Hi Dino.., and welcome to the Bali-Forum!

You've already heard from some very knowledgeable people..., and like many domains.., some of "worth" comes down to function.., and some simply to subjectivity and taste.
From my perspective, the price of the Tachyon is not-to-shabby considering the R&D invested.., but Chuck has a valid point for sure!
I must also admit that the Tachyon actually
shocked me personally, because I didn't expect to like it so much because of it's smaller size in comparison to the older traditional models I like. I have now flipped a couple for a few weeks and have
eaten my previous thoughts! It's one hell of a knife!
I suppose we get down to the definition of "worth".., and the BM's are all very good knives..., supported by a company second only to my brother's in "Customer Support" (heck he's my brother)...lol???
For the average person.., that in my opinion isn't really beating up on knives daily.., there probably isn't any Balisong worth twice as much as a Benchmade (for cutting use)?? They will certainly handle the general cutting needs of almost anything you would use this style of knife for. Having the "worth" thing done with

..., many of us in here have paid 20 times the cost of a 40-Series BM (and more).., for knives we want for our collections. Will they cut more efficiently than a new Benchmade Model?? Maybe??.. and certainly different blade styles in customs will do a better job when task specificity becomes part of the equation. Will they cut
twice as well???....I doubt it.
Those knives are more like investments.., and have done very well relative to putting 20K into a low-to-mid-risk market fund over the past few decades.
Boy talk about tangentially getting off topic...lol...(I have a fever and the Flu...sorry)
Anyway.., sure the Tachyon is worth $200 bucks.., cause we all have 'em and didn't blink. I also did write Mike and sing my praises for the knife.., since I was skeptical, and the question of
"worth" shows up so much on every Forum location.., about all sorts of "this-vs-that".., I truly believe the buyers establish the worth more than the actual form and function of the knife.
For an EDC.., I do like the 440C (or 12C27 on the first 42's), better than 154 CM if I'm going to roam around for a few days in the mountains. I can return a good edge to it easily with a pocket stone in a couple minutes.., and although I know a couple of guys that can do that with 154 CM.., the designer steels take me a bit longer.
Now that I've blown this thread all over the map..lol..and convoluted the issue beyond hope of recovery.., I would say to over-extend a charge card and get both. We all do that.., and enjoy the company of others that want every
Lazer-Bat-Blade available.
Sometimes I actually write..., "Hope this helped".., but no use in this case!!
Come on back and visit!!..., and have a neat Holiday Season!
