I've had my heart set on a Ratweiler or an M7 for quite a while because of Swamp Rat's reputation, but just checked out the Scrapyard website. Both sites seem to offer the same guarantee, but Scrapyard is selling their Scrapper 6 for $80 less than the M6. Sure it's different steel, but other than that, what's the difference? I don't particularly want to spend $180 on a knife, but I'm having trouble trusting Scrapyard at that price. Any info would be welcome.
