Well, the grind is kind of steep.
Both knives are similar, in that the primary cutting edge tapers from just above the center line. It looks neat, and probably adds some strength, but it makes for a more abrupt angle than, say, the 26.
It hasn't made much difference in actual working with the knives, but I notice that a high, flat grind slices easier than the grind on the #1 and #5.
For what it's worth, I prefer the 6" on my #5 to the 5" blade on my #1 for balance and handling.
That said, I've never found either to be lacking. The #1 did just fine dressing a whitetail (although I had to be careful with the back edge) and the #5 has been pretty good as a camp knife. A little light for chopping, but a nice compromise knife. Does everything pretty well.
