In the same size range as the 110 but at a fraction of the weight, consider a Spyderco Endura lightweight.
I have a plain-edge Endura - what a great knife! Great for camping, hiking, defense/peace of mind, simple utility, etc. Im kind of a traditionalist at heart, so for me the benchmark of quality, affordability (which is important to me), and ruggedness, has always been the venerable Buck 110. That knife is a rock and certainly has been carried for work/hunting/hiking/combat, etc. as much or more than any folder. In other words, lads, I like it. HOWEVER, once you hold an Endura, theres no looking back. The Endura weighs a scant 2.9 oz., the 110 weighs a whopping 8. The Endura's blade is 3 and 15/16", while the 110's is 3 and 12/16". I can carry the Endura down in my pocket, in a sheath or, naturally, clipped anywhere I can think of (jeans pocket, shirt pocket, waist band, on my pack-strap, on my truck's sunshade, on my boot, etc.). With the 110, I can lug it around in a belt sheath or in my pocket, but Id better cinch up the old belt extra tight, 'cause those are 8 heavy ounces of knife. The Endura comes in ATS-55 steel, while to get top-of-the-line steel on a 110, you have to go the more-expensive Pete's Custom Shop route. And the Endura passes one of my most-important tests for a camping/hiking blade: Can it spread peanut butter easily?
