I had the same issue and like you said I just put duct tape on each side inside and it has worked great the last 3-4 yearsI assume you are talking about the Garberg. It was the all hard plastic grip that I really didnt like as well as the plastic sheath wouldnt keep the knife in. I realized however putting a little tape intide the sheath made the retention 100% and the lack of Kansbol style rubber was actually far more durable and comfortable when using the knife for a while. Mine has since been convexed and is really a great blade. The steel is soft and very stainless which I have come to really enjoy using outdoors.
