My two favorite knives are the SR M6 and the SYKCO S6. Two of the best, toughest and coolest 6" knives ever made.
I love the weight and res C grip S6.
The M6 is almost the perfect knife for me. SR101 differentially heat treated is my favorite. I can put a hair whittling edge on it and stays that way for quite a while. My only real gripe is the weight. I call it a tie between the grip comfort of the M6 and S6. The 3-4 ounces makes between that M6 and S6 can make a big difference when you have it on your belt all day.
I like timelord79's idea of the protruding tang and it gave me the idea for my perfect knife. Not for a glass breaker though. A while back I read a post that someone used their Cold Steel tanto to start a split in logs by hammering it tip first into middle of the log with a baton. I am sure it is not advised but the M6 excels at this task. I have never tried it with my S6 because I dont want to jack up the res C. But! If the S6 had a protruding tang I would not hesitate to try it.
My knife idea is a SYKCO Mutt 6 and SYKCO Mutt 6 Double Cut LE:
Mutt 6 CG -Blade- Differentially heat treated SR101 .24 thick, saber grind M6 style blade, with a swedge like the one on the Dogfather (available in tanker, black and green). -Grip- respirene C(S6/Dogfather type), slightly protruding tang approximately 1/4 (Same width and thickness as the tang, square w/rounded corners)
Mutt 6 Double Cut LE -Blade- Differentially heat treated SR101 .25 thick, full flat grind M6 style blade, no/swedge. -Grip- respirene C(S6/Dogfather type), slightly protruding tang approximately 1/4 (Same width and thickness as the tang, square w/rounded corners)
The SYKCO Mutt 6. A true mutt!
If I win can I have a Mutt 6 CG tanker and a Mutt 6 Double Cut LE?
