I have a three teir system. First is the general folder, where I calculate the cost of my upcoming shipments. This folder also contains lists of all the fixed and folding knives I would ever consider buying.
Then there is the folder with all the knives I would like to buy (many of them still in pre-production), and contains my top ten, top twenty, and miscalanious lists. As knives attract interest, they move around from "misk" to one of the higher priority folders, and eventually into calculations for purchase.
I don't think you want to see my whole list...
I like to be organized, but excess free time helps too.
Ohh, almost forgot. Here's my top ten.
1. Ka-Bar Becker 9
2. Spyderco Bali-Yo (ok, it's not a knife but it's on the list.)
3. Buck Bravo
4. Kershaw Lahar
5,6,7. All three variations of the Kershaw Groove (once they are available in 14C28N)
8. Spyderco Police 3
9. Kershaw ZT0500
10. Kershaw Composit Leek
