Konhard CS002 (Amazon)
Umm.. claimed to be brushed stainless steel. Looks more like good quality chrome to me. Non magnetic so not mild steel. I'll report back in a few years:-) -- Tim Lamb |

Some Kind of alloy maybe?

Cheap cutlery is often marginal in chrome content, you can get rust spots that can just about be cleaned off with scotchbrite or similar. |

I think the usual response is that it doesn't claim to be stain-free. ;-) Don't leave a Brillo pad on a damp SS sink. Chris -- Chris J Dixon Nottingham UK @ChrisJDixon1 Plant amazing Acers. |

Cheap cutlery is often marginal in chrome content, you can get rust spots that can just about be cleaned off with scotchbrite or similar. Cutlery tends to be 18% chromium and is magnetic (para- only?); 18 10 isn't magnetic and shouldn't rust. I don't know what A2 st. st. is, but it withstands 10 years+ of salt. Rolls Royce wheel trim was 22% chromium and hard chrome plated and polished - that didn't rust in 72 hr. salt spray but the 18% did. -- Peter. The gods will stay away whilst religions hold sway |

Yes. We have some Japanese stainless steel cutlery which can pick up spots of rust in the dishwasher. Interestingly, while I was testing the caddy, I discovered that the knife blades are magnetic but nothing else. -- Tim Lamb |

Cheap cutlery is often marginal in chrome content, you can get rust spots that can just about be cleaned off with scotchbrite or similar. Cutlery tends to be 18% chromium and is magnetic (para- only?) A bit of a simplification. 18Cr 8Ni is austenitic, and non magnetic. Ferritic stainless steels are 13 to 18% Cr and are magnetic. I'd bet that the (non-magnetic) caddy is austenitic stainless. It might suffer rust spotting or staining in some circumstances (like the steel wool case mentioned elsewhere) ; 18 10 isn't magnetic and shouldn't rust. I don't know what A2 st. st. is, but it withstands 10 years+ of salt. ICBA to look it up properly. "A2" tends to be the base designation for stainless steel screws and fasteners, I think it is normally austenitic. "A4" is sometimes called marine grade stainless, that will definitely withstand salt, it has a higher content of alloying elements and will definitely be austenitic. Rolls Royce wheel trim was 22% chromium and hard chrome plated and polished - that didn't rust in 72 hr. salt spray but the 18% did. That's what I would call a Rolls Royce solution. |
