This is probably going to get me laughed at, but here goes.
As a photographer I am a total novice, light boxes and fancy cameras are wasted on me, I would expect to get perfect result first off, or I would pack them away and never use them again.
My brother in law is a professional sports photographer so I asked him what I needed to take good photo's of knives. He replied with some indignation, that to post low resolution shots on the internet I needed nothing more than the equipment I had and good lighting. So here goes please try not to laugh.

Setup.
A piece of grey upholstery vinyl draped over the lounge room couch,
Light - Soft lighting app on up to 2 tablets and 3 phones but usually only use 2 as with this photo.

Camera
A point and shoot OLYMPUS u-TOUGH 8000 camera on a small tripod, set to manual, auto white balance, ISO 100, flash off, sometimes have to set to macro to get focus, use the timer so as not to bump the camera.

Other
Various white reflector cards and clamps. mostly I just hold them in my hand to get the right reflection on the blade.
