My new perfect EDC knife.

This knife came out of the box with its D2 blade quite sharp. It is beautifully designed, well-built enough to last through years of hard use. I like a nice solid, heavy knife, and this doesn't disappoint. The thick, full tang gives the handle a very substantial feel, and G10 scales offer no-slip grip even when dirty and sweaty.

I've gone through a lot of pocket knifes and non have stayed in my pocket for more than a few days.  This is my first EDC that I actually carry every day.  I wasn't looking for a personal defense weapon nor to hunt small game, I just wanted a small pocket knife that was comfortable to carry and easy to use.  Behold the Kershaw 1555TI.. What I absolutely love about this knife is the easy opening.  Flip the nub and POP, it's open - all with one hand.  Can't tell you how convenient that is when you're already struggling with your hands full.  I know a lot of people who opted for the its bigger brother but the smaller size is perfect for a utility knife.  I've also talked with people saying that this is one of the slowest spring assisted knives but besides impressing others, what's the difference between a fraction of second and a smaller fraction of a second?  I don't think that box I'm going to open really cares if it takes a 1/8th of a second longer to flip that blade open.

Only complaint, the edge.  Sharp, yes, at first.  First time I cut a plastic zip-tie it cracked a bit of the edge off.  Also, it doesn't keep the edge as long as some other knives.  From what I've been able to find it uses a decent, not great but "decent", steel from China and one of the issues with this type is edge keeping.  Worst case scenario is that I'll run it through the sharpener a bit more often, no biggie.

I would absolutely recommend this knife to others that are looking for a sturdy and reliable EDC knife.

The perfect EDC knife! Super sharp and the wave feature makes it a very special and handy knife. I like to have the best and this is the best.

I've had hundreds of knives over the years, this one is 100% my favorite. I love this knife. This thing is solid, very well built, fits perfectly in my pocket, it's a big knife but easily an EDC razor sharp out of the box ergonomicly sound. American made and far exceeded my expectations.  If I lose this knife I will be buying the exact same one again. Thanks spyderco for building this knife.

Well made, great feel, easy opening, perfect size, outstanding design and sharp out of the box. Has become my EDC. I bought a second from the mfgr since Amazon was out.

6 months later: Have added few more knives to the "favorites" group (Kershaw, Spyderco, Kubey, Case etc.), but continue to go back to this one as my EDC due to the good feel of the knife in the hand, the weight and build quality. There is no knife I know of at this price and size that can come close in terms of feel and quality (looks is an added bonus). Buying a few more for Christmas for good friends. Kudos to Kubey!

My favorite knife by far. This is my current EDC and sometimes I forget that it is even in my pocket. It is so slim, yet rigid enough to not feel like a cheap piece of crap. Sharpens up nicely and has great edge retention. I normally use a leather strop with green compound to maintain the edge. I recommend this to many people and it is perfect for those who are easing into the EDC world of knives without breaking the bank.

So for me this night was absolutely perfect. I like a big blade in the shape of it is just plain sexy. It's made from Quality Steel and takes a really fine Edge. The handle is very gripping although the edges are slightly Sharp. I took a ceramic stone and radiused all the edges and now I carry this knife everyday. Some people complain that that the blade did not deploy very quickly. Did not find this to be an issue here after opening and closing it many times it seems to work just fine for me and plenty fast enough. I mean how fast is fast mean you flip it it comes out quickly I had no complaints I love this knife

I own a few knives, ranging from pocket knives to larger fixed blades, all for Every Day Carrying / Utility and I must say this is my faovirte knife.

The nice black finish is mate, so its not shiny but is still beautiful in a quieter way. The coating on the knife that is also used on the handle feels incredible, and garuntees to be rust-resistent. It opens incredibly easily, with a good secure lock on it. The clip is reverseable so you can carry it tip up or down. Its blade is perfect, with a nice smooth edge that makes it thin but very strong. I love this knife it goes most everywhere with me.

I received a Spyderco Delica 4 for Christmas. I asked for several knives that were all priced pretty close to this knife. I'm so happy I ended up with this one. You know it's an amazing knife the second you pull it out of it's box. The handle is one of the best handles on a knife I've seen yet. It has phenomenal grip and the handle is just the right size for a nice grip on the knife. The blade comes super sharp and will hold a nice edge with it's VG-10 steel blade. The knife has a very nice pocket clip. The clip is positionable for either tip up or tip down carry and for left handed users or right handed users. I have owned a couple of pocket knives throughout my journey as a boy scout. Most of those knives served me very well, but this knife will never go in my bag that next time I go camping. Instead, it will be clipped to my pocket for when I need it most. This is the very first knife I would consider collectible. I have only heard rumors about how amazing Spyderco's products are. Now that I own one of their knives, I know those rumors are all true. If you're looking for a very good knife that will last you a long time, then this is the knife to go with.

This arrived in my mailbox just a few hours ago.

I unwrapped it and discovered one thing right from the git-go that you might not like... it feels like it was custom made for my hand alone, so DO NOT buy one. Leave them in stock in case I need another one sometime soon!

This is an amazing medium sized folder. The fit and finish are superb. The ergonomics are, for me, quite exceptional. I have large-ish hands (but not huge) and I'm able to get a very secure 3 1/2 finger grip on the handle, which is more than enough for 95% of the everyday tasks this knife will be used for. Opening packages and envelopes, pruning plants & shrubs, cutting string & cord, etc.

There are no hot spots while gripping the handle. The blade deploys smoothlyvwithout hesitation. The frame lock does it's job with no fuss every time. The lock-up is very secure with no play or wiggle, up or down nor side to side.
 The blade itself is very thick for a medium folder and has a straight full bevel to a fine micro bevel that leaves the edge shaving sharp out of the box. The Chris Reeve style frame lock is bank vault tough.

The blue G-10 spacer at the rear of the frame is a nice accent. Spyderco should offer different color choices on these, but blue is nice. The wire pocket clip is reversible and removable and it's pretty beefy so far. There is a lanyard hole high on the rear of the frame which will keep a customer supplied lanyard out of the way of the blade. Jimping on the spine of the blade and top front of the frame is very open and smooth to the touch.

Blade style is close to a modified spear point... somewhere between a spear point and a drop point style. There is just enough belly to allow easy slicing on the draw stroke.

Reading other reviews, I was expecting to be somewhat disappointed but upon close inspection, the Techno looks like the perfect urban EDC folder. A Goldilocks folder; not too big and not too small - just right!

I love this knife.  The size is perfect for a pocket, everyday carry and the one handed opening is perfect.

This knife is a great weekday EDC. It is very light, perfect size for my paws, and as sharp as every other Spyderco I own. It is small enough that I don't notice that it's in my pocket, the handle is strong, and it opens easily and (thankfully) takes some effort to close. Spyderco nailed it with this one.

Wow this knife is awesome. Shaving sharp right out of the box. The balance is perfect, best I've ever felt. I will be making a kydex sheath for it, but there is absolutely nothing wrong with the one that came with it. The fire steel that came with it is crap, couldn't even get one spark with the striker. But I'm rating the knife, not the rod. The coating will be coming off,  I do that with all my knives. Even my Bk-7. The reviews I saw on YouTube had negative comments about the jimpping on the handle, a little work with emmory cloth would solve this problem. Overall a great knife, as soon as I get the new sheath it will be my EDC.
