This is a carving knife and fork set. It has a solid stainless steel feel, but there are some rust marks, so it doesn't seem to be made of a completely rust-proof material. The brand's engraving has worn off, so I don't know the brand, but it looks very similar to the Nenox (Konohi) meat fork, which is a top-of-the-line knife brand. Apparently, a fork from Konohi alone costs 60,000 yen. This belonged to my grandfather, who loved camping, and it has damage such as rust marks and scratches. Please refer to the images. Please purchase only if you understand that this is a used item.
