The Ultratech Gen IV. Double Edge (D/E). Yellow handle. Asheville built.

The Microtech Ultratech is the benchmark OTF automatic. The Gen IV is the most refined version of a platform that has been in continuous production since 1999. This version runs the Double Edge (D/E) profile with a Tactical Black finish on M390MK blade steel, paired with a yellow 6061-T6 aluminum handle. The Crud Kutter milled switch platform breaks up debris and reduces friction for more reliable deployment. The Dual-Fuel Drive Train produces the smoothest Ultratech action Microtech has ever shipped. Milled titanium pocket clip with ceramic balls, stainless glass breaker, stainless Torx hardware. Made in Asheville, North Carolina.

Note from Lone Star Knife & Supply: The D/E Ultratech in yellow with tactical black blade is a clean combination. The symmetrical dagger profile is the defining character of the D/E and the black blade against the yellow handle is a sharp contrast. Gen IV action. Asheville made.

LOVE THEM!!
Size: Small, Color: (001) Black / Black / Castlerock
LOVE! These socks are so comfortable! I wear a 5 in women's and a 3 in big kid shoes. The small fit me perfectly. I see where some say they run small but I can't say that was an issue for me. They are "snug" but thats what you want with a no show sock. I feel they have support vs the ones i used to buy at Walmart. They are very soft! I am actually buying more today and throwing my other ones in the trash!

So will not write down your foot
Size: Medium, Color: (001) Black / Black / Castlerock
I love these socks. They have a little bit of gel on the top of the heel for support in your tennis shoes and so your socks don’t write down. Very good quality.

Comfy and Stay Put
Size: Medium, Color: (002) Black / Black / Halo Gray
These socks are honestly great. They’re super thin and light, so once you have them on, you kind of forget they’re even there. No bulky feeling in your shoes at all. The best part is they actually stay on. I hate no-show socks that slide down after five minutes, and these don’t do that. The little grip on the heel really works, so you’re not constantly adjusting them all day. They’re breathable too, which is nice if your feet run warm. They dry fast and don’t get that gross sweaty feeling. And there’s no annoying seam on the toe, so nothing rubs or feels uncomfortable. Basically, they’re just comfy, stay put, and don’t cause problems — which is all I want from socks.
