It's always my pleasure to do so. I use knives to re-arrange the lighting for other things I'm working on. It's also nice to see if I can re-shoot them so they are better than the last ones I posted. One tip I can offer to everyone is to not use fuzzy red backgrounds. Everyone picks out something red to use. Red is like acid. You're better off using something, non reflective, smooth and not over saturated with color. Brown paper bags and manila envelopes and wood works pretty good. Think smooth (not carpet, towels, fabric etc.) and not too much color. White is fairly hard to get a good shot without using a photo editor. The idea is to show off the knife, not the background. Don't mean to cause a row, just my 2 cents.
