Honsen Two scraping blades, eye remover

The listing does not say, and on a peeler that is the question that matters most. A swivel head is mounted so the blade can pivot a few degrees: pulled along a potato, it follows the curve and takes a thin even strip. A fixed blade does not, so on a round vegetable it digs in at the start of the stroke and skates at the end, which is both wasteful and how people gouge their knuckles. Honsen calls them "two tough scraping blades", which describes the cutting rather than the mount. Every other twin-blade peeler on this shelf states it explicitly — Zulay ("swivel design... dual sharp blades"), Spring Chef ("swivel to glide"), OXO ("swiveling twin blades with flexible action"), Rainspire, Farberware ("stainless steel swivel blade"). Assume fixed unless told otherwise.

Digging out the sprouts and the dark spots, and seven of the twelve peelers here have one. A potato eye is a growth bud sitting in a small depression, and the dark ring round it does not peel away with the skin — you have to gouge it out. An eye remover is a small pointed loop or hook formed on the end or the side of the peeler, so you flick the eye out without reaching for a knife. OXO Pro describes the action best — a "sharp eyer easily removes blemishes in one scoop". The peelers here without one are both KitchenAids, the OXO Julienne, Farberware and KITCHPOWER — which is fine if you buy washed potatoes and a fault if you buy sacks of them.

"Stainless steel", and no more than that — which is true of nine of the twelve listings on this shelf. The grade is what decides how long an edge lasts, and only the two KitchenAids publish one: 420 stainless, which is the right family for a cutting edge because it is martensitic and can be hardened. The two listings here with carbon steel blades — KITCHPOWER and FUHUY — are using the metal that traditionally takes the keenest edge, at the cost of rusting, and FUHUY says so outright: carbon steel "better than stainless steel". Where an ungraded stainless blade sits between those is not knowable from the page. At eight dollars, treat it as a consumable.
