The latest generation of the Tachyon butterfly knife, the production Microtech Tachyon III, distinguishes itself from previous models with milled, single-piece channel construction handles, a spring latch, and a standard pocket clip. The blade showcases a non-sharpened swedge-ground tip and milled grooves with the Microtech logo, production date, and blade steel markings up front.

What would a brilliant design be without that smooth action you crave? The Tachyon III exceeds all expectations with an advanced ceramic ball-bearing pivot assembly that eliminates handle play and produces first-class flipping dynamics. The pivots utilize Viton o-rings for load dampening, and heat treated stainless steel retainer plates ensure long-lasting performance.

This Tachyon III model has a Apocalyptic finished ELMAX steel clip point blade and durable type III black anodized handles. Includes adjustment tool.

Exactly what I hoped for.

Great Bali.
If you're wondering how the aluminum feels, it's pretty much the same as any aluminum MT OTF. I'll definitely get the Apocalyptic Serrated version if it ever comes back. Thank you once again Microtech and BHQ!
Love this knife

Love this knife a lot. Thought I was gonna be disappointed but I was proven wrong. It flips really nice and feels great in hand, should have bought two.

I had reservations about purchasing this knife. I own a Tach 3 with Titanium handles and I've been waiting for the production run to buy another. I was extremely disappointed once I found out that the production run would have aluminum handles (especially considering the price). IMO a knife made with aluminum handles should never be this expensive. Please be aware that the rating and review I'm giving doesn't have price factored in to it.

Anyway, I reluctantly decided to purchase this knife with the thought that I would just return it and get a Ti handled version if I didn't like this one. To be honest, I was pleasantly surprised with this knife. This one flips extremely "fast" should you choose to do so. Balance is extremely good IMO (however flippers vary on what the balance of a knife should be for their flipping style). There is almost zero blade wiggle or handle play. I have many different bali's in a wide range of price points and they all have there own unique quality and this one is definitely a home run in a wide variety of characteristics that a bali should have (price not considered). This knife is a tad light however, heavier than a 51 and larger. This knife will be staying in my collection, the more I flip it, the more I like it.

If you are on a budget and were planning on buying a 51, I would say wait and save up an extra $55 for this one. This flips, hands down, 10 times better than a 51. You won't be disappointed.

I've only been flipping this knife for about 2 hours now so I can't speak of the durability. I really don't know how the aluminium handles and the black anodizing will hold up over time. I really don't care about the ano not holding up because I'm planning on changing the color scheme anyway. I mod every knife I own to "make them mine". I just hope that the aluminium handles hold up, time will tell.
