I got two for xmas, one for me and for a buddy. What a wicked knife, fast to open, extremely sharp and well made. I have over 50 different CKRT Knives.All of them a great knife. At first, the Hissatsu, for the first few times you would might say " a little hard to open" but after that no problem. The Hissatsu opens differently then all others CRKT, that may be why must of these posts are talking about. Mr Williams designed and built a great tatical knife which is unconventical to the "standard tatical knife". If you understand knife making and the history of knife blades, specialy for tatical use. The Hissatsu is not a KBAR, which is a fine knife, but look at the Hissatsu has more history in design and use. A far superior design use for todays urban tatical use. Hissatsu great knife

I BOUGHT A HISSATSU FOLDER ABOUT 4 YEARS AGO. IT'S GREAT AND STURDY FOLDING KNIFE, AND MAKES MOST OF MY FRIEND'S KNIFES LOOK LIKE JUNK. IT'S ALL BUSINESS

This is not a "Tatical" knife allthe opening stress is on a specific point on the thumb. I recently had a burn on the finger tips and working with ths knife was very painful - give it to Kit Carson, he will perfect it. Thumbs down not worth the pain.

crkt yall hav good tactical kives but the liner auto locks r just weak when i accdintly droped my crkt m16 n when iwas about 2 pick it i saw a peace of metal that s sizes of a dime it was the liner auto lock it broke after the drop an i was like al hell i was disappointed in the lock that didit stand up to its name the worlds safest kinfe if it brakes in a bad situation well s o l there gose a life that may prevent lost life b cuz of mechanica flaws that feils to its standards life is very heavy very precious mechanica flaws will take life if their r no improvement a life will b lost by whatever bad situation this is whatit shulod b CRKT takes personal responsibility seriously. Only you are responsible for your families safety and your own safety. To do this you n ***CRKT RESPONSE CRKT Takes personal safety very seriously. It is the primary reason why we designed the AutoLAWKS system. When both of the locks are engaged (the liner and the AutoLAWKS) the knife becomes a virtual fixed blade. Many of our service oriented and military customers have appreciated this evolution of lock design. If your one of the locks on your knife is defective at all, please reach out to us via Customer Service. We have one of the best CS team and warranty in the industry. CRKT

I have bought two Hissatsu Folders and I have been very pleased with them. I found the 'Outburst Assist' allows me to be ready for anything almost instantly. and after some practice (and the knife loosening up a bit) I can open and close the knife one handed quickly and efficiently. This is an excellent knife for the money and I would recommended it to anyone who needs a reliable tactical folding knife. Robert Glenview, Illinois

Just received this knife today, Wicked Fast And Wicked Sharp , Cut Myself with it. Awesome Edge, by far the Sharpest Blade I've Ever owned Straight out of the Box. Took the belt clip off for either pockcet carry.James Williams and CRKT are right on point with this Knife. David N.C.

Very difficult to open... I sent the first one back asking that it be repaired or replaced. Received the 2nd one and it was likewise very difficult, if not impossible to open with one hand. After hundreds of two hand opening and several different oils, it is now at the point where I can sometimes open it if it is freshly oiled. Beautiful knife, poor operating technology Several reviews said they "are sure it will loosen up" of which I would like to hear follow up from them. ***CRKT Response - This knife is specifically designed for operators in tactical and military situations. The Hissatsu only opens with a decisive action. Over time it does tend to open a little easier, however always with a strong and prominent click. The last sound you do not want to hear in a dark jungle or cave. If you feel your Hissatsu is defective, please send back and we will definitely take care of it. CRKT

Like the other reviewers said, it is very stiff to get opened. I applied some gun oil to the pivot and it did loosen it up a bit, but it is still hard to open. Once you get it started then it springs right open the rest of the way. I needed to put a hole in my gun belt and it went through the leather like it was butter. I love this knife. Keep up the good work.

I got several CRKT knives and all are well built and great knives. This one however is one I don't care for much, sometimes it opens very easy and sometimes it hurts my thumb to get it to come open, I like the handles but seem to big for the blade. With this style blade I think it needs to be at least 6" long which may be a little much for some. It does seem to have the great CRKT quallity, just not for me. I would like to see this knife with a 6" blade. Just my thoughts. David J.
