Seems to me, it's a design range thought of by mr williams

And anything else other than sensei's official line would constitute as "wanna be" look alikes.
Despite being designated as a purely martial bladed weapon,
It would appear that the vast majority of folks owning these knives would not see any martial use.
Plenty of other great dedicated general purpose or utility cutters out there,
Just know that dedicated stabbing implements are normally intended or optimised for that sole purpose of putting an end to undesirable opponents.
Least one could do is to respect the intended sole existence of any such purpose built tools.
And not dishonor the sensei's brainchild with mundane edc tasking.
Having said that, I do see the point that there would always be calls for higher grade steels for particular individually favoured models.
When this is not possible, the only way then is to seek out the custom knife route.
Meantime, crkt isn't all bad.
The products do seem to have acceptable overall quality for the price.
As with anything else man made, it will never be perfect.
Just as some perfectionist would find the slightest fault with anything and everything.
Luckily for them, there is customer service to pacify their unacceptable and shocking find...
