Debating over what qualifies as a traditional knife is kind of like arguing about what a classic car is. Several car manufacturers have made modern renditions of classic cars, for example, the Challenger, Charger, Mustang, Camaro, etc. The new models of these cars, although they are being made by the original manufacturers, are by no means classical cars. They are modern renditions of the classics, and by no means fall under the definition of what a classic car is. The same goes for a traditional barlow. There are certain criteria that a knife needs to meet in order to meet the qualifications of a traditional pattern, and these criterion have been clearly and repeatedly defined. It isn't really up for debate, the knife either qualifies, or doesn't. Personal taste has NOTHING to do with it.
Lets take the "Beerlow" for example. This knife is not a barlow, it is a bastardization of the barlow. It may have shared aspects, such as a barlow style bolster, and a traditional barlow handle pattern, but, by definition, it is not a barlow. No personal opinion there, just pure fact.
Having said that, I (obviously) do not see anything wrong with making changes to traditional patterns to meet the demands of todays market. I do, however, have an issue with grouping them into the same category. Don't claim to drive a classic car when, in fact, you drive a '14 Challenger.
I am, of course, using the general "you" in this post. It is not directed at anyone in particular, but just my personal opinion on this general discussion.
