Ultratech Gen IV – The Next Evolution in OTF Innovation

The Ultratech Gen IV represents a thoughtful step forward in Microtech’s iconic line of OTFs. Unlike previous generations, Gen IV ditches the Zero Blade Play (ZBP) system entirely—returning to a more traditional precision fit and finish while leaning on feedback from the Microtech community. 

This D/E version features a 3.5″ Bohler M390MK double-edge dagger blade in a stonewash finish, paired with a bold blue anodized aluminum handle. Deployment is fully automatic, and the design includes a glass breaker and pocket clip for daily versatility.


Note from Lone Star Knife & Supply

This is where Microtech has dialed back a few “bells and whistles” to focus on performance you feel. The action feels smooth, solid, and familiar—but updated. The blue handle with stonewash blade gives it visual pop while staying grounded in usable design.

A much more affordable option for Subaru owners
Size: 5 Quart, Style: 1 Pack
When you're paying between $16 & $18+ per quart of Subaru brand CVTF 2 fluid this is a much more affordable option. If you look on the back of a Subaru branded CVTF 2 quart bottle you'll see the Idemitsu logo. Doing this job myself saved me over $1000 on what the dealership quoted me to change the valve body and drain and fill my CVT without skimping on anything.

Same fluid as the Subaru brand
Size: 5 Quart, Style: 1 Pack
This is the manufacturer that makes the Subaru cvt fluid. I used this for the drain and fill on a 2019 Subaru Forester. No problem using a hand pump to fill the transmission. Excellent product will use again to service a 2018 Subaru Crosstrek.
