Its tough...
Any collection suffers from the constant feeling of incompleteness. There's always something else you want.
Try to focus on using, sharpening and learning about your new knife instead of looking for the next thing to buy. You'll be a lot happier with what you have when you learn to slow down and enjoy what's in front of you.
I always think the next one is the right one, but then I see something else.
I have been using but get them sharpened professionally, I really want to learn how and get the equipment to do so.
