FINALLY!!!

Here are the pictures of knives 1-7 at 20x (8mm wide x 6cm wide) and 200x (2.5cm wide x 1cm high). 400x will be next, but this should start the ball rolling

Before posting begins, I'd like to say just how impressed I am with all of these edges. They are all incredibly sharp, and my hat is off to all the entries. It takes a lot of guts to show your work on this forum, and I was not let down at all . I have learned a lot already.

Next, there is a ton of things to DISCUSS and LEARN from these pictures. Anyone who simply compares the edges and declares a "winner" is missing the purpose of this friendly competition. For those who think they can do better, I welcome you to put your money where your mouth is, and PM me for my address to send me a knife. It will only make for an even more comprehensive study.

OK. About the pictures:

All the edges were mirrors, and I tried to catch the scratches at 20x. I also tried to catch all the 200x photos in a white light. All the blues and reds reflect too much and don't give a clear picture. As nothing this close looks good, the white light really brings out the contrasting scratches. Some edges were very difficult to get the right lighting, so I did the best I could, so there are inconsistencies in the angle positions which may make some bevels look wider or more narrow on the same knife.

I did not change anything with the photos. Except for a couple that were cropped to remove the empty space so they would fit better into the page, they are untouched. The size of each picture, cropped or not, is the same. (IOW, I cropped the picture after I got it to the same size as the others). Dimensions were discussed in the other thread, and are on the top of each picture page. You may need to do some ducking and weaving around your screen to get some of the pictures in the right point of view. I tried to ficus more on the edge of the edge rather than the bevel.

OK, so here we go:

Knife #1 20x


Knife #1 200x

Great pics, but the lighting plays with the mind & eyes in attempting to choose the better looking edge??

Wow. Nice pics. This may be a stupid question, but are all those edges micro-bevels so far?

If they are and if a micro bevel creates a sharper edge, I wonder if I can produce that on my belt sanders...?

But anyway, those are some awesome pics of some really nice looking edges!

Thank you for all the effort you're putting into this competition!

DJ - all the knives show signs of thinning, and then at least a primary bevel (I wouldn't call that a microbevel in this case).

However, there are obviously secondary and even tertiary bevels on some of the knives. Most notable are knives #1 with a tapering double bevel, and especially #3 - with a triple bevel.

Less noticeable are #5, which shows signs of stropping. #4 shows signs of staged angles, but they are blended extremely well, giving it a convexed look.

#2 and #7 look free handed. #6 is the only one with a single bevel, but it was thinned a great deal with a belt sander first.

Very interesting observations so far. I wonder what folks will say after the fact about techniques and philosophies used.

I usually go 1k, 2k, 4k, 6k, 10k, 0.5 micron, 0.3 micron. On the knife i sent i did 1k, 2k, 4k, 10k, 0.3 micron. I skipped 6k and 0.5 micron to leave a little toothy edge since the test will be relatively short. As you can see its pretty scrached up...
