Welcome to the forum Ronnie.
Some blade shapes are challenging and difficult to clamp and sharpen with any Wicked Edge models. Even using the LAA it can be difficult.
I would not attribute your user difficulties to a phoney WE. Never heard any issues over a) the years.
Your Case knife is one of those situations where using a Tormek Small Knife Holder may be needed. This holds the knife offset by the handle.
There are lots of work-arounds and accessories I discuss and use for these situations at this group, for Wicked Edge Users: https://www.facebook.com/share/g/F1baK8jyuCHbtv9d/
