Buck has offered this type knife many times. Even currently, in their Bucklite, Selector and Bucklite Max. Have you searched Buck's website? DM
What David said plus the discontinued Paperstone versons. You don't discontinue products that sell well.
The Bucklite, Ecolite and Bucklite Max all have decent qualities and are/were OK knives. But none of them combine the qualities that I think people are asking for.
What I'm hearing repeatedly in these threads is that people are asking for thinner, lighter and more pocketable knives that I unmistakenly look like a 110/112.
The Bucklite and Ecolite were both light, but they were both too fat to be comfortably pocket carried.
The Bucklite Max is nice and thin and carries nicely, but it doesn't look like a 110.
Nobody wants to see any change to the classic 110/112. But there have been all sorts of 110 variations. I think 2 would sell well.
A thin linerless G10 scaled 110 with a thinner handle, thumbstuds and a clip. Essentially, a Bucklite Max with upgraded scales and that looks like a 110, and not a Bucklite Max.
A thin Ecolite with a thinner handle that looks more beautiful than the old one.
I had an Ecolite. It was nice in many aspects but I understand why it needed some tweaks to sell better. First, it would have been a decent work knife if it had held up better. But more importantly, it wasn't compellingly beautiful like the original 110 is and IMO, it could have been. Nicer pivot washer, full brass liners, no ugly finger scallops. And it needed to be pocket carry thin.
