Sharpens on demand: the built-in stone attachment hones the chain whenever it dulls
Your chain went dull mid-cut, and every pass after that just burns wood instead of slicing clean. This chainsaw teeth sharpener clamps onto your bar: line up the two pins, lock it in place, then press it against a tree trunk or a log and keep cutting. In about three to five seconds the sharpening stone attachment brings the edge back, and it fits bars from 14 to 20 inches (35.6 to 50.8 cm) with the second pin adjustable to match your holes.

This compact chainsaw blade sharpener goes wherever the saw does, with no bench grinder needed. Keep your hands clear of the chain teeth while you sharpen, and wear work gloves.
