Cardsharp 2 by Iain Sinclair

This is an awesome product for someone who traditionally does not like knives. It fits perfectly into my wallet and is barely noticeable until someone needs to cut through something and I'm ready! I'm trying to be careful not to use it too much as the plastic that bends might become breakable at some point, but I'm assuming it's designed with this in mind - overall an awesome and unique product.

I wouldnt dissuade you from purchasing this thing, in-fact i still am happy about dropping a few bucks on it...The product is exactly what youd expect, and even seems somewhat durable or long lasting, although i cant confirm this since ive only had it a few weeks.I would have definitely givin this 5 stars if it werent for one serious problem with the knife...My blade has EIGHT(8) noticeable nicks on its cutting edge.... they look all equal in distance, as if knocked across other blades in a rack or by a machine. The edge is quite sharp, and very thin.. so im not sure if the average person could polish/grind them out, doubt i can.THIS IS A HUGE BUMMER.. and im not sure if i just got a faulty draw, or if this is commonplace with the product - either way BE WARNED.

I've had a few of these fold-up knives in the past few years, none as nice as this one. Some are cheap imitations that only fold/unfold a couple of times before failing or refusing to unfold securely. There is no comfort in a knife like this that comes unsnapped and becomes a hazard in your hand. Some are made of cheap steel that won't hold an edge. This one, despite the low price, seems to be up to the standard of the original (which I've only seen and never owned). Sharp, very crisp in deployment, it snaps together into a nice rigid handle for the knife. It can't be an original Iain Sinclair but it looks and feels and works the same as far as I can tell. I'll update the review if anything changes or it fails prematurely.

First of all, I was skeptical. This knife didn't come in the mail very sharp. I ran it through my diamond kitchen knife sharpener for a few passes and it became razor sharp. This product exceeded my expectation by a long shot. For a few bucks you can have a very sharp knife in your wallet and won't even notice it. Of course it's not something you can expect to use daily but as a backup or something to have just in case, I can't imagine any better product. It's about the thickness of two credit cards in your wallet and, when assembled, is much more sturdy than expected. I keep this in my wallet all of the time and usually also carry a small Kershaw Chive as my primary pocket knife for every day use.Don't buy this as an every day carry knife you expect to use consistently but do buy it if you find your self needing a sharp knife every once in a while. Very well built given it's applications. Shipping was pretty slow (about 3 weeks) but worth the wait. If you want to spend the extra couple bucks, buy from an American seller to get it faster than I did instead of a Chinese seller.

I bought this knife for two reasons. First I'm a gadget/ design freak- I like seeing everyday items that are thought out and well executed. Second, I wanted the ultimate 'backup' blade, small, sharp and always available ( to turn over to TSA, for instance.) This blade satisfied those criteria. I carried it for almost a year, used it a few time, shared the 'cool' factor with several friends and really had no issues. That is, until the half-round blade lock failed. I keep my wallet in a front pants pocket for security. Imagine my dismay when I went into said pocket, only to quickly withdraw my hand with a beautifully clean 3/4" incision across my thumb. I have contacted the company to no avail and the Amazon vendor I purchased from has a minimal presence and no way to communicate. Looks like I'll be hacking some sort of retainer if I want to continue to carry this thing. The takeaway? Yeah, it's cool, but customer support is sadly lacking...

It is easily concealed and it is helpful if I leave my pocket knife at home. It is not very sharp though.

I bought ten cardsharps--one for myself and the rest for gifts. Everyone who has received one has just loved it. Great design--elegant and useful!

Are you ready for a knife in your...wallet? This nifty little knife can always be with you in a credit card slot. There are knockoffs, so beware, but this item definitely exceeds expectations by having a keen edge, and an easy delivery system. Expecting a quick deploy? No, this is not happening, it takes about 30 seconds to bring the knife to a sealed mode, 10-15 if you get quick. The edge is easy to keep but more importantly the price is right.
