Question: How long is the blade
Document: There is a plastic sheath inside the nylon which actually contains the knife and protects the nylon from getting cut by the blade. This inner plastic sheath actually fell apart because it is held together by a strip of foam and glue which could not handle being beat up by the long hikes. I can reglue it with a stronger glue and it should be fine.Like the other M-techs I own, this knife comes sharp, but does not hold an edge well at all.
I got this for myself as I like long blades when I'm out camping so I can tackle any chore that pops up. We decided to rough it and build lean-to shelters. I have an MTech hand axe, but wanted to see what I could do with this. After about 2 hours of grueling hard work (about 45 minutes of labor and an hour of drinking cold ones), it was up and wind/water proof.
This is an awesome blade in my opinion. Not very sharpout of the box but that's nothing that can't be fixed.
allot larger than I thought. I also thought it was a folding blade, it was a gift and my son loved it.
this knife exceeded my expectations came with a good utility edge  good scales nice sturdy blade and a great sheath thanks
Very well built sheath to accomadate the large size knife.with built in pocket for smaller knife or blade sharpener you could take on just about anything.thanks for the good buy
This MTECH USA XTREME Mx-8062Bk Fixed blade was purchased to replace my field knife. The only draw back is the blade is not razor sharp but will cut with the proper amount of force. With that being said i love the look of this blade
The blade is great its heavy and solid. Has a great edge and good design. The sheathe however started coming apart as soon as i touched it. If the sheathe was a solid one instead of a cheap cloth one they could charge double.
Full tang....check! Solid construction......check! Thick blade......check! Sheath.......Not too shabby! Overall, a good knife. The saw tooths are not what I would consider actually usable so it fails there. However, for the price this is a real bargin!
Wow.! I love everything about this knife. In my opinion its worth 3 or 4 times what i paid. I own several knives and this is the one that fits best in my hand. Love the weight, balance and thickness of the blade. Strong ,sharp and beautiful design. You can not go wrong with this knife.
Answer: yes
