Keep an eye on busseknives.com – along with Busse, it also has Scrap Yard and Swamp Rat knives (look at "Shop Now"/"Shop Knives" under each brand for models currently available). Also watch this forum for "Ganza" sale announcements (hint: the knives usually are limited in number and sell very quickly, so be ready to send your buy request email literally the second they go on sale). The O2W sales feature new models that are not so limited in number, but they still sell out in a few days at most.
For smaller knives, you might want to consider the Anniversary Mean Street (AMS), Cultellus, and Steak Knife (3.5" version). You are most likely to find the AMS available before the other two. Highlights:
- AMS - .155" thick INFI, full height flat ground blade
- Cultellus - .125" thick INFI, full height flat ground blade
- Steak Knife - .090" thick Elmax steel, hollow ground – it is one heck of a slicer!
All 3 are real close to the same size, with about a 3.5" blade length. Attached are 2 photos (neither photo is mine, I likely saved them from BF).
For out-of-production models, the "Busse / Swamp Rat / Scrapyard Knives For Sale" BF forum (also referred to as the Exchange) is generally the best place to find them. You might also find some on eBay, BUT BEWARE OF SCALPERS AND FAKE BUSSE KNIVES ON EBAY! Even on the Exchange, know what is a fair price before saying "I'll take it". Enjoy the hunt!
