What is 'Scary Sharp'?

Scary sharp to me means this. When a blade is so sharp that you know with little effort it could do some serious cutting damage to whatever part of your body it catches. Picture you accidentally nicking your finger, and knowing that it is so sharp it would really eff your finger up. Generally when a knife will tree top hair, that is: you can push your edge into hair standing root to tip, and it just pops when the edge touches, I consider that scary sharp. I am sure definitions vary.
 
Different people have different definitions. Mine is when I discover I'm bleeding and I don't know why.
 
I just try to get my knives as sharp as I can get them with my edgepro. BTW, I currently have two bandaids on, one on each hand.
 
I just recently found out what scary sharp was.

I've sharpened a few knives. It's never bothered me.

I sharpened a Spyderco Endura 4 with a VG-10 blade. I was wiping oil on the blade after and it sliced though the wad of paper towels and into my finger before I knew what happened.

Now I'm a little more careful with that knife.
 
I only own one knife which I have been truly scared of its sharpness. That knife is a Tojiro Shirogami ITK 120mm Petty. For all of you not versed in kitchen knives, its basically a Japanese paring knife with shirogami white #2 carbon steel. It is absurdly light and absurdly thin behind the edge and the white #2 steel is known for taking perhaps the finest edge of any steel used in kitchen knives. This thin gets far beyond hair whittling and cuts phonebook paper with zero resistance and literally almost no sound. The sharpness it can achieve is astounding in and of itself, but the thing that makes this particular knife scary is the weight. Its so light and so well balanced that you really have to pay attention to the edge. For example, taking the ends off of radishes holding the knife in an edge in grip pushing the blade towards your thumb can be a bit daunting knowing that one little slip and that knife will cut deep...fast...
 
I think it is a slight exageration that the knife is so sharp that one should be very cautious handling it because it could cut anything it comes in contact with, including air. Some have also claimed that knives this sharp can actally make the air it cuts bleed. Be very careful...

i'm always tuning my blades too sharp. Sometimes "scary sharp". It's just so difficult staying in key... :)
 
I can take an average freshly sharpened knife and grip the blade pretty firmly or slap the sharpened edge on the pad of my hand. If it's not a toothy edge sometimes I can get a knife to pop hairs but not cut if lightly run across my skin.
When something is sharp enough that even light accidental contact will cut you, then it's scary sharp.
 
I tend not to take my edges thin, about 25 or 30 per side. And when that edge can do the hanging hair test, it's scary sharp. I can't imagine what it would do if I took an edge down to 15 per side. Also, a knife is pretty sharp when it can do circles through a sheet of paper.
 
What is scary sharp?

When a knife is so sharp I am afraid to talk about it. ;=)
 
Felt it. It's bleeding= sharp
Didn't feel it. It's bleeding= pretty sharp
Didn't feel it. It's squirting= scary sharp
 
Scary sharp to me is when a knife can just cut something with no much ease that you don't even realize you cut it.
When it's easy to cut yourself and you don't know it.
When it cuts things you don't want it to.
When it take little to no effort and something just got cut lol.

It's not actually scary, but would be to some people.
 
Touch the blade with anything but your thumbnail and you open up a cut the needs to be closed with super glue.
 
Scary sharp is when you do the 3-finger test and shout "Whoa!" because you didn't expect it to slice right into your fingers.
