Thread: Looking at the edge

Man, this thread has been disappointing. I thought I'd roll a grenade into the room and see who screams with this post. Apparently the post was not all that outrageous after all.

I have noticed the same thing and you put it very well. Perfect is preferred but often times unnecessary. The only thing I need is a smooth comfortable shave that results in faceturbating. Carry on.

I looked at an edge under 1000 magnification.

You would not think it would cut anything!

You have to keep the size of the “chip” in perspective, depending on your magnification. Next time you see a micro chip, pluck a hair and lay it next to the chip to see how large the chip really is.

I too remove all microchips. It is true that you can thin an edge so much that it will fail early on, So, the steel plays a big part.

While one could shave with a microchip, the chip is a source of further failure, and will only get larger as the steel flexes, stropping. A chip is a chip and chipped for a reason.

When there is rust on a razor, especially at the bevel, the steel is always suspect and susceptible to crumbling, if so you will have to remove some steel to get to good solid steel, joint the edge and re-set it in about 20 laps.

Can't argue that one bit. OTH it gave me my usual 4 pass shave without discomfort as well as any other blade I have. So, for me it is SHAVING.

Here is some perspective. These photos are a part of a stropping wear study. The initial edge is from a Shinden Asagi. That hone was chosen because the serrations and striations of the kasumi finish make it easier to see the effects of the stropping. At first glance, it looks pretty rough.



But, if you compare it with what you are trying to cut, things make a lot more sense.



This is one of my chin whiskers at the same magnification.

As I mentioned earlier, all this is for research. If you don't understand what is going on, it will drive you nuts. In daily use, an Optivisor or loupe is just fine.

My best loupe is a 7x Hastings triplet.

I hope anyone reading this thread realizes that a diopter value of 7 equates to a magnification power of 2.75X. Far less than a 10X loupe.

I use a 30x loupe, but I don’t really understand why I am seeing anyway

I have another question guy’s sigh.

What is Devils Spit?
