The latest posted photo I saw of the 'rat folder' has two features that need attention, in my opinion.
The choil cut-out:
If it's not large enough to accomodate a forefinger, what purpose does it serve? Enlarge it or forget it.
The thumb-placement area on the spine:
Mill some serious non-skid cuts for firm thumb purchase.
For clarity, examine the blades of the Spyderco Military or Strider SNG/SMF folders. The blade ergos on these blades are outstanding - very superior to what I saw on the 'rat folder' proto photo.
Everything else looks just fine.
This advice is worth exactly what you paid.
