It definitely competes with Microtech! It has a mirror polished edge and a strong spring yet it still sports an easy tension thumb button. Lightweight and fast deployment. Deep carry clip too!

The Hogue H&K Hadron is a great EDC

Bought this knife about four years ago from the Blade HQ Utah store in person. (Please get the store back open) I miss being able to go to the store. What an experience. Like I said I’ve carried this knife every day for four years, and it’s used daily. I work out in the West Desert and if your familiar with the area you know how dusty it can be. Poof dust gets everywhere. I never had a misfire, and the knife has kept its edge. Recently however the knife locked up and would not budge. I contacted Hogue, snd they could not have been more helpful. They had me take it to a dealer (my choice) as they stated their policy is to not mail automatic knives directly to or from the customer. Mandy at Hogue was awesome. They had the knife for about three weeks and mailed it back to the dealer. All at no cost btw. My knife came back sharpened and operating like new. For the price, this knife cannot be beaten. I highly recommend it if you’re looking for a great OTF. I went with the clip point because at the time I’d never owned a dagger-style blade. I’ve since bought a Benchmade Infidel and love it. I will say the thumb action on the spine makes it a real ambidextrous OTF, my Infidel with the action on the side took some getting used to. The size snd weight are great for EDC it’s a decently balanced knife has ridges for gripping the knife. For the money you cannot go wrong, the warranty and customer service at Blade HQ and Hogue make it a no-brainer. I love my Benchmade Infidel and my wife’s Auto ADAMAS, but the Hadron holds its own as an EDC. Hope this review helps.
