Apart from the fact that this is a 6-inch "axe", the design is one not to be trusted. the handle is small, has sharp edges, and when the spring wears in, it slips, and you wind up pinching your fingers. The hammer is less useful than a solid hammer, due to the fact that you have to squeeze the vice grip to hold it firmly (this goes for if you're daft enough to be trying to use this as an axe, too) This also makes the latch at the bottom detach, which makes the handle spring out (if the spring is still working). Ever use a pocketknife saw to saw anything? If you have, you know it's useless. Same with the pocketknife, which suffers a dexterity handicap of -10 due to the fact that it's attached to the rear-end of a hammer and "axe". The wire-cutter may work okay, if there's a lot of space around the wire to fit the head of this axe and hammer mutant, and if the wire is very thin, because you're hands will be in agony the first time you have to put any real pressure on that tiny handle. the spanners, drivers and other turning tools, you have to spin the entire bulk of this thing around EACH TIME you turn the screw/nut/bolt ONCE. That's IF you have enough clearance to do that (10-inch diameter at least). You've got no leverage with a tool like this, and will wind up putting way more force into it than is necessary with this great new invention called a "lever", which comes on all socket-wrench sets as standard. Do yourself a favour and rub salted lemonjuice sandpaper into both eyes before attempting this. That will reduce the pain you feel when the tool slips and you jam your hand+fingers+"axe" into the nearest hard surface. Trying to fix a bike? Those spokes will take the flesh right off your knuckles.
If you're out to teach your kids wilderness handicraft, or how to fix something, show them you have some sense and teach them the value of having proper tools for the job. If you want to fix things on the fly, carry a small toolbox in your car (for $40 you can have even buy the box!). If you want a 6-inch hammer and axe bulging out of your (torn) jeans pocket... well, then this is the "tool" for you!
