I have recently bough a Fallniven Odin NL2 and the knife is really good and I like it very much. But I have a little problem. Sometimes when I cut something a little bit more hard the handle creaks. I am not sure that this is the correct word for this, but it sounds like two part are grate each other. This sound is very short. It is only one "tick". I do not know how to explain with my poor English. it is not a big deal but it is annoying. I have tried to unscrew the bolt at the bottom of the handle but this thing is just unscrewable. Moreover it is very soft and I have already scratched it on some places. So I would like to you ask you people what should I do? Should e try to find such specific screwdriver and unscrew the bold and just look inside what is making this sound and try to fix it with some glue or put some gasket. It seems the sound is not coming from the blade inside the handle but it comes from the handle itself, because the sound appears when I hold the handle with two hands (with three fingers only) and try to bend the handle. The creak is short - only one "thick", but can I fix it? I would like to hear your thoughts about that, because I am clueless. 
I hope you have understood me.
Thank you.
