The catch is ok in itself. Processing not like a knife Schweitzer, not stainless steel. But after all, ordinary processing with no sharp edges, even if you visually see a ridge. Spring mechanism is taut. Irritates me a little, that nowhere the logo of Victorinox Swiss Made, or at least is imprinted on the hook. My copy was sold by the dealer "Swiss army knife" Delivery via Amazon. It came in a little worn Platiktütchen on which bag plain, created by the seller sticker with production name; no further information on material production site. All in all a good little carabiner - with questionable Swiss origin.
