Non-Metallic Ceramic Razor Blade (Wear-Resistant Non-Dulling)

These things are amazing. Smaller than I expected, even though dimensions were given, but that makes them very easy to hide on your person, I ordered two, and am going to order several more. These are sharp, sliced through paper like butter, and is as effective as my SOG knife. Very happy with this product, and with ASRT. Would have given 7 stars if available.

I was disappointed with how small this blade is until I was watching NatGeo one day and found out that in manufacturing, sharpness counts.I also found out that Zirconia can hold an edge much much, MUCH better than ANY metal. Not only that, but Zirconia can provide an edge that is Very Much sharper than any other material. Diamonds are the thing that can be used to sharpen these babies!Zirconia cannot be detected with a metal detector, ( I do NOT condone using this or any other blade for breaking the Law!) but, if you're being held against your will by some madman, or being herded into a FEMA camp, this item could help you out in any of a thousand ways.The little, tiny, soft plastic tube this blade is stored in confused me at first.... But I'm a bit anal :-)

This razor is extremely sharp and comes delivered in a small plastic tube. If you haven't figured it out from the other reviews, yes, the blade is small. But, that's the point - it's the "Covert Hide-Out Ceramic Razor Blade". Emphasis on covert. It's not intended to be an everyday use item. DO NOT BUY THIS IF YOU ARE LOOKING FOR A LARGER BLADE TO USE FREQUENTLY - YOU WILL NOT BE PLEASED.

I have spent the past couple of months trying to decide on what would be a decent tactical blade for me, I needed a small blade and that could help me out in a pinch. I really considered SOG's micron 2 and several other blades however this blade turned out to be perfect, despite some of the things I was a little unaware of. Some of the things I was unaware, before I bought the blade is actually how small 30mm x 10mm really is. Even though this blade looks rather small it cut through every box I had and through various other material with ease. I am actually confident that if I need to open a box, letter or even cut a pair of plastic handcuffs, I will be prepared. One thing that came to mind was to see if airport security would detect these types of blades, however upon further thought of walking into a plane with any type of blade I decided that would not be such a great idea. (although to be fair I don't think the metal detects would sense it, I know their x ray scanners can detect it, seeing as how this blade must be made of a very dense material to be "non-dulling").Overall, if you are looking for a really small, compact, thin, durable, covert last ditch, get me out a pinch blade, then you should definitely consider this type of blade.p.s. when opening the package you should try to be gentle to get the blade out of the cylinder compartment because if can get 'stuck'.

Cuts through boxes super fast!

I’m not sure if this is supposed have a handle but it’s too small (an inch if that) to handle safely without mechanical aid.

It was perfect and durable

Like the picture they show, these are small. Altho, until you get them, it's hard to believe. I was expecting a razor blade size, not an itsy-bitsy thing! You can barely hold them - like holding an Exacto knife blade, but they're too wide to fit into an Exacto knife handle.. locking forecepts worked tho ..They may be useful for some special circumstances, they're not garbage.Oh well, at least they saved in material costs. I'll certainly not buy any more, nor recommend these to anyone.
