I have purchased from Northwest Knives before and all I can say is the customer service is top notch.
Regarding the clips...they are awesome. Until I got them, I didn't think you could make my Sebenzas or Inkosis any better. It's as if the knife should've come from Chris Reeve with these clips to begin with. They really complete the knives.
