Newbie here. I got a Lachesis (middle size folder) for about $50 off list, which is still a spendy knife. I used it for a couple weeks, and it cut fine, felt fine in the hand. Sorry, but I have no paper/rope/car door cutting reports.
To be honest, I was more turned off by the looks, the micarta looked kind of lame. So I had Rainy Vallotton redo it with bone scales and he rainbowed the Ti bolsters. Man, is it a looker now! I will post some pics tomorrow.
I like it fine. I've cut veg, cut branches, opened mail/boxes/etc, and done some light carving with it, and it works great. I can see where if you were really working it hard, and maybe had fluids involved, the handle (back end) might slide around in your grip. Anyway, I hear that was the main reason for the Chili Pepper handle on the fixed blades, better grip.
Just my $0.02. Different strokes for different folks. BTW, I dig the Striders, the MTs, the Daltons, never too many, I say.
