What Is The Point Of Hair Whittling Edges?
March 09, 2019 04:24PM
KnifeGrinders/WootzBlades, a knife sharpener who participates on the BESS Forum and BladeForums, talked about a problem when shipping his customers knives back to them when they were passing an HHT/Hair Whittling edge, the didn't arrive being that sharp. I noticed a similar issue and made a thread about it on this forum. This makes me wonder what is the point of getting a head hair HHT edge when it just goes down to beard hair HHT sharpness? I have noticed this with carbon steel and stainless steel. I plan on asking a few people in the knife world their opinions on the subject, and posting their responses here.

When I sharpen to a certain sharpness, it tells me I've done it right. That extra bit of sharpness only makes a difference in a handful of tasks. However, having a standard and meeting it let's me know my edge wasn't compromised by something I did. It can get a bit ridiculous though. I have started looking for speed in sharpening. 30 minutes of sharpening for 1 hour of work seems a bad trade. 2 minutes of sharpening seems much better. I just glued up new sharpening blocks. The angle control reduces time to sharpen. I can sharpen my Misuzu Bunka one a week or so and it stays at least arm shaving sharp. Once a week, or maybe 2 weeks, I resharpen it. I can sometimes just go to a 4k waterstone but most times a 1k waterstone is required.

That is an excellent point. I think the reason why I would chase initial sharpness
to such high level is about the same.. It didnt come to my mind how to express it,
But you said it well. Same for me.. its sort of an assurance that most was done right
in the process..

me2, JSCT:
Same here. The initial sharpness tells me if I did my job on the stones.

Well, one time this will be good is when you actually want to shave.

I think Oxidation plays a large part in that fast dulling of the edge. barbers typically need to strop before each shave because the fine edge oxidizes so fast

I noticed this on AEB-L but dont know whats the reason and would be interesting to see if I observe the same
on something with extreme corrosion resistance like nitrobe77 or there will be an improvement..
Perhaps whatever I find out I dont think can be considered accurate..

Interesting discussion. I am contemplating getting 4micron .5 micron and .1 micron as a possible edge for customers, but reading here, now I wonder.

Anything sub 1um in abrasive grain size I consider too fine to be beneficial
for any cutting task I would use a knife for.

I may only strop finer if I am going to shave my face comfortably
perhaps most knives have sharpening angle around 30deg inclusive or higher
and thats not what would I call comfortable shaving..
I shawed whole face w 240mm gyuto because
I saw others to do it and was curious..
for aeb-l I used only nat for razors and plain leather..
