SOG Flint 4.3" Survival & Defense Portable Compact Tool for Outdoors and Emergencies | Includes Glass Breaker and Whistle

Haven’t had to use the glass breaker part in a real life situation, just on empty bottles. It works, the whistle is nice and used to wrangle my nieces and nephews or play with them. It’s nice and sturdy, has a great feel. It is small and can be lost. Overall a nice addition to your EDC

First, it is indeed tiny BUT thats exactly what makes it great to have as EDC item. As it is a small volume whistle, one must blow forcefully to get good volume. This, a AAA flashlight, and a small neck knife make a great "Trinity" to have on at all times. Any larger and heavier just reduces chances on one having it available-I'd rather have a small glass breaker immediately when riding with others than a huge full sized one sitting unavailable to me in my vehicle.

I am going to keep this and put it in a go-bag, but I am not convinced it is entirely useful.The whistle is very high pitched and will not carry all that far and definitely not as loud as other emergency whistles I have blown. Also, it is a metal whistle so unsuited for very cold weather, unless you want it stuck to your lips.The ferro rod is pretty small, and so is the stash of tinder, but I think I could definitely start a fire with this. The tinder, a small piece of steel wool, is good for one use. The rod will last for a bunch of fires, but it is pretty thin. Interestingly, it is threaded. I don't know if I could find a replacement, but it is replaceable, which is always nice.In any case, I'll toss this into a kit that I hope to never need, and I may not see it again.

A little smaller than I expected. The glass breaking features seams limited. The item is very light weight. Not sure it would be effective. But, it is compact and is easy to carry and pack. Being new it is very tight and difficult, at first, to separate. Cautiously recommended.

I have not had the problems others have written about. Doesn't come apart in my pocket, and the ring is solid and has not come apart. Two of the three screw in compartments are sealed with an o-ring. The fire starter produces significant spark and it comes with the steel wool tinder, but I will replace that as steel wool attracts moisture and rust. I will put a small ball of cotton soaked in 100 percent petroleum jelly as that is an awesome tinder and it does not attract moisture. The whistle is not really very effective, but will alert dogs. I have another whistle I carry constantly, so that wasn't a deal breaker for me. I have not tried the glass breaker, but feel it will work well. I will try it out next time I see a junked car. It would work as a self defense tool if you know how to wield it, which most people don't. Fits compact into the hand and is easily concealable.

I carry this daily in my front jeans pocket. I attached a Tec P-7 clip to it and it hangs in my pocket along the outside of my leg. I hardly notice it is there. The whistle is loud enough to be heard ~1/4-1/2 down the road. I've not tried to break any glass with the tip. The ferro rod throws sparks, I don't expect a full cascade of them but it throws a spark that in a do or die situation will be more than nothing. A good /additional/ tool in the EDC kit. I wouldn't want to solely rely on this for anything beyond the emergency whistle. The fire needs are always best served by a bic lighter. The glass breaker would be better if it were a bit bigger with something to keep your hand from slipping forward etc.

Don’t use as key chain. Loop for connecting to a keychain came off twice and lost tool on third time. So I couldn’t tell you if it was actually worth a crap or not. Poorly designed

This is smaller than I expected; it's 4 in. It weights almost nothing. It has a great high DB shrill whistle. And I just discovered, a little bit of steel wool tinder. I also searched the TSA website and can't find anything that would exclude this from carry on (I update if that turns out not to be true).
