Not to derail the thread, but I'm honestly a bit shocked by the Sebenza's continued success. I find the small version clumsy at best, but I really like the large one... for a bunch of reasons that don't sell well from any other brand.
I like hydraulic, unflickable without modification action. I like the neutral handle shape and thinly hollow ground blade. I like the sandblasting that starts to wear immediately. All features that folks would bitch about on a new Reate or Benchmade model.
Why it continues to command the money that it does baffles me, but I like them. Why the BK2 was EVER a success is even more baffling.
Have you tried a buck sprint?
OP, The BK2, or similar, are odd knives to me. I like big choppers, but for the most part, unless designed with a full-height grind of some kind, 0.25" is generally too thick to add any utility other than weight. Dropping down to 0.2" is (pretty close to the 0.188" of other beckers) a 20% decrease and no lose an all gain in functionality, unless you're trying to make a short knife a chopper, such as the BK2. I think in every way, the BK7 or BK9 is better. I've not had a BK10 but have had similar and they're pretty decent with the tall blade and thinner blade stock. You would still be pretty hard pressed to break on of the thinner blades with hard use so the BK2, to me, goes to the point of unbreakable and then beyond. I don't think a knife is a good prybar, ever, as it lacks the primary component of a prybar, length for leverage. Yes, it can make a bad prybar and be used as such, but you probably still need some cheater pipe to get leverage to make it useful.
I understand why people like it, but for me and my uses, it's completely overkill. Something like an esee 6 is far better and still pretty dang hard to break. Maybe the BK2 with a Full-height grind would be better? Or a full height convex like the CS trailmaster. TBH, the trailmaster surprised me on how well it slices, considering it's thickness. It's a bit of an odd knife overall, for me, but it made it interesting on how you can get a beefy blade that still cuts pretty well.
I suppose a BK2 is better than a lot of other knives, but there are too many other knives that are better to bother with the BK2, even within the Becker line, to bother with one. I've tried the short thick knife thing before in some Busse & kin knives and they never stuck around long... they weren't great at being a knife.
I had a maker from the forums design something specific for this type of use though, and I love it. 4.2mm V4E steel with a little bit of BK4 type of angles mixed in. I think it works a lot better for me. Yes, I'm showing it off a bit because I love the design, but I my main point is there are better options than the BK2 at similar price points (this one was way over the BK2 pricepoint).
Edit: again, if it works for you, great. It seems like needlessly thick to me, based on my experiences and uses.
Unless you've miraculously become younger or at least stronger and more vigorous , I doubt your supply of energy has increased . I know mine hasn't !
