Thread: Hanging hair test.. How sharp is sharp?

Not sure where to drop this one so here it goes...

So I usually test a piece of my wifes hair from her brush after stropping preshave - as a verification that my 40 laps has been done well and good. Thing is, I notice that the hair only cuts with the follicle on the side being cut off. Additionally - some hairs drop while others are being split. I ran the blade all the way down one hair splitting it in two.. Is this typical expected sharpness or am I not up to par on the sharpness scale?

Yes overall I'm happy with my shaving experience minus a few other items and the blade cuts well when held correctly.

Yeah, you're fine. How the hanging hair test actually works is this: a hair, if you magnify it, looks like a bunch of microscopic scales. Think about a fish, if you run a knife down the side of a fish, from head to tail, the scales will most likely deflect the knife all the way down the side of the fish; but if you run the knife from tail to head, you'll start taking scales off, because the blade gets caught on the edge of the scale and digs in.... same thing happens with a razor and a hair. Always do the test towards the follicle, and it'll work every time; go against it and it's complete luck of the draw.

The HHT always depends on the hair used & the user holding the hair. In my case a splitting hair would indicate a razor not quite there or extreme dexterity on my part.

Except when doing the shave test & arm hair test.

Your face will tell you if your 40 laps on leather has been done well and good, and likewise, it will tell you if they haven't.

The HHT is really a "honer only" sort of game. It doesn't mean a thing for OZ to hone a razor for me, and then I use my hair to test it. All that says is "this razor will cut hair". Now....if I hone my own, and grab my wife's thin hair...and it doesn't cut, time to go back to the hones. I've calibrated her hair and my honing to know that if a razor cuts her hair, its in the ballpark for a shave test. If it doesn't cut, the blade doesn't go anywhere near my face.

If you hone your own....calibrate that test and rock on.

Personally I really only use the HHT on rare occasions nowadays. Particularly after stropping, it is way easier and simpler to waft the edge through my arm hairs about 3-5mm above the skin, depending on how long your arm hairs are I guess. But if you like the HHT that is great, just do as the others have said and work on learning what it is telling you about the expected shave.

Check our Library for a nice explanation of putting the HHT into practice.

I have a routine where I use arm/leg hair for that purpose: for me, the test is not so much whether the razor will grab hair, but how much resistance there is before a hair is cut. I look for none at all. The hair just falls away. It has given me a good dose of razor mange, though. Good thing it's cold out & no one can see the bald patches!

As far as a more traditional HHT, I have yet to find a useful way (for me) of doing that test. As always, YMMV.

i never thought of this, but your right. how accurate is the test then? if you can manage to get muscle memory, and know the angle to catch the "scales" then? I have one razor, that for some reason (i think i narrowed it down to the hardness of the steel) cant do atg. the thing passes the HHT with flying colors, but it is def. not my go to razor because it just doesnt seem to get as sharp as others.

I have a few razors and have been at it for almost 3 years now. Against the advice of most here, I started honing with my first razor. Over time, I have gotten better and found that some of the earlier attempts don't shave quite as well as the more recent ones. I have found that if they are close, but not quite there, a few laps on a barber's hone (I use an 8" Swaty) will bring them up to my current standard.

I have a handful of razors, what i meant was one of them seems to not be able to go ATG. i have a john prince that is really amazing, the thing is like a tank, and gets super sharp. Also one of my TI (celebration crown) its by far my favorite. It just plows through anything effortlessly.
