ScrewpopToolkey 15-in-1 Multi-Tool Ultra Thin Lightweight for Keychain and Carabiner Stainless Steel Silver

Made it through security there and back. Don't know if I ever actually used it.

When the tool is on my snap with the other keys, the magnet attached to one of them, making it annoying to carry.This is the only downside I found.Wish there was a way to remove the magnet.

This multi-tool is an awesome and incredibly useful addition to my key chain!Performs all of its promised functions well and also comes with a separate small pen that can go on the key chain as well!If you're looking for a good, lightweight, portable multi-tool that can fit on your key chain, this is it!

Okay, so you can't exactly build a house with this key shaped tool, but it's good for travel when you need to tighten a screw or cut a tag. You'll need to get an additional travel set of screw drivers, as the flat & Phillips head is small. But for less than $15.00, it's a well built, easy to tuck away travel tool.

Great design and construction. Fits along side other keys on keyring in pocket.

This replaces a key tool I carried for a long time. This one is much better. It's VERY lightweight. Almost can't feel it light.The serrated knife is sharp but not dangerous like a standard blade. The sharp areas are within the notches, so it's not like having a razor blade on the key-chain.The first thing I used it for was tightening a loose pan handle. I was in the kitchen when I was putting it on the keys, and remembered the loose handle. It fit the #2 Phillips well, and didn't mark the tool at all.I like the bit hole. It fits standard 1/4 inch driver bits.The magnet is also handy. I needed to pick up a sewing needle that fell on the floor, and there is it on the keys at all times. Also for checking ferrous metal when you need to. The only thing is I had to arrange the keys to keep the steel things away from it so it wouldn't bunch up the items on the ring. It's a strong magnet.I like that the ruler is inset or molded into the tool. My last one was silkscreen, and that lasted all of a few hours. These ruler markings aren't going away anytime soon.There's a fine file on the back edge.The "tag buster" strips CAT 5 wire nicely.The wrench is stepped, so metric on side, SAE the other.All in all, a very worthy EDC item to have.

I am one of those "everyday carry" types (carry everything with you that you use every day), although I go a step further and like to carry the absolute minimum amount of things for the maximum amount of situations I find myself in, so I love little multi-purpose tools like this.I was particularly drawn to the box-scoring tip. I try not to carry blades with me, ever since I accidentally went into a courthouse with a large folding knife, but I find myself always needing to pierce tape to open boxes. I used my keys for a while but got tired of tape residue so I switched to carrying a small prybar for the job, but the pointy ends of those sliced a pocket open once so ... tl;dr, I love the little tip on the end of this for piercing and slicing tape. And because it is not a blade, it's TSA-compliant! (yes there's a serrated edge but its not too sharp)I also really love the tag buster/wire stripper in the tip. Ever find yourself needing to run some emergency ethernet cable from a bulk spool and your cap cincher doesn't have a wire stripper? No? Well, this'll come in handy if that ever happens lol.It's very light yet very sturdy feeling, and since it resembles a key (albeit a large one), you could slip this on your house key ring for easy access. Or, since it has a tiny neodymium magnet built-in, pop it on the fridge!

Never hurts to have a multi-tool on hand. I don't think the metal is very strong, and the magnet sticks to the keyring. Be careful when reaching into a pocket for it, the saw teeth are sharp.
