I have mentioned this in the last thread but thought it really needed a separate title. I have just taken delivery of a new Commemorative Urban Raven from Christine. It is one beautiful knife. I hope I can explain this properly. The problem is that initially I couldn't get the knife out of the sheath no matter how hard I pulled. Eventually, I had to get a large screwdriver and put it into the kydex lip above the part of the sheath covering the guard and lever the kydex apart (on one side of the knife the guard is in the kydex sheath, but not the other side). By levering the kydex open, I was eventually able to extract the knife. But now I have it out, I can't get it back in. The kydex lip closes up tightly and there is no way the thick guard on one side can get past it. Is there some technique I should be using to put my knife in and out of the sheath or have I struck a faulty sheath? I really want to use this knife, what can I do to fix the problem?
