Below are the XRF test results for some unbranded stainless steel chopsticks.
While the XRF does not recognize this metal combination as a specific type or grade of stainless steel, and while these are not expressly marked “stainless steel” (in fact there is no mark on them) I would still put them in the stainless steel category of utensils based on the combination of metals detected by the XRF (namely the presence of Nickel, Iron and Chromium).
Several years ago (2016?) I took my kids out to a Chinese restaurant in Ashland, Oregon (on our drive down to California) and they served us our meal with these chopsticks. It was right before Father’s Day and I was so excited to see stainless chopsticks (which I hadn’t seen before then) that I asked if I could buy a set from the restaurant for my husband.
Sorry I do not have more information about the brand or maker’s name – but I expect these would be the same as any with similar markings (the ridges along the tip) and that you might be able to purchase them at a restaurant supply store.
Personally I think these make a great gift for the Asian food fan in your family!
