Well, you have a macro setting and a timed shutter release so I'd say get a cheapo tripod (you can pick them up for a few quid, you don't need anything special for taking a few pictures indoors) bang the camera on macro setting and get it where you want, stick the timer on and let it off. The timer will eliminate any shake as you press the shutter release.
Light boxes are favourites, a simple box can be made with the box your paper comes in. Just line it with paper and you are away. You can out lamps over the top if needs be, you would need to diffuse the light though. Keep trying and you will find the best way to shoot your knives, or send one to me and I'll have a go! It may be a crap effort but a chance to see that knife in the flesh would be well worth it!
