The bottom one seems to be Scrapper 6 like.
I just looked at Shaolin's post about his Scrapper 6 and compairing the blade profile to the Scrapper 6 in his pic, it is almost dead on. The bottom of the choil is Dumpster Mutt profile but the blade does look close to the Scrapper 6.
Is it possible that a Scrapper 6 got profiled and fitted to the Double Cut Dumpster Mutt specs?
This is cool.
