Seems to be a copy of the Gerber Mark 1, one of the most copied fighting knives of all time. I have an original and have picked up a couple of REAL cheap, crappy copies over the years. Your M Tech looks to be a high-quality, modernized clone.
The original Gerbers came with a cool sheath that had a thumb-break strap and a nifty belt clip that worked GREAT with tall cowboy boots. Only drawback to this arrangement was that the very rough textured handle of the knife would rub against and irritate your calf, but you COULD get used to that. Yes, I speak from experience on that point. Wore mine that way quite a bit in the late '70s.

I bought one of those in a knife store in the Westroads shopping mall in Omaha in 1983. I carried it in my boots a couple of times but it was a real pain in the ass.
I'm very lucky that I did not get caught with that knife because I'm fairly certain it was illegal in Omaha.
My stupid roommate stole it from me in 1985 or 86 when I was living in Clearwater Florida. I was never able to find one to replace it. If I had the opportunity now I wouldn't waste my money.
Here's a little bit of open mouth insert foot for you.
In late 1990 my unit was getting ready to go to Desert Storm, actually
Desert Shield at the time. I decided I needed a good fighting knife to take with me. So I went down to a mall in Tacoma and I found a knife store.
I had a choice between a K-bar and this Gerber Mark II. I knew
nothing of knives at the time.
So I let the owner of the knife shop know that I was getting ready to go off and fight for my country and wanted to know which of the two he would recommend.
It turns out that the guy had fought in Korea and apparently his unit had been overrun by either North Koreans or Chicoms and he did, in fact, have to defend himself in a hand-to-hand knife fight with his USMC issued K-Bar. He explicitly told me that if he found himself in the same situation with only a Gerber Mark II he would consider himself to be unarmed.
I was still stupid and bought the Mark II.
Again, if I had it to do all over again I wouldn't have bought either the Mark I or the Mark II except
maybe as a novelty item
Right about the time that all the Covid insanity started I decided I needed to get serious about putting together an actual Get Home Bag. After doing some research I decided to the best combination of budget and utility for me would be a Gerber Strongarm.
