Ultratech Spartan Gen IV. Topographic Black Deep Engraved Handle. M390MK. Stonewash.

The Microtech Ultratech is the flagship of the OTF lineup, and the Spartan Gen IV brings a double-edge dagger blade profile to the platform's fourth generation. The Gen IV update introduces a new OTF drive system that Microtech describes as the smoothest they have ever produced, with the firing switch riding on a milled platform that breaks up pocket lint and debris and reduces friction for more consistent deployment over time. The handle is machined aluminum with a topographic pattern deep engraved into the surface. M390MK Spartan dagger blade in stonewash finish, 3.5" with a 3.2" cutting edge. Milled titanium pocket clip with a ceramic ball, stainless steel Torx hardware, and the new stainless steel glass breaker at the pommel. Dual-action OTF: thumb slide fires and retracts. 8.54" overall. Made in North Carolina. Limited lifetime warranty.


Note from Lone Star Knife & Supply: The Ultratech Spartan Gen IV in Topo Black is the flagship OTF in one of its more distinctive handle treatments. The deep engraved topographic pattern gives the aluminum handle texture and depth that a flat anodized finish doesn't have. M390MK dagger, Gen IV drive system, North Carolina made.

⭐️⭐️⭐️⭐️⭐️ Incredible Comfort – Like Sleeping in a Luxury Hotel Every Night!
I am beyond impressed with the DIORIS Pillows Queen Size Set of 2! From the moment I laid my head on them, I knew I had found my new favorite pillows. They strike the perfect balance between soft and supportive, making them ideal for back, stomach, and side sleepers like me and my partner. The fluffy down alternative fill feels just like the real thing—plush, breathable, and incredibly comfortable without triggering my allergies. These pillows don’t flatten out overnight either; they maintain their shape and bounce back beautifully each morning. What really stood out to me was the hotel-quality feel. The outer fabric is smooth, skin-friendly, and breathable, helping me stay cool and sweat-free throughout the night. I wake up feeling refreshed, well-rested, and with no neck pain—which is a huge win! If you're looking for affordable luxury, I highly recommend these DIORIS pillows. They’ve completely upgraded my sleep experience, and I’ll definitely be buying another set for the guest bedroom!

Helps you get a good night's rest
Color: Blue, Size: Queen Size Set of 2
These are my favorite pillows. I've had so much neck pain and headaches in the morning. This all stopped once I started using them. They hold up their shape and seem like they are good quality. My husband kept trying to steal my pillow, so I had to order him his own. You won't be disappointed in these pillows, and you'll get much better sleep.

Very soft!
Color: Blue, Size: Queen Size Set of 2
I like the softness of these pillows. They are too bulky for me but my husband loves his. I’ve been using a flat pillow for too long. I may just need to adjust to it.
