I think you could pretty much take the top dozen knife makers, compare their range of knives, finding that some are so similar, that they must have copied from each other
Or, maybe that over decades, people have found that a particular shaped knife works best for bushcraft, skinning, gralloching, a boar knife, etc' !
And then, having a knife that crosses over, would be common sense, such as a gralloching knife, that skins the animal too ?
Even MORE interesting, I just googled "Antique Butchers Knives", and the general shape of the Cael, has been around before either of the knife makers concerned were even born, it's just a smaller version for deer, rather than what a butcher might require !
I have met the guys at Emberleaf and frankly seeing the work that goes into every knife it’s truly amazing they are priced as low as they are.
You, and I have had this conversation before, and I PM'd you some pricing FACTS. I see you're still wearing Rose tinted

then
