Is this knife assisted opening at all?I'm torn between this and the Kershaw Cryo 2.

I own both the Rat 1 and the Cryo 2 in plain and blackwash finish, and I can tell you that while the Rat 1 is not assisted open, I would ask you to consider that it opens lightning fast, just as fast as an assisted open, using only the thumb stud.I own many many knives, and I kind of got spoiled on the assisted open, but let me tell you, this thing opens mind blowingly fast, with just a flick of the thumb, so don't get to hung up on the assisted open feature.One other aside, I have had a spring break on my Cryo 2, and it was worthless to open with only the flipper and no spring. Also, the Cryo 2 will squeak and rattle around if the grease ever washes out. The spring is loose, especially closed, so you can actually rattle it around if there is no grease in there. I actually had to order white grease after I made the mistake of "cleaning" the knife, and inadvertently washed out all the grease. So keep that in mind also, there is no spring on the Rat 1, also no grease and no chance of any "mechanism" breaking.

dose the knife have a pocket clip

Yes, the knife does have a pocket clip; a good sturdy one in my opinion.

Is this made of stainless steel? can it be used as legal pocket carry and as self defense knife?

The blade steel is AUS-8, Japanese stainless steel. Whether or not it's legal to carry depends on your locality. This knife would not be the best for self defense, but it would also not be the worst.

does this model have satin, not black plain blade?

Simon - The blade is lightly brushed AUS 8 steel. The Rat I purchased is the Model 1. If you go to YouTube, click on Prepared Mind 101's link. He gives a very good review of this particular knife. I think that it is a great value for the price. It is well constructed, has an adjustable spring clip and comes out of the box razor sharp. For the price, I bought 3.
