I bought this anvil for two reasons. 1) It has an HRc hardness of ~55, instead of only ~50 which is what the blue ones are. 2) Because the picture shows the horn and round hole being flush with the flat surface of the top of the anvil. This second reason turned out not to be the case. There is about a 1/ to 3/8 inch step there. I have since learned that the step is useful for some things but it does mean the round hole is not the same height all the way round, which makes it less useful for using it as a Pritchard hole. I plan to weld some fender washers onto the end of a pipe that will fit in that hole, and then grind one side flat to fit in the hole and solve this problem. The anvil itself is quite good, and for the price is down right amazing. Edges are sharp, so you can break the corners with a file to set the corner radiuses at the size you want. The anvil rings a bit, but I think with a magnet under the horn and a chain around the base this tones it down nicely. (other anvils also ring and can be quieted the same way)

I've used this little guy with my knife working and with some brass working. It is well worth the money especially if you are starting out and don't have a large budget for a bigger anvil.
