Hi all, A colleague of mine recently received a Misono UX10 Gyuto. When it came I liked how light and balanced the blade was, but other than that wasn't overly impressed with it. A few days ago he asked me to sharpen it for him, and today was the first time I've used it since I sharpened it. There was a noticeable difference in the blade sharpness - it was ridiculously sharp, even sharper then my knives (Kanetsugu Pro-J) series. That said, this was just the first time I've used it - I don't know much about the knives and haven't found too much about their edge retention, performance, etc. Do they hold and edge for a long time, or do they require a lot of maintenance? However, the UX10 series aren't the cheapest - I'm wondering if anyone knows of any knives that are of comparably quality, but perhaps a bit cheaper. For instance, how does the JCK carbonext series compare? Thanks for any help you can provide.
