Cons: None
That other review is super crazy
To be clear, it is initially difficult to retract the blade on most microtechs if you are new to them. After a short period of time they loosen up just a little, your thumb gets stronger, your skin gets tougher on your thumb, and your technique improves so that a week or two later you can’t remember what the problem was initially. All that being said that other review person is a lunatic, they said numerous things that are simply just not correct like how the unnamed steel on thier Kershaw holds an edge longer than M390 and that it’s a knock on an otf that it has an otf mechanism inside. It’s like saying machetes are terrible because they don’t fit in the front pocket of my jeans. Right tool for the right job friend. This knife is just as righteous as every other microtech I’ve handles.

My first OTF
The cons: (note for the most part I consider these cons because I would expect more from a knife priced over $200)• I hoped to use this knife semi-regularly, not just stow it away. For me it's not so useful, and surely I should've anticipated that, but some things you have to learn by trial. The problem is that any residue whatsoever remaining on the blade before closing accumulates inside the knife handle, on the spring and sliding mechanisms, affecting the action. I used mine to open a few taped boxes, for example, and ever since the mechanism hasn't been the same. It won't deploy fully and I have to snap it out the rest of the way with a flick of the wrist, until I get out the goo-gone and clean the blade off again. The goo-gone only helps for a while, essentially because it's functioning briefly as a lubricant to the spring action. If you plan to actually use this knife for anything, you will want to wipe the blade well before closing after every single use. So mine just sits in the drawer now.• The black coating has scratched off at the handle corners from very minimal use and pocket carrying. The black on the blade is similarly not super stable for a $225 knife. It quickly began showing wear, polishing, and small scratches from very minimal use.• It's a little harder to sharpen the edge than most of my knives, and I have a harder time keeping it very sharp than other knives in my collection.• The button is hard to activate and takes some getting used to if you've never had an OTF auto. I don't find it practical. For me, it's easier to open a flip knife than this thing, which defeats the purpose of the fancy mechanism.• You can't open the handle up to self-service due to proprietary screw heads.Pros:• It's cool. It's beautiful. The blade steel, M390 is excellent and holds an edge well (though for everyday use I prefer the steel of my much cheaper Kershaw Leek – its easier to sharpen and stays sharp longer as well).• Great, strong, tip-down clip.• Arrived very sharp.• The glass breaker on the butt end of the handle is brilliant and could come in handy.• Feels great in the hand. Smart handle design.• Blood groove (though, why does it only run the lower half of the blade?)
