This is a Taiwanese knife. It can cut by pushing or pulling, so it's often used in fish markets. Once you get used to it, you can quickly fillet fish of various sizes, so it's worth trying. Personally, I think the fillet knife I have listed is easier for anyone to use, so this one is more for intermediate to advanced users. You can find how to use it on YouTube by searching for keywords like "Taiwan knife fish market". Kimagure Cook also introduces a similar knife.
