The knife itself is flawless. Some people have reviews about knocks offs. That is no ones fault but their own for buying from private sellers.

The sheath is okay too. However, the clip is a bit odd. Some may like it, some may not. I personally don't have a problem with it, other than it is not the most secure thing. I wear a reinforced gun belt made by Alien Gear, and it clips on just fine, but it is far from completely secure. It could be ripped off with the proper force, but honestly, you would just rip the knife out first anyways. I may invest in a custom kydex sheath, but for now, it works great. You can swap the metal clip from side to side if you need to. There is one review complaining about bending the metal. I tried with a gerber and it takes a ton of force to do so. If you bend this metal, it's your own fault.

I highly recommend you get this product if you are so much as contemplating the idea of carrying a fixed knife for personal defense. Also, take some training. Please, take some training. At the very least, spend time unsheathing and re-sheathing it, as well as a practicing a proper grip.

I honestly cannot think of anything negative to say here. I do not plan on cutting anything with this blade. That is why I carry a normal fold away blade for. Don't get carried away. Use this for what it is intended for instead of trying to cut down a tree.

Ships nice and secure.

Pictures for reference.

I bought it to wear horizontally on my left side belt for a left hand draw. The knife is great, the sheath is great quality and fits the knife well, but the belt clip is designed for vertical carry only. I managed to reorient the belt clip using the included hardware to an angle more conducive to horizontal carry but the clip is long enough that I found it uncomfortable to wear in that configuration as the corners dig into my belly when seated.
I purchased a third party sheath intended for horizontal carry that works better for that position. It doesn't have quite as good a knife fit upon insertion and the retention is not quite as positive, although it is adequate.
If Ka-Bar would design their sheath and clip or an optional one for horizontal wear, sized so that it doesn't dig into anything above the belt when the wearer is seated, it would be perfect.
I use it as a self defense tool when carrying my handgun concealed. It is most likely to be needed in a CQB circumstance when I'm trying to protect my weapon with my right hand and need to draw and deploy the knife with my left to create separation between me and my attacker. Pocket folders are generally useless in this situation as detailed by many police documented reports regardless of the training and familiarity with the knife by its user, hence the need for a fixed blade knife and one one that can be drawn quickly using gross motor skills under physical duress by ones off hand, not strong hand.
That is why most who buy this length "cop knife" buy it and how they intend to use it, as a concealed stand off tool. Uniformed police actually buy and use its larger brother with a longer blade as they don't have to conceal it and vertical orientation on their duty belt or vest is the preferred carry method.
Great knife, fair price, good quality sheath and clip, just not the positioning of the sheath for horizontal belt wear, at least for folks like me. Maybe if I was taller or thinner, it would be okay but I'm built about like the average American male these days and live in a south western climate where anything on my belt is going to be next to bare skin.

I've been carrying the TDI knife for a while now especially as a back up to a concealed firearm or on it's own in areas where firearms where not legally allowed. I've been very pleased with it and it handles very well in either hand and in pretty much any full grip up or down. I had a chance to do force on force with training knives and the grip being small and hard to manipulate out of your hand is a definite plus, as is a small and dirt simple blade. Draw from retention or contact, punch/stab everything you can get at. Thankfully I've never drawn it or anything else but confident that this piece of gear will do the job.

One major issue holding back this knife. I've used both the old and the newer sheath it ships with. The belt clip version is better but still bulky and uncomfortable. The PHLster sheath is the one this knife deserves handsdown. It's lighter, thinner, easier to put on and off. The ability to adjust the angle makes the knife more concealable and the lower profile+belt loops allows you to mount in inside the belt or even between a velcro inner and outer duty belt. The Amazon link is below but it's available direct from PHLster as well as SnakeHound Machine. If you are serious about carrying this knife as a defensive tool the PHLster sheath should be a no brainer.
PHLster TDI Fightworthy Sheath

This knife is just great. Perfect for EDC. First, the blade is a perfect size for every day use like cutting boxes, packages, etc. And also a great size for self defense if that time ever came. The handle and ergonomics of the design is great. The feel is perfect, grip is great and blade is pretty thick solid and super sharp.
The sheath is also great a well designed. The retention is tight and the reversible clip work perfect.

I have this version and the longer tanto version with the locking sheath. Both are top notch great!

A must have! It's a Ka-Bar!

Got this from BladeShop.

I really love kabar and they're great comfortable knives and are ascetically pleasing and have a nice useful design to them. I've been wearing it for a while now and it's really comfortable even in the sitting position when worn between 12 and 1 next to the belt buckle, unless you're carrying a firearm then you want it on your non-dominant side as a back up. This is my second TDI. The first one I bought came with a belt attachment that you had to slide your belt through. It was VERY annoying and uncomfortable and I hated it. The knife was great, but the sheath was not well design. They fixed the problem with this belt clip. I will try to comment and update later on its longevity, but it's very easy to attach to a belt and take off, but it will NEVER pull off when you pull the knife out. It's well designed and a far better design then they originally had about 10 years ago.

On a side note, amazon recommended that I buy this along with a belt clip... being used to this model 10 years ago and only getting a sheath, I assumed the belt clip was sold separately, so I picked it up. Turns out the knife comes with the sheath and belt clip attached... oh well, I guess I have a back up one. I'm not sure what people are talking about though when they say no tools are provided because the extra belt clip I received came with tools, and the actual knife in the box came with the same tool... so I don't know where they got theirs from, but it's supposed to come with them.
