Scrap Yard & Swamp Rat here.
I only own SR77 and SR101, but would buy Scrap Yard INFI.
Busse Combat products are great, but I've tested a few of a my SYKCO & SRKW knives well beyond anything I would ever expect from them in the field and outside of some finish wear....they're as good as new. Therefore, I just don't have a reason to buy anything else.
The SRKW products I own are: Chopweilers, RMDs, Rodent Solutions and Wardens. If the Scrapivore would have been available when I was buying my Wardens I would have went with the better priced SYKCO product. My Chopwielers and RatManDus are my "go to" knives though. I very highly doubt they will ever be replaced.
My favorite knives are:
Small = Scrapivore or Warden
Medium = Scrapper5 or RMD
Medium Large = Chopweiler
Large = Dog Father
The only Busse product that has REALLY interested me is the recently released Basic 4. I like the deep belly, and short blade ... just looks practical. I'm not completely satisfied with my Rodent Solutions, and am looking for a replacement. However, at those prices I'll wait to see what the SYKCO 411 looks like <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />
