I don't have any custom or handmade kitchen cutlery, but if price is not a factor, then that is probably the way to go. They can be made to the most discriminating or idiosyncratic specs, with excellent heat treat of excellent materials. No doubt they will deliver greater performance and better comfort than factory blades.
After researching factory kitchen cutlery for about 4-5 months, in Nov and Dec of the "last century" I purchased two Kyocera ceramic blades (no, not steel) and a discontinued Spyderco 9.5" chef's knife w/AUS-10 (57-58 RC) and micarta scales. All three vastly outperform all other kitchen knives I've used in the past, for less than the retail price of equivalent Henckels or Wusthof models. (After researching them, IMO, their performance does not nearly justify their prices.)
Two final notes: 1) the ceramics do indeed keep an edge far beyond any stell, and are not nearly as fragile as most folks imagine them to be. 2) The discontinued Spydercos are still available through their outlet at less than 40% retail. When they're gone, they're gone for good -- one of the best kept secrets around right now, IMO!
