Fiskars wins on the uncomplicated compact routine; Corona wins when published cutting capacity and a more purpose-built pruning blade are the point.
These are direct rivals: both are handheld 7-inch folding saws made for branches a lopper will not comfortably handle. Both give a toothed blade, a grip-oriented handle, a folding storage configuration, and a lock intended to keep the blade controlled. The meaningful differences are not cosmetic. Fiskars centers its product around a POWER TOOTH blade with razor-sharp triple-ground teeth, a folding blade that locks in two positions, and Softgrip touchpoints. Corona publishes a more detailed pruning-specific package: a curved 7-inch blade, a stated up-to-3-inch branch capacity, high-carbon Japanese SK5 steel, chrome plating, impulse-hardened teeth, a centered lock, and a compatible replacement blade.
For most gardeners, the Fiskars is the more sensible default because the basic job is usually compact occasional pruning: take the saw from storage, lock it open in the useful position, make a controlled cut, fold it closed, and put it away. Fiskars explicitly says the 7-inch blade locks in two positions for overhand cuts and undercuts, then folds and locks for transport or storage. That two-position arrangement is a concrete convenience for branches that are above shoulder height, below a shrub, or simply awkward to approach.
The Corona is the better alternative when the saw itself is an active part of the yard kit rather than an occasional backup. Corona states that its curved RS16120 blade cuts green or dry branches up to 3 inches in diameter and that the handle covers the teeth when folded. Its blade material, chrome plating, impulse-hardened teeth, and replacement AC 16120-1 point to a shopper who wants to compare the cutting tool as a durable pruning component. Buy the Fiskars unless those Corona-specific features are important enough to outweigh the simpler two-position Fiskars setup.
