I get by pretty well with a SAK when I spread the peanut butter from an MRE onto a cracker or bread.
You aren't alone.
I've been backpacking regularly and seriously since about 1980. Over the years, I can't recall a single backpacking store that didn't or doesn't carry SAKs. They're still there very solidly, but now they're side by side with a selection of multi-tools, almost always Leatherman, and occasionally Gerber. As much as I love Buck, I don't think they have a realistic shot of displacing SAKs or Leathermans.
But, I've noticed a big change in the past 10 years or so - single blade locking folders!
Most backpacking stores have 2 knife displays. The first is a set of plastic wrapped knives hanging from a display prices typically ranging for $25 to $50 (with the exception of the big Leathermen). The second is a glass display which usually holds more expensive or bigger knives. In years past, this display case would hold the more expensive 50 tool monstrosities that Victorinox makes and a huge selection of multi-tools). In more recent years, these glass cases tend to carry more mid range locking folders with names like Cold Steel, CRKT and Benchmade. It's also much more common to see the Victorinox Trekkers, which have longer locking blades and have been around for a very long time but were rarely seen in backpacking stores in years past. And now, Gerber is making a big splash with the Bear Grylis line of knives.
My conclusion is that backpackers are more willing to go with a locking folder with blades in the 2.75" to 4" range (perhaps backed up by a small SAK or multi-tool).
So, where is Buck, the company that legitimized the locking folder?
Eastern Mountain Sports is something like the REI of the north-east. They carry a small number of Bucks, including the Buck X-tract (good move imo) and the Ecolite 112. The Ecolite 112 is priced just right and looks beautiful in the case. IMO, it holds it's own against any other knife one is likely to find in stores like this. More to the point, it has the look and feel of a substantial quality knife in way that the Buck Bantams and Bucklite Max lines just don't have (they're lower price point knives, so that's expected).
But, from what I can tell talking to the staff in these stores, the Ecolite 112 doesn't sell well. It is the *ONLY* knife there with a hunting style clip point.
It's just amazing to me. The Victorinox SAK and Leatherman have, rightfully so, become icons. The Buck 110/112 is also an icon. And judging from the lack of selection, Buck can't figure out how to sell that icon to the backpacking and climbing crowd. IMO, they should produce the Ecolite 110/112 drop-point. And they should call it that.
