Wow, some great responses. I've kinda crunched some numbers, and have come up with a few favorites so far.
The top spot for a specifically named knife is the Buck 110. Have had the same number of votes for a SAK not specified. But if we add in 4 specific votes for a Vic Soldier, 3 Vic Classic's, 1 Vic Hiker, and 1 Vic Pioneer, the SAK is the overwhelming favorite.
The third favorite is for a Generic Stockman pattern. There were some specific Stockman makers mentioned that were not included in this total.
Next were a generic Trapper/Mini Trapper/Wharnie Trapper, followed by a Peanut, with the majority being Case.
This has been fun, and I hope you will continue to add your "Top 5". There were a few surprises here for me, and I am happy to say I have many that are listed here. Like Elliott said, It will probably change. I know my taste in knives is constantly changing, sometimes as quick as a few hours, so I expect (meaning I would like) this to be an ongoing thread, but realize that probably won't happen.
