Oh I like Ibanez very much especially during that period, and neither company put Gibson or Fender's name on their products, it was that they were coping trademarked features.
I saw a karambit on ebay not advertised as a Spyderco, but using the catalog number so I googled the number and this web site came up with quite a few knock offs and some that are not, but using Spyderco name and logos. In the 70's when Fender and Gibson had problems with Ibanez and Tokai, they sued...
That's not the only one they are coping, if you look through they have 222 pages of knives.
It's bad enough stealing another companies designs and trademarks but then to put their name on it too....
