Romance Series 18-10 Stainless Steel, Mirror Finish Upon inquiry with the manufacturer, it was confirmed that due to the rise in stainless steel prices in 2009, all 18-12 stainless steel series were changed to 18-10 stainless steel. Therefore, these items are likely to have been purchased after that date. The knives use high-hardness stainless steel for the blade, the same material used in kitchen knives, as they are cutting tools. The handle and blade are connected by welding, which is why the knives are more expensive than the forks.
