Hair poppin sharp

[yog]

Someone over at blade forums just gave their variation of "hair poppin sharp" verses "shaving sharp". According to their standard hair poppin sharp was when a knife was sharp enough to take hair arm off an arm withought touching the arm.



Well, I couldn't resist could I ?. Calypso Jnr Lwt held about 3-4 mm above the arm and moved slowly through the arm hair. Well blow me down, but it was cutting hair like nobodies business.

I knew it was shaving sharp, I just didn't realise it was hair poppin sharp.

That's the test I feel indicates my knives are sharp as I'll ever need them to be - and fairly easy to get with Spyderco Knives.

I don't know if I've ever gotten a knife to "scary sharp" since the test involves cutting myself!!

I would still like to know how Sal would describe (and test) what he once called "crispy sharp"

That's a sharp blade, all right! <img src="smile.gif" width=15 height=15 align=middle border=0> I like to keep my stuff shaving, but I stop on the corners of the whites. It's sharp enough to shave, but still has some teeth to grab with.

Now, shaving with a Case SS blade is nearly impossible, but the 204's a great help there, too.

Keepin' it real...real sharp, that is.

I've never been able to get a knife hair-popping sharp, but what I can do is get it sharp enough that it'll shave without any downward pressure applied to the blade. This is definitely sharp enough for me. It's somewhere between shaving sharp and hair-popping sharp.

For those who don't frequent BladeForums, here's a description Liko gave for the progressive levels of sharpness. You can see why I haven't tried the test for &quot;scary sharp&quot; <img src="smile.gif" width=15 height=15 align=middle border=0>


Sharp - Edge is able to cut through most everyday materials without undue force or sawing back and forth needed.

Shaving Sharp - Edge is able to shave hair without also scraping skin flakes off.

Hair-popping Sharp - Edge is able to grab hairs and cut them without the knife touching the skin. It feels like the hairs are popping out of the skin when the edge grabs and pulls them.

Scary Sharp - Edge will cut into human skin under just the pressure of its own weight. This is, in most cases, too sharp, as a knife this sharp is dangerous. One mistake or slip could easily send the knife to the bone.

Crispy Sharp - Knife has been sharpened at a 20 degree inclusive bevel, starting with the medium, then going to the fine, then the ultra-fine, all without rolling the edge. The edge is then stropped to finely polish it. This edge will go through skin like a hot knife through butter, but give it cardboard or wood, and it'll choke.

Wow, I'm a quoted poster now... *gets warm fuzzies*. I'd like to know what &quot;crispy sharp&quot; is from Sal's mouth. My description of it was just the sharpest skin-cutting edge I could think of.
