What are the differences between the two TF series Nakiri's? I know they both use the same high heat treated W#1 steel and visually the Maboroshi has a hammered finish and a finger cut out on the blade. Is the price difference worth it compared to the Nashiji version? I have heard that there have been some finish and inconsistent grind issues on the lower priced Nashiji's. Do you get a better quality blade purchasing the Maboroshi. I am looking at the 165 Nakiri. Thanks Bill B
