I think some clarification seems to be in order here. There was at one time a Custom Shop that was part of the factory in El Cajon. They made the special runs of knives that were sold through the catalog/dealer network. A good many of the older bowies, daggers, etc were made by men that had perfected their skills into an art. My understanding is that any knife made in the Custom Shop was stamped as such. It is also my understanding that every knife that Buck makes must be stamped with the Buck name - no exceptions. Unfortunately, the original Custom Shop no longer exists. These days, Buck still produces special runs and limited editions, but not as they used to.
Buck also has what they call Pete's Custom Knife Shop, a part of their web site, where one can design, and order, Buck 110's to their own specifications changing the blade steel, and scale material. These knives are stamped Custom and Designer's Choice - and there is no option for them to not be stamped. It does not matter which knife steel you order on your knife, standard 42 HC - ATS-34 - BG-42 - Damscus, or what finish is applied, it will be stamped "Custom" and "Designer's CHoice."
At this time, the only knife that can be ordered from PCKS iss the 110. A number of us have been asking the factory to offer differentr models, and they have said in time they probably will. Then again, we have been asking for a long time.....
