shorter than that for IRIS
jetlets (27,000$\pm$8000km). While not ruling out other generation mechanisms,
the observations suggest that at least four of these events may be miniature
versions of both larger-scale coronal jets that are driven by minifilament
eruptions and still-larger-scale solar eruptions that are driven by filament
eruptions. Therefore, we propose that our Hi-C events are driven by the
eruption of a tiny sheared-field flux rope, and that the flux-rope field is
built and triggered to erupt by flux cancelation.
