I very rarely carry my Millie, so I can't really weigh in concerning tip strength. But in use I sure am worried about breaking it, unlike with my Enduras and Stretches .
I like the classy, clean looks of the Millie-blade, but aside of that I'd really want it to have a stouter tip. I don't see why a otherwise very sturdy knife with thick bladestock has such a delicate tip. So I'd like to see it beeing made stouter (like on the Endura) OR the whole bladestock to be thinner and slicier while keeping the current tip.
Same goes with the PM2, which I like very much more than the Millie; it's tip should be a tad stronger than the Millis due to the more obtuse angle, but still to fragile (or just fragile looking?!) for my taste.
Again, i think a thicker stock makes more sense when combined with a stouter tip, even in the PM2.
Top three going by pocket-time: Endura 4 in VG 10/Micarta-scales; Stretch 1 in VG 10; Endura 4 in HAP 40
