My swan knife holder is made of plastic material. Like fact lightweight and convenient for moving while cleaning. The needle like pin inside can hold any knife in place of holder. By tight-knit pins knives will not fall out easily. Securely tuck any blade hidden deep down. Safety is first priority. I did receive this item at discounted rate for my testing experiences.
