You might want to also work on you're photography and presentation. This might sound mean but it is only intended to be constructive... You have your knife sitting on dirty shag carpet. Even if the knife was perfect, the background makes it look bad. It's not a big deal if you're just posting up to show the knife for advice but you're also using those pics in your for sale thread.
You don't need a high dollar camera there are plenty of things you could do for very little money or free to get better pics. Here's a good video to give you some pointers, notice he takes a really good quality photo at the end with his iphone. I hope this helps.
