Question: What is the steel?
Document: i feel my cold steel safe maker II is the best emergency knife to carry. to each their own but i just thought i'd share my opinion that if your going to buy this knife then you should know that it is too thin and not sturdy enough to be used as a last ditch knife. i will say it is better than nothing and can serve a purpose.
Its cool, it locks in its sheath really really well. You can keep this pretty much anywhere. very very sharp, a little bit scary to hold because its so small and sharp but i guess thats the point. Cant go wrong with ka-bar either, if you need a small sharp deadly knife this is it, or the Cold Steel Urban pal
I've had this knife two days. It seems to be a good value. I'm not sure how good the steel is. I'm still figuring out the best way to hold it. It comes with a paracord necklace that I plan to replace with something else. The point is extremely sharp, and I imagine could do some soft tissue damage if the victim is not expecting it. It is extremely lightweight.
Its cheap so I don't hold it to high standards. It hurts your hands to do heavy cutting with it(duh its tiny). It isn't the greatest steel(duh its cheap). The sheath is pretty good and snug. Its easy to conceal for all the mall ninjas out there. I wouldn't rely on it to save my life. I'm sure I'll find something to use it for eventually. It's pretty decent for the price and the point is actually very sharp.
I would not want to depend on this little guy for much, but as a last ditch tool it is a nice little piece. Steel is strong and sharp. I have very large hands and the little loop handle along with the textured "grab" points make this thing  easy for me to hold on to. The internal plastic clip in the sheath holds this knife secure but allows for easy access.
It is nice and small I thought it may be a little bigger based on pictures but it is smaller than I expected. It is  pretty strong I stab a  ply wood a couple times. a hard leather computer chair slashed and stabbed it and then after all that sliced up some paper. It is stil  sharp after all that and didnt even bend or break, I was expecting the tip of it to bend a little after stabbing the plywood like my gi tanto cold steel did but thats for another review.
yes its small ,no one knows i got it, and that why it around my neck.it one of things you just dont go leave the house without.to all woman this is a must have ,you never know when a dope head will go nuts and try to hurt or rob you.
very sharp. awesome knife great qualitiy. only problem after having it for along time the casing got loose and it started to fall out of my boot. which is a big no no. dont need to walk around and have this very very sharp knife fall on the floor and have a kid pick it up.
very sharp almost like a razer i have mine set on my keys like a key chain. fits well in your hand big or small hands dont matter, dont know how useful it would be as a weapon but i think u could do some damage with it. more useful as a tool then a self defense weapon i think i use it to get the battery acid off my car battery lol or just to open things round the house
this little knife is as sharp as they come. i was very please with my order. i carry this knife on my all the time, wearing it around my neck. its sharp enough to shave hair off my arm and the tip is incrediblely sharp. for the price a good buy.
Answer: yes
