There has been a lot of discussion on terminology.
For example, some people call Shirogorov and Medford knives "mid-tech". But according to the definition of custom as being made by one person, Shirogorovs and Medfords are closer to "custom" than actual "midtechs" by Jon Graham, Brad Southard etc. since Jon and Brad outsource the machining for those knives - the machining isn't done in house on those knives whereas it is on Shirogorovs and Medfords.
Someone brought up the issue of a knife being "custom" if the final edge was put on by the maker, even if everything else was done by machine, Shirogorov full customs for example. Well, by that logic, pre 1998 Microtech production knives are "custom" since Tony Marfione put on the final polished edge on most of those knives, and all the NC work and components were done on machines belonging to him.
When you start throwing around "custom", "semi-custom" and "mid tech" every which way it becomes a mess as these labels no longer allow someone to determine the provenance of a knife.
Some have proposed two designations instead of one: one label to indicate how the knife was made and one label to indicate who was involved in making it. For example, Tom Mayo's knives, made one at a time to fill orders, would be bespoke handmade knives - "custom" would be inherent in "bespoke" as it is for a particular customer'a specifications. Emerson's "custom" knives made for shows (not to fill orders) might be called "handmade custom" knives as they are shaped without NC machines by Emerson alone. Some of Tony Marfione's newest customs could be called "machine produced custom" knives since the blade grinds, chassis etc were formed with NC machines, but all the work was done and components produced in-house with Marfione performing the final fitment and sharpening. The Grimsmo brothers' knives could also be called machine-produces custom for example.
