Welcome to Bladeforums Jamie321.
Lots of good advice has already been given. I just wanted to add, in reference to judging knives by there price, that there are vendors out there who will sell cheap Pakistani knives at ridiculously high prices (hundreds of dollars) and call them "custom" or "handmade". Sometimes they buy just the blades and put the handles on them themselves. Sometimes they include a very nice looking sheath as well. But whatever they call them, or whatever they look like, the knives are still crap. We've had some unfortunate individuals come here, post pictures of the "Damascus" knives they purchased for hundreds of dollars, only to find out what they bought was a cheap Pakistani knife that could have been purchased elsewhere for a fraction of the price.
And so, my advice is to not judge a knife by it's price, high or low. Don't assume that because a knife is expensive that it is a quality knife. That can be a good way to get burned. Instead, judge a knife buy who made it, and by who sells it. And when in doubt, ask here on Bladeforums, there is a lot of collective knowledge here, with a lot of people who are happy to help with no judgement or ridicule whatsoever.
Another piece of advice, don't judge a knife by how it looks. There is an abundance of knives out there that look good, but are in fact made out of crappy steel of unknown origin, and with either a lousy heat treat, or no heat treat. So like I said, when in doubt, ask here.
Good luck in your search.
