Uh, no. You do not know sharp until you try one of Pohan's blades.

That wasn't a sharpness demonstration? I just posted it because it's the best example of push cutting paper I had already uploaded on that site.

Besides, if you look at my other videos you can see me whittle individual pieces of hair multiple times with ease.
 
I have no doubt you know a sharp edge when you feel one, Vivi. So until you have felt how an edge performs, is their you can determine, without doubt, that a knife is sharp? :)

Oh and Pohan, you got some messages sent your way....;)

Cutting the paper by pushing the blade straight into it, not using a draw cut or slice to get through it. I make the distinction because slicing paper can be done very, very easily. Push cutting paper takes a bit more of an edge, though it's still easy.

This isn't the best example but in the end of this video I'm using more of a push cut, though there is some slice to it since I was going fast. The knife catches a few times too because the blade was chipped from being batoned through co-ax cable, but as you can see the rest of the edge cut just fine after hacking at a wooden board and being batoned through some scrap wood.

So basically, put the edge of the knife on the paper say at 90' degrees and cut downwards without starting out farther away like i did in the FIRST video. okay :D Easy enough.

Yep, just straight into the paper without sliding the edge forward or back. The knife in your video looks like it should do it just fine.

If you don't doubt that I "know a sharp edge when I feel one," why would you follow up that statement with is there a way I can determine without a doubt whether or not a knife is sharp? That sounds contradictory and I'm not really sure what you're even asking, sorry. I run my thumb across the edge to check sharpness and it's worked for me. For more specific measurements I use a method similar to Vasilli's thread cutting.

I was merely trying to say that judging the sharpness of a knife, ultimately, should come from first hand experience.

It is my opinion that seemingly judging Pohans knife by a simple video test may not have been entirely fair.
 
Ah, I see. I did not mean to imply I knew how sharp the knife was, only that a sharp knife should easily push cut paper, that slicing paper is pretty low on the list of "sharpness feats" so to speak. I can slice paper with knives that won't shave arm hair, for example.

This is to say nothing of the ergos, balance, materials etc. of the knife. Not trying to pass judgment on it.
 
Absolutely correct:

"slicing paper is pretty low on the list of "sharpness feats" so to speak. I can slice paper with knives that won't shave arm hair, for example."

It certainly doesn't prove anything to a knifenut; isn't that what this place is about?

That's why the sharpening guy at the state fair puts that rough edge on and then demonstrate how sharp it is by cutting paper with a slice cut. At least the state fair boys use newspaper, which is a little harder to cut than regular bond. At the state fair when customers are few, they do the big demonstration by slicing fruit, vegtables, wood, and then end with the newspaper cut. Now the sharpening boys at the knife shows use that final polish wheel, they usually use the newspaper trick, but with slices and usually a final push cut.

Either way, any knife sharpener at a state fair can get any knife as sharp as the one in that video in less than 3 minutes, so the video doesn't demonstrate much about the knife or the edge. Plus, it's even easier to get that kind of slicing power from a chisel ground edge.

I've seen a master smith demonstrate their edges with fine rice cigarette, with push cuts at various points at the edge to demonstrate sharpness and uniformity. Wouldn't that be a slightly better demonstration of an edge's initial sharpness?

Yep, Pohan's knives certainly are not sharp enough....:rolleyes:

By the way, how many zero ground chisel edged knives do you own?

Gotcha! :D
 
Never said the knives weren't sharp, just that the test was less than useful. Any knife will pass that test, as is proven at 50 state fairs and countless gun and knife shows each year.

I have owned two zero ground chisel knives. One by Sean Perkins and one by Newt Livesay. Got rid of the Livesay, it was crap but loved the Perkins. Its a small knife, about 1 1/2" blade and 2" handle, about 1/8" thick and is in A1 steel. Its about the same size as a Buck Hartsook. Use it every day to open mail, cut hang nails, sewing, etc. Sits on a magnet attached to the lamp next to the TV chair ready for use at any time. I like the chisel grind, especially in a small knife. The Livesay was bigger, and I did not like the chisel grind for a larger blade.

Never said Leu's knives suck. I've read a lot of good things about the knives. But some of the comments sound like hype. But I know, from the knives I own, that A1 is a good steel (that's what Leu uses right?), that can be made good and hard, and it is strong. That's why I challenged the thought that a simple paper cutting test, using regular bond paper, with a chisel ground tool steel blade, was a real test.

I also asked why Leu is called a master, I didn't realize it was a joke. All this time I though he was a master smith. However, I checked out his website and it appears he's a stock removal guy.
