Ways to test sharpness?

Well, then we find something with smaller, tougher fibers. Kevlar tissue perhaps?

"This tissue paper made with 10% post-consumer grade Kevlar"

Hmmm...

I am sure there will be a next level at some point, what that would be I have no idea at this point.
 
Very good demonstration in the video! But I do have a question; Is the TP the commercial grade, aka: John Wayne paper or some good quality-soft on the chocolate star type?

I just couldn't resist....:D

I haven't tried nor thought of the TP test. I've always used newspaper and hair on my arms. But now, I'm going to have to give that a shot.

Well, you set the benchmark for me at least. TP slicing sharp is freakishly sharp.

I suppose we would need to get a bunch of ZDP-189 knives ground to 24 degree inclusive and polished to perfection.

Aaaaaaaand....do what with them I do not know. :confused:
 
Is there a commonly purchased material that can offer a consistent, uniform cutting test for all of us striving to obtain the sharpest edges? TP is good, but it depends on the brand, etc. Hair is proven to have it's inconsistencies, as everyone's hair is a different coarseness and thickness, etc. Is there any other material, like fishing line, some sort of commonly purchased thread, maybe some sort of plastic, or anything else that you can think of that can display characteristics when cutting that only the sharpest edges can achieve?

Let's figure this out and get a more consistent measurement of sharpness with our edges...

Sure, that's a great idea. Find a monofillament fishing line rated to have high consistency and universally found in much of the states or even the world. Then some sort of lightweight bottle into which water can be dripped (or obtain a fine weight set). The whole jist is to see how much mass is required to push-cut the line. Repeat a few times for consistency and there you go. Sounds straight forward enough.
 
Murray Carter advovcates his "three finger test" to verify scary sharp.

He free hand sharpens on Japenese Waterstones.

Edge Pro, W.E., Lansky, freehand, all can be effective. It comes down to technique more than equipment. The equipment just makes it either slightly easier or quicker.

Isn't the 3 finger test supposed to be trying to fillet a little skin off three finger tips? I never have been sure about it.

I am even wary of trying that on mine. I guess that on Ankerson's knives, you will fillet your skin.
 
If you do it right, it really works and no, you wont cut yourself if you do it right.

Murray Carter recently won the competition for the sharpest knife in another forum. If he isnt cutting himself with his sharpened knives, Im sure there is nobody on here that needs to worry too much!

You can do it on a razor blade, so if you know the technique, it is safe.
 
I tried my Izula and got through a white phone book page & flimsy receipt with no problems but my wife didn't buy Charmin yhis time around but some cheap junk TP which would just tear if touched with the blade. I need to keep my eye open for the next package of Charmin.

All in all a good showing for the little RAT. :)
 
Well I finally figured out what I've been doing wrong all this time... sharpening at 60 degrees. I left my KMT sharpener set to 30 degrees, I dropped it down to around 23 per side and knives get extremely sharp now. Both my crappy Paraframe and kitchen knife shave with no added pressure, and the kitchen knife even kind of cuts toilet paper. If I could hold it right it probably would cut through the whole thing.
