TIEGUANJIA Keychain Portable Cutter Multi Tool 6 in 1 Keychain Stainless Steel Key Screwdriver Pocket Tool Key Portable Bottle Opener Key Portable Cutter for Outdoor Camping Adventure Everyday Tools

This is very convenient to keep on a bunch of keys. It can be detached from the bunch just by opening up the blades to get the tools out. The knife doesn't appear to be very sharp as it's been ground at something like a 45 degree angle, however it does have quite a sharp edge on it and will be useful for maybe opening parcels/boxes etc. The serrated part of the blade is quite sharp and aggressively ground. The cross head screwdriver is ok for use in emergencies if nothing else is available, it's not precision ground, but it is cross-shaped and does seem to fit into a good range of screw heads from smaller to larger ones. I wouldn't want to use a lot of force as the metal is quite thin, although it is stainless steel as far as I can tell. The bottle opener is extremely small and due to the design of the tool you are going to cut yourself on one blade or another when opening bottles if you don't use it very carefully. Overall I'm very pleased with it and it will probably prove its self to be very handy when I have to go and work remotely and find myself up a ladder without a proper screwdriver, etc.

I've seen a few of these key tools and this one is okay. All of them are a compromise so you can stick them on a keyring.When you're stuck, it'll open a bottle, undo a screw, etc, but it won't do any of them well. Fine for one or two screws when you don't have a screwdriver - intolerable when you've got twenty screws to undo.But it's nice and small. It's decently made. And it's cheap. So yeah, get it and stick it on your keyring and then you'll be able to get yourself out of a hole when you're stuck without tools.

it does have some utility mainly because its so small, the screwdriver is probably the main letdown but its sturdy and (at time of review £4.59) so its not too expensive.

This TIEGUANJIA Keychain Portable Cutter Multi Tool jus arrives in a small bag, inside the key like device looks well made with nicely smoothed edges and no real sharp points - so if you are putting this on a key ring then it won't tear your pocket lining.As to the tools on it, I've found those a bit lacking. Of the two screwdrivers, the Phillips has a large rounded off end, this is good as it doesn't have a point on to damage anything but when it comes to using it it means it is no good for small screws at all, I've tried several and it won't fit any of the normal things I need a small screwdriver for, taking the cover of a toy battery compartment, taking some screws out of an electronic device, the end is so rounded that it can't work on those kind of screws. I've actually not found a screw it will work on as the two large Philips screws I tried it with it was too small to connect at the edges. It probably fits one or two sizes of screw fine but thats about all. The flat screwdriver is quite narrow but also a little thick so again, no good for small screws and okay but limited on larger ones.The 'micro' eyeglass screwdriver doesn't appear to be there at all, there is a metal lump but there is nothing you could use as a screwdriver.The blade will slice through paper but struggles with card and the bottle opener doesn't work at all and you have to try to hold the blade to use it, this all just seems poorly designed.I thought I might swap this for the mini penknife/bottle opener I have on my key ring currently but realistically this is not a lot of use for 90% of the situations you might hope you could use it for.

Everyone needs one of these. It looks like a slightly chunky key but is actually a multi tool that is very practical to carry around. It's nicely made and very pocket friendly.

This can conveniently be placed on your key ring. Its of decent enough quality and small enough not to take up much space in your pocket. The design is such that you can attach it to a key ring without having to wind it on the ring so its easy to remove for use. The knife is small but just about up to the job of sharpening a pencil. There is a little cross head screwdriver blade and a little tool that can be pressed into service as a flat screwdriver. I can't think of the last time I needed a bottle opener but its there should you need it. This is a fairly inexpensive little item and might make a decent gif, its not exactly a Swiss Army knife though.

The TIEGUANJIA Keychain Portable Cutter Multi Tool is a compact, practical accessory that packs a lot of functionality into a small, keychain-sized design. This 6-in-1 tool includes a key, screwdriver, bottle opener, and cutter, making it highly versatile for outdoor camping, adventures, and everyday tasks. The stainless steel construction feels durable and resistant to wear, while the design is sleek and lightweight, so it doesn’t add bulk to your keychain. The cutter works well for small tasks, and the screwdriver is handy for quick fixes. While it’s not designed for heavy-duty use, it’s perfect for quick, on-the-go tasks. Overall, it’s a great value multi-tool for those who want a portable, all-in-one solution for small, everyday needs.

This is an excellent size for a keychain, and blends perfectly with keys. The stiffness of opening is just right. My only gripe is the sharpness of the cutting edges. The saw teeth are only cast, with no sharpening, and the straight ‘blade’ is only slightly sharper than a conventional paper knife. Useful, just not as useful as it might be.
