Do you look dumb too?

Hahaha. Funny stuff! Thanks I needed a laugh

Remember this pic?

This is a picture taken through a microscope of a hair being shaved. Not shaving hair but A hair.
Talk about shaving hair.

The knife is a Halo. The pic is by a forensic specialist who sure knows how to sharpen knives.

I am also guilty my left arm looks like I got into a fight with a Norelco. I also get teased.
 
After looking like I have left arm mange, I have decided to try areas that are not visible. Not a bad idea, until my annual physical... Now the Doc thinks I have some exotic mange that affects left arm and both ankles. We need a name for this phenomenon. Bi-lateral Bladus sharptesting?
 
Real men shave the hair where the public can't see it, just make sure you've washed all the honing oil off your hands first!

I'm pretty much have hairless arms (?), so I've taken to slicing a sheet of copy paper, If I feel little resistance when slicing, I know the knife is hair popping sharp. It beats shaving my legs.
 
tschlosser- Great thread! Just be carefull when shaving your personal "stuff"

I have also used the technique told by mgkrame and it suits me great, it's too bloody cold to be shaving off hairs here

Absolutely (great topic): at least my arm hair is light in color. I'm thinking about switching to my thighs (I may have to when all the ahir is gone form my arms!!!!).
 
Hey Guys,
I would think twice before you try shaving hair off your legs. Last summer I thought, what the heck, and I did it. Took all the hair off on the inside part of my ankle up almost to my calves. I have hairy legs and walking around in shorts (it was summer, DUH!!), I got numerous stares at the bald part on my leg. No one was nice enough to let me know about it like that old lady. Took 2 weeks for the hair to grow back!
Just a thought...
 
I've used sometimes a NAIL test that's DIFFERENT from what Sal criticized. The angle of the blade is 90 degrees, and the actual test, whether the edge STICKS to the nail, when drawn across it very lightly.

Have heard many Puukko-users do something like that, too (with very acute sharpening angles).

Of course there are variables, which may distort the results, like the coarsity of the finish of the edge (a coarse edge drags, but does not really stick; uneven edges are, of course, not counted), and the toughness of the nail's surface (thumbnails seem to be harder, but oddly, the toughness of my nail surfaces seems to vary a bit with time due to don't-know-what).

And when your nails are full of scratches... Well, you do have friends and colleagues, don't you? What a way to start a conversation!

Now let me get this straight, just about all of us do it and we know it's dumb. OK, at least me and my mangy arm aren't alone.

I want to thank each and every one of you for responding as my wife now knows that I suffer from a disease, not just weirdness.

I've been trying out various thumbnail tests and I've used a lot of paper the last few days. I'm willing to concede that I can survive without shaving my arms, but it does call to me. The first step of recovery is recognizing you have a problem, and if I'm not mistaken we've helped a lot of people in the past few days. Thanks again.

I would venture a SWAG that shaving hair off your arm as a test of sharpness is mostly done for the convenience factor, I mean, it's right there, just asking for it

One test I came up with, mostly out of boredom was to pull a stray hair out of my noggin, lay it flat and lightly drag the edge across it to see if the knife could shave the cuticle off the hair without severing it. Well, 2 of the 3 carry knives I tried it with passed...the third?...Well, it was an excuse to sharpen something

Try shaving a long strip that runs the length of your forearm along the edge of the hairy part of your arm. It is more natural looking and can really only be detected by comparing with your other arm.

Alternatively, hold up a stack of newspaper, 2-4 sheets thick, in front of you. Use only one finger and one thumb. Cut downwards from the top (horizontal) edge of the paper. Use a smooth motion similar to when using the Spyderco-type sharpener. Start the cut at a floppy part of the paper - a few inches away from where you are holding it.

A really sharp knife will "bite in" without sliding or skipping along the edge of the newspaper. The paper should be cut cleanly, not torn. There may be fine fibers sticking out from the cleanly cut edges of the paper. A "scary sharp" knife will cut the fibers leaving no "fuzz" along the cut.

Hope this helps
 
I stopped shaving my arms because it looked like I had a disease.

Until today, I simply felt the edge with the various calluses on my hands and fingers, figuring I meant for my knives to cut flesh, anyway.
If it feels dangerous, I consider that sharp.

But having read now about paper, I have pulled out all my "sharp" knives and tried them on paper.
I found that they cut best if I present the blade at a 45 degree angle and cut across, at least on the brand of copy paper I presently use.

Some of the knives cut paper much better than others, which raises the question of knives cutting one material well and another not well.

My leatherman and Greco each have materials they will cut easily and materials they will not cut.
I attributed it to "grain", or the scale of micro-serrations favoring one material over another, and especially see the difference when cutting rubber-like plastics, hose, etc.
 
Any more I only test the blade on my arm hair if I already know it is "scarry sharp" and just want to see the hair fly all over the place with the lightest touch.

I use the nail trick to know if I'm getting in the right direction and have developed a fairly good "feel" with my thumb pad to feel if the edge is clean and the burr removed.

I usually keep a stack of Post-Its on the table as a test too, I've found that a well sharpened pocket-knife will cleanly cut paper without any drag.

With the supersharp knifes (like Hartsfield's) I can take a standard business card, lay if flat on a table and "shave" curls of paper from it laterally, kind of like "milling" it.

Just dont shave the upperpart of the arm. I check for sharpnes on the underside of my arm just behind the clock

I have a related problem. Most of the furniture in my room is topped with 1x16 boards, and the edges have just about been chamfored with knives and chisels. I've even carved holes in the top of my desk while waiting on the phone.
