Help identifying a hamon pattern


A year or so ago-I remember watching a short clip of a sword maker in Japan who created the most unique hamon pattern I have seen so far-it was a kind of “criss-cross” pattern he made with what looked like a very small brush or a piece of straw. I will attach a drawing of what it looked like. I’ve looked for the video but can’t find it and also cant find any examples of it online. Please take a look at the drawing and if anyone knows what it’s called or has an example photo of it please let me know! Thanks for your time
