Casket Revolution 51ML. A 1 & 1/2 fast taper with a very easy-to-use length. The previous owner had the blank custom-made by a shop. It has titanium K guides, making it more user-friendly and lighter than the official model, resulting in increased sharpness. It has 7 guides. Several guides from the top are larger than those found on high-end models like Souls Explorer and M&N Corporation, making it easier to use. I haven't had a chance to use it since I bought it. It has no signs of use, and the guide threads are neatly wrapped with no issues. I am selling it because it's difficult to obtain a Casket rod with a good quality boron handle and blank. Please consider this item with the understanding that it is not an official product and is a custom build that has been handled by someone else. *Price negotiations will not be accepted. *Please see my profile.
