U4 Pro+ Plus Titanium Carabiner Keychain Knife, EDC Multitool Pocket Clip with Replaceable Sharp Blade, Dual-bit Screwdriver and Ruler, Emergencies/Office

These are awesome little items. We purchased a good number of these as gifts. A novel idea that is very useful.

Awesome product - I like the unique multi-tool features that are tucked into this. Quality is excellent. I use it on my keychain as my main EDC.

Update: I did receive the item finally and I was fairly impressed with it. Just know the scalpel part doesn't lock it's just the screwdriver part. Almost found that out the hard way. It took atleast a good week to arrive. When it finally did I was excited to check it out. I opened the Amazon package and dumped out a plastic container wondering if it would actually be good or not. As soon as I open the box I was greeted with nothing but empty air.. I had to call Amazon to complain about it because there is no option for 'package is ok, product missing from it's retail container'. To top it all off, Amazon requests that I send the empty freaking box back to prove it was empty.. Causing me a huge inconvenience to try to make it to a UPS Store and waste the planets resources to send a box of air back that proves nothing.. I included a picture of the air incase anyone is curious what it looks like. I know many things could have happened but I figure most likely it was a QC issue and they just missed that it was an empty box with air included. If so, it should have been easy enough to check the weight before shipping and really is inexcusable.. So, I'm gunna leave one star, which seems fair, until I actually get something besides a box of atmosphere. I'll report back how it is when I do. As far as features go, I'd say the air isn't very sturdy at all, and neither is the box the air came in. Horrible value too for an almost $50 box of air of unknown origin. Both of those are easily one star. Though, I will say though that the air is extremely lightweight, which makes it a breeze to carry in any EDC loadout, and therefore gets a lofty 5 stars here.

Is exactly as advertised.

This thing is NOT cheap, but it's very well made and very useful to me. I especially appreciate that the blade is an easily replaceable and common standard #11 blade, which can also be quickly and easily removed and discarded before going through a TSA line.

This clip is extremely lightweight, with an ample arc/loop for it's size making it easy to open and attached to things. The blade blends into the body of the clip becoming very inconspicuous. The blade is tiny, but very sturdy and sharp enough to take care of most day to day needs in a home or office environment. I wouldn't make it my daily carry for heavy regular use, but good for shorts in the summer or attaching to backtrack or keyring for light irregular use.

I love this keychain. The blade is very shape and the device includes replacement blades. I like how the tools lock in place to prevent the screwdriver head from separating in your pocket. Light weight but strong construction.

The aspects of the U4 Pro that are the same as the U4 are just as great: lightweight titanium, double carabiner, and the scalpel blade. The "pro" feature I don't think is worth it. It adds 50% more weight (16 g for the U4, 24 g for the U4 Pro) because of the extra steel needed. I will say, though, it's not any bulkier. It feels very similar in your pocket. My main gripe was the screwdriver bit could not come out with my fingers. I'd have to get a pair of pliers to pull it out. It is so small and slippery, you can't get a good handle. And since it's held in place by a strong magnet...and the machining was just a little off, so there's a little extra friction when the bit slides in and out...that I can't get the bit out. Obviously I'm not going to carry around a pair of pliers so I can change the bit on this thing! Maybe it was just mine, and the rest are fine...or maybe it would wear in...not sure. But I can't recommend it based on my experience. (Further, since the Phillips bit is a size 0, I really can't imagine a scenario when I'd use it. Maybe tightening a screw on a pair of glasses? That is such a small size, it's not a realistic do-it-all screwdriver bit. The flathead is a little more usable, but probably also not something the average person would ever actually use do to its small size. Long story short, stick with the U4 non-Pro.

Well designed. Very handy. Don't put it on yourself or in your hand luggage when flying

No es malo pero no sé si vale lo que cuesta.

Funciona muy bien, pero creo que esta un poco caro
