Welcome Woady. It's more than an addiction, it's a support group <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />
The 12 steps of recovery:
1) Admit you have a problem (in this case, not enough knives)
2) Admit that you can't overcome it on your own (that's why the store is here <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" /> )
3) Decide which blades you can't live without
4) Make a written list of all the blades you need
5) Spend hundreds of hours on the exchange looking for your grail
6) Buy several knives in the meantime
7) Hit "refresh" every five minutes on the forum to ensure you didn't miss the "go" command
8) Order three of everything released at the Yard
9) Watch in awe as your credit card statement magically grows
10) Cry a little
11) Abuse the knives when they arrive
12) Repeat
