Question: how durable is the sheath to this knife.
Document: The knife is great! lightweight,durable, feels good in the hand, sheath fits nice, and came sharp from the packaging! The sheath holds the knife tightly and doesnt let it rattle around.
I got this knife a few months back and i have to say it is hands down, the best knife i have ever purchased. The sheath is Very durable and can be adjusted easly and quickly. I have recommended it to several coworkers and recommend it to anyone else that is looking for a fixed blade worth of hard work.
This is a very good knife, especially for the money. The blade is a great length, with a comfortable choil and jimping. The knife is durable and performs a variety of fine detail tasks well. The sheath is the rockstar of this package. The friction lock holds the knife tightly, and the sheath is designed as adjustable to horizontal or inverted carry if desired.
This knife is simply awesome. You can just feel how strong and durable it is. The sheath is very nice too. I like the fact that the knife locks into place. It does take a little effort to pull out but nothing anyone cant handle. I also like the 4 hole on the handle of the knife it comes in handy in case you want to make a spear out of it. I'll probably just change the orange paracord its a little conspicuous.
Cheap, durable and holds an edge. Bought to throw in my hunting pack and have used it for everything. Paracord came off immediately, replaced with black cord. Flipped the sheath so the letters wouldn't show.
I usually don't like wrapped grips on knives, but this fixed blade looked so cool I had to get it. The cord wrapped grip is done very tight and nice. It feels good in the hand either standard or reverse grip. The blade is nice and thick and seems very durable, fairly sharp as well. The sheath is better than I expected. The blade locks in tightly and has a multi-directional belt mount so you can wear it any way you like. Very satisfied with this purchase.
Knife came sharp, steel seems to be durable. Will have to see how the paracord wrap stands up to use.
Its about the middle between chopping and slicing angle wise. The knife sharpened great and after i used a stropp on it it was almost a razor. You dont need some fancy sharpener although i use a Buck fine diamond stone. Overall for what you pay this is what you get. Nothing less nothing more. If you want a tough sharp and durable knife buy a KABAR. I consider this a beat up knife and i have not snapped any of it off so i consider this a tough knife to a point.
It's everything it was said to be. It's sharp, durable, easy to throw and i can't wait to unwrap the paracord and make me a spear..
I used it to open up and fillet fish twice and worked perfect. The orange power cord does absorb moisture so keep that in mind when cutting fish or any other animals. The loopholes on the knife make it easily attachable for makeshift spear making, which I did try but did not use it for anything.Overall it's a great knife especially for ankle access. I love Gerber gear (but not a bear grylls fan). The knife is great for multiple functions and is highly durable.
