I usually buy a at least 2 knives and the most I bought was 5. I wish I bought 40 DFLE's instead of 4 though. I especially like being to trade because that is one way you can get knives on the secondary market for retail prices. When a good knife comes out buy a few and then trade for the ones you want and the mark up's cancel each other out. Of the 5 HCLE's I have kept one traded 2 and will probably sell a couple.
