I've only got the original mutt, but I can tell you anyone I've showed it to cannot believe how tough it is.
Can't wait until my YKCG arrives.
I don't have the largest collection of knives but I tell anyone who cares to hear it.
SYKC offer the best value for dollar out there
I've carried an old Marbles woodcraft knife since I was 14 or so for bushcraft, I think the YKCG may replace it.
