The OP said he's looking for 1-1.5 inch blade. And not for fighting bears.
Swiss Army Classic.
Okay, he also said Titanium and long handle, but I'd argue with only a 1.4 inch blade, you don't need any more handle. I never have. And what is the magic of titanium? Stainless steel is also rustproof.
21 grams is less than 100-120 grams for a long fixed blade (and sometimes those weights don't include the needed sheath).
And a Classic has a nail file, tweezers, and scissors (really handy for repairing gear, trimming moleskin, finger- and toe-nails, nose hairs after a month out, etc).
I can make a fuzz stick with it, get into a vac-pack bag, cut cordage, and make minor kindling.
If you have a wood-buring stove, ignore this idea - you need something bigger.
If you don't and can't find one for $6, PM me, I buy lots of 6 at a time from TSA seizures.
