Kershaw Scrambler,

(I actually just recently did a review on one I received a couple weeks ago, you can find it using the search bar)
It's only 0.1" shorter in the handle, and 0.5oz lighter in weight, but still a very robust 5.2oz. With a 3.5" blade like the lifter, And the g10 scale will give you much better grip if using it to whittle.
Also, the tanto tip isn't the biggest issue I see with the lifter, but rather the recurved blade isn't ideal for whittling, nor is that cheap soft "axe" steel that it's made from: 3cr13... You'd need to spend a lot of time resharpening that edge if using it primarily on cutting wood, as the low carbon content is not suited for holding an edge against a strong wind gust, let alone wood cutting.
The Scrambler fixes both those issues with a classic drop point blade, with that continuous straight edge for longer sliced cuts, (still enough tip for finer digging), and they a good job with their 8cr13mov, which will hold an edge exceptionally longer then 3cr13 (with at a minimum twice the carbon content + trace amounts of molybednum and vanadium not present in 3cr).
So its an all around better knife; blade steel, blade profile, g10 scale, (reversible clip for LH carry): but in a very similar designed package; grip ergos, weight, framelock, speedsafe assist, flipper, etc. Only thing it doesn't have is the deep pocket clip, but you can get one if its that big if an issue, plus it comes with a nice little nylon belt sheath.
If you're looking for a knife that "feels" a lot like the lifter in your hand, but is better for whittling, (bettet all around by a big margin), and is still affordable, Scrambler is hands down my suggestion. It's a little more expensive, but hardly bank breaking at around $35...
