To use the pliers/wrench/crimper you just need to flip the other items back which allows them to act as handles and have a way to use the wrench part. It is not heavy duty though can get many jobs done in a pinch and quite amazing the number of things this can do in such a small package. I am impressed that it contains all the items it does for the price. It is not heavy duty but neither is it poor quality where this unit is likely to get damage during normal use. It also comes with a lifetime warranty and is priced under 9 bucks so I have been very satisfied with it but so far only need to use the screw drivers. One can get sturdier more expensive mutlitools but I have not seen one that can do more for being so timy and fit on a keychain.

It says it comes it the following Two hex wrenches (1/4″ and 7/16″ both incorporated in to the same head of the wrench which can be used as light duty pliers as well. This also doubles as the pliers and under the jaws of the pliers are the wire crimpers. The six screw dirvers, 3 of each are all in useful sizes. The rulers are just marks engraved on the side of the tool and so short I am not sure what they can be used for in a practical sense but better to have them there than not. It also says in incorporates a hand drill. This is a very thin drill that would make a very small hole. I am not sure how useful this would be or how sturdy but again it is better to have it than not. I expect one needs to be careful with that being so thin so it does not break. Swiss tech micro max 19 in 1, However I am sure it is capable of making a tiny hole in to various materials, though I would say softer than most metals. The file is not that great in my opinion, but it has one.

In my opinion the most useful thing about this tool is that for it’s small size you get a good variety of usable small screwdrivers and a working wrench and pliers. Those are the only items I see myself actually using but you never know. But those alone are pretty impressive for a tool that folds in to less than two inches square.

So to even have somewhat useful pliers and wrenches fold out of such a small item is very unusual. Of course a large strong steel multi tool such as an SOG or Leatherman type is going to be able to handle tougher duties and have more leverage to do them. But this is not a competitor for those. This is an inexpensive keychain items for well under 10 bucks. Viewed in that light it is quite impressive and I am sure will come in handy when I am not around my usual set or tools. If this is on your keychain it will be there whenever you need it to do all the tasks it is capable of. I am very impressed with what this does for it’s size and price. I have recently been purchasing small items specifically to be compact and fit on a keychain to cover as many duties are I run in to and this has been an excellent addition to the set. I am very happy with it for the size and price.
