I recently put a diver's knife and sheath in the freestuff. I made it completely from scratch using: my MAKEOBJ modelling utility; a real (not mesh model) diver's knife and sheath; a ruler. Just now I received this message from Kruse:- "Hi Anthony, please, be so kind and remove your divers-knife out of the free stuff. It's of rather similar kind to our item, which you bought some weeks ago. Please understand our demand for this matter. Regards Matthias + Daniel Kruse As my knife model does not contain any of Kruse's model, am I under any obligation in this matter? And how can I avoid annoying Kruse? I regret that I do not remember buying a diver's knife model a few weeks ago. I do not want to start a war with Kruse. In my diving models I have been using an adapted version of a "thigh dagger" which I downloaded somewhere, but recently I felt a need for a more realistic model, so I made one. I did not know of any diver's knife models in the marketplace. Presumably these two models look like each other because they both look like diver's knives.
