How many different versions of the Dumpster Mutt are there?
Andy? Cold One? Jim?
I know that there are more than just the DMCG and the DM Double Cut finish.
If I remember correctly, these are the versions I know of:
DMCG (combat grade)
DMLE (full flat grind and satin finish)
DMDC (dual cut)
A military over-run that was nearly completely serrated, full-flat ground, and satin finished
Dual cut styles with various color coatings and I think black or tan handle options.
As far as I know, that's all of them.
