Question: what steel is this?
Document: This knife looks goood! Everything is the same in this model as it is in the standard one other than the color and the blade steel. The knife came extremely sharp and has so far held its edge well primarily cutting cardboard boxes and heavy duty shipping tape. Zero bladeplay in any direction and the blade rockets out with a solid snap. Made a quick video of it and included the link here for anyone that wants a close up look:Kershaw blur green smoke: http://youtu.be/elG3LWdSmLs
i have a comparison review with  a black sandvik version with lots of pictures  and comparisons of steels during tests on edc forums and 24 hour campfire forum. i agree with the pros of the other reviewrs here
Very nice kershaw. Got it after a week or so in mail. Was very sharp and ready for use
This knife is everything it should be, its sharp, I love the serrated edge and it can be used for many tasks. The only negative part is that Im left handed and it is a little more difficult to open with that hand for some reason. I believe that with a little practice it wont be a problem.
This knife is awesome, It opens quick, looks awesome and fits nicely into my boot. I will be purchasing another.
This is a good looking knife. I own quite a few blurs and this is one of the better looking ones. The blur is known for its thumb stud opening and this one is no different. It pops open and locks in place with one push of the thumb. Very sharp and I love the tanto blade. The blurs are excellent knives and they come in different styles and colors. I loved the smoked green look of this and it looks just as good in person as it does on the picture.
Them knife is well made. the blade comes out fast it locks tight and it is sharp. I find the knife practical and it meets my needs in multiple situations.
Opens smoothly and locks up very well with zero play in any direction. Easy to close one-handed. Very grippy handle. Sharp enough to shave with. Just a great piece.
Open and closes smooth, and like someone else said, it feels great in your hand. Lightweight and slim for such a good sized blade. Mine ended up coming with plenty of green, so I am a happy customer. Great price and fast shipping from Amazon with Wisemen Trading and Supply. Get one before they are gone!
Love my Keshawn blade...the color is cool from one side but I wish the back side was painted the same. This is my six tanto blade , it's how much I like kershaw brand.
Answer: yes
