If copying an existing design means custom, well, that' not what I meant. I see Steve's point that it was a custom knife in that it was hand made, not production. I was trying to add the dimension of being uniquely different and to the customers order, at which it fails (to me) because it is a copy - not new.
That certainly has nothing to do with the quality of work or use of materials. The problem of defining custom is an old argument, as Rick rightfully pointed out. Is his work custom? In my opinion it would not be unless specially commissioned to follow the customer's design, as I pointed out using the Randall first hollow handle design. Had a CNC been used on that, it would still be custom, and as a machine probably did form the hollow handle, the focus of my example is design, not method of tool used.
I certainly don't want to suggest that using a CNC doesn't make it a custom - but it certainly adds to the repeatability in making production knives more quickly, even if that production only amounts to the hundreds per year.
I work in a CNC shop, making parts for truck cabs, which are optioned enough as a finished unit to be condsidered custom in some instances - but there are also stock production units made to simply supply the market as described in the catalog. I also owned a '66 Mustang for 18 years, and when I sold it, it was custom - major parts installed never offered by the factory for the model year, body work done to be different, paint color applied never offered on any Mustang. That may not be the way the knife industry defines custom - and as Rick accurately pointed out, that discussion is still going on.
Doesn't mean I wouldn't own one of his knives; I bought a Strider because I saw features that suited me, and I just might customize it, too. Custom just means uniquely different from the rest of the herd, like Sebenza graphics. But again, whether CNC or not, if it's a catalogue item and one of hundreds that year, year after year, it's not custom.
And it really doesn't matter, as everybody is still happy with the knife and the check.
Imagine hand sawing, cutting, filing and finishing a Titanium framelock -they'd be the price of an engraved Belgium Browning . . . .
