Since this short little comparison has stirred up a bit of controversy about SR101 (thanks Bruce), I am bumping it to the top so folks can see exactly what I did and draw their own conclusions. The manufacturers themselves perform much more scientific tests on their steels than I could ever do. How many of you cut a hemp rope thousands of times to see how long it takes to dull an edge? I never said SR77 had equal edge retention to SR101. I did say that most users probably wouldn't notice the difference. That is opinion, not fact. The SR101 blade that I use the most is my Ratweiler. It's edge holding is amazing, and yes, a little better than the SR77 Dog Father. So what? They are both great steels and great knives.
