I have an older model Wusthof Classic 10" which I enjoy to use. (see below pic) Its handle and weight are great. I really like the feel of the bolster as well. Unfortunately, it doesn't stay sharp for long. I have a 10" MAC chef's knife which stays sharp but I hate how it feels. So I wondered if there was any knife out there on the market, that has the weight, handle, bolster of a the Wusthof but the sharpness of my MAC ? misono ux10 ? Shun ? a newer model Wusthof ? Thanks for any suggestions.
