Guys...don't get too wrapped up in this. Dan doesn't publish this lightly:
http://www.scrapyardknives.com/guar.htm Our guarantee is simple. We warrant your knife against any and all unintentional MAJOR damage for life. The Scrap Yard guarantee is on the knife and NOT just for the original owner.
There is nothing here regarding only applies to special knives, etc. Dan wouldn't sell a knife if it didn't fit his own expectations. The key for me defining "unintentional". I don't personally expect the Scrap Max to be a prybar.
Also, let us not forget that hardness values hardly tell the whole story...there is much more to materials science than a simple RC.
