Good luck! Collecting SAKs can become very addicting. I've recently been bitten by the SAK bug myself. I have switch my main focus on knives from traditional pocket folders to swiss army knives. As users they are great, and as collectibles, the choices are endless. From the early vintage models to the modern limited edition Alox runs, Saks can be highly collectable. I believe Victorinox is now catching on to the current collector knife markets, and I predict/hope they will be releasing more limited edition runs more often in the near future. The great thing about collecting SAKs is that they can be much more affordable to collect than a lot of other brands. Although generally priced competitively, you can still pay a hefty amount for collectible SAKs such as with the Scientist, the limited Alox editions, and the older vintage hard to find models. My favorite SAKs are the Alox Pioneer/Soldier, the Alox Cadet, and the Explorer. I also really like the Climber, and the Spartan.
