Back Door Entry. Still Dangerous.

 

This is a used Microtech Ultratech D/E Gen IV in Blue with a Stonewash Standard double edge blade. It is in great condition and fully functional, with strong deployment and solid lockup just as you’d expect from a Gen IV Ultratech.

The Ultratech is Microtech’s flagship OTF platform, and the Gen IV refinements continue to make it one of the most trusted out-the-front automatics on the market.

Why the Ultratech Still Leads

The Ultratech remains the benchmark for American-made OTF knives. The Gen IV platform refines ergonomics and internal geometry while maintaining the durability Microtech is known for.

The double edge blade provides symmetrical performance with a clean, aggressive profile, while the stonewash finish helps hide wear from use.

Blue anodized handles give this one a sharp, confident look without being over the top.

Why Used Still Matters

We don’t always get to choose products made in the USA. Most categories simply don’t offer that option anymore. Pocket knives are different. There is still a strong American manufacturing base building tools like this right here at home.

Whether new or used, supporting American knife makers helps ensure that continues.

If you’ve been looking for a clean Ultratech at a more accessible entry point, this is a strong one.

Pillow for everyone
Item Package Quantity: 2, Size: Queen
I think this pillow is too firm. I prefer a softer pillow but wanted to try this one. I may just have to get use to it. I will keep using it and see if I cannot get use to it.

Gonna get more for the guest room while I'm thinking about it.
Item Package Quantity: 4, Size: Queen
I will buy these again in a few years. I got 2 for me, and two for my man. They look super nice and full, and squish perfectly when you lay your head down on them. They are economical and priced nicely. They fluff decent when you fluff them, and I love my pillows again. These got rid of my headaches from neck trouble. I love these pillows. I'm gonna actually buy some right now for my guest room while I'm thinking about it. I compare these to that hotel I slept at once that had the most amazing pillows. Clean crisp fresh and soft. But not too soft. They are definitely soft, but cradle your head like a hug.

Well made and soft Resilient but not memory foam Good for back or tummy sleeper
Item Package Quantity: 4, Size: Queen
These pillows are well made I put them in the dryer on medium heat for 10 min 2 at a time, and they doubled in fluffiness They're soft to the touch as well as in plushness/depth They are resilient but not memory foam I don't think they would be firm enough for a side sleeper but nice for resting on your back or tummy

A product that will make a difference!
Color: White, Size: King (Pack of 2)
These king-size pillows are incredibly comfortable and supportive. They are soft enough to feel luxurious, yet they provide great support for my head and neck throughout the night. The king size is perfect for a larger bed and gives the bed a full, hotel-like appearance. The pillows keep their shape well and fluff up nicely after use. I've been sleeping much better since getting them and would definitely recommend them to anyone looking for quality, comfortable pillows.
