ASR Tactical Folding Ceramic Razor Blade, Micro EDC Escape Knife Survival Tool

Tiny, but that’s a bad thing. Pretty nifty little non-metallic blade to keep tucked in the coin pocket of your jeans.

I don't know about the escape survival side of things, but these work wonderfully as safe ceramic scoring knifes for cutting capillaries and small glass tubing. Tiny, easy to store anywhere - desk drawer, fist aid kit, purse, car, etc. Extremely sharp, hard ceramic blade. Easily and cleanly cuts kevlar line. Also good as box/tape cutter.

If you want a sharp blade in the smallest possible form factor that isn't exposed i guess this is out. But they aren't as sharp as a razor blade you would shave with. Perhaps that's not possible with ceramic, I'd imagine it would be quit prone to chipping if it was.

This is an interesting and unique item. Basically it is a small (10 mm by 35 mm) ceramic cutter blade that swings out of a plastic shell. The swing out is a very basic hollow brass rivet. It is very small (less than 45 mm long), lightweight and compact. The blade is very sharp, but like most ceramic blades it is very brittle and rather fragile compared to steel. Overall good quality, but the price is a bit steep for such a small, basic tool.

Great little discreet knife

Let's not kid ourselves here. This is not a utility blade or something that you'd use every day. Indeed, while you can use it as a box cutter if you are careful--it is tiny and fragile--you shouldn't. (The blade is barely an inch long.) You know what this thing is for: It's an absolutely last-ditch self-preservation weapon to cut flex cuffs--or something worse. Is it well made for what it is? Absolutely. Is it worth the price? Definitely. (Don't accept a cheap knock-off. The ASR model is the real deal.) But if you are going to get it, you need to consider three things: 1. Where am I going to hide it in my everyday carry; 2. Will I remember to not carry it on an airplane or in a restricted building or space; and 3. Am I prepared to use it if I have to. If you can answer these questions satisfactorily, you should buy this. Otherwise, stay away from it, very far away from it...

Truly teeny. No notch for opening the blade either.

Great very small knife to have on a key chain or in the pocket if you find yourself in need of a cutting device at times. Especially if you work somewhere behind a metal detector. Open, it is about 3 inches. The quality is very good, for the price. This is no Microtech, but can open a box or cut some tape when you need to.
