I disagree to the advice of pulling out of the hobby if you still can. This hobby actually does not cost much of your fortune. Plus, if you are not happy with a knife or lose your interest in it over time, you can usually get back at least 60% of what you paid for (unless you seriously used/abused it). Think about other hobbies like drinking, eating, touring, shooting guns, clothes, etc. Most often the money you spent on them is (almost) completely gone.
My advice is: pace your knife purchases properly and give enough time to enjoy every knife you acquired.
