Thanks to everyone who helped me pick out my first real knife---I finally settled on a 240 carbon gyuto and 150 ss-clad petty from Watanabe-san. They arrived in the mail today, and I can't wait to make dinner with them...but there was a long rectangular cloth in the package as well. I'm embarrassed to ask, because I feel the answer should be self-evident...but what is the purpose of the cloth? Is it to polish? Or dry? Or something more fashionable---It's delicate, like a scarf https://www.dropbox.com/s/e7hwta22rbwp46h/CameraZOOM-20160701185805569.jpg?dl=0
