It is always interesting to me to read forums. Inevitably people will start to discuss interesting topics and for some reason the discussions always seem to drift farther and farther into dreamland and away from practicality and common sense.
I'll address a couple points I have seen in this topic;
Framelocks are not as strong as other locks: Lets inject some common sense here. How strong does a lock need to be? I'm nearly fifty and been using knives for a good 40 years now, only one lock has ever failed on me, liner lock in a buck crosslock when it first came out. I got a tiny cut. I would doubt that even one out of the people reading this could put anywhere near 100 foot pounds of torque on a knife. (think of lifting a 100 pound weight that is suspended on a foot long bar sticking out of the end of your hand. One hand. Over a hundred pound single wrist curl) If you are using a knife and you accidentally put pressure on the back of the blade it will probably be less than a pound max. If it is more, you honestly have no clue how to use a knife. If you are putting enough pressure to break a framelock that is securely in your hand, the pressure would surely be enough to remove your fingers. Get real.
Titanium is too hot/too cold : One person mentioned specific circumstances where that may actually be true, it doesn't hold true for most of us. I worked in an open to the air warehouse for the last 20 years and used a Ti handled knife since 2002. Temperatures ranged from 6 degrees F in the coldest nights to 100+ in the middle of August. I kept the knife in my pocket where it was always about the same as my body temp. I didn't lay it down in the sun, or leave it sitting out in the cold. I took it out of my pocket, used it, and put it back. (often many times a day) Winter I would often remove my gloves to use it. Never had a problem. Few people would even use a knife in the extremes that I did. Titanium is less thermally conductive than aluminum, steel, or brass. (How many millions of knives have been made with brass bolsters?) We take the knife from our pocket, (where it is about body temp.) cut something, and put it back. It's OK to dislike titanium, but try to be realistic.
Framelocks wear out Welcome to planet earth. Any moving thing wears. Do you honestly believe that other locks don't wear? Just because you can't see the engagement of other locks doesn't mean that they are immune to the laws of Physics. And just like the buck 110 that grandpa still uses to clean deer, Your framelock will slowly travel to the other side, but like grandpa, by the time you are 75 years old you'll understand that a knife with a tiny bit of almost imperceptible blade play will still be safe to use and clean a buck.
OK Rant off for the evening

Because we are using fixed blades, or slip joints???
