I was testing my Stretch when I got the urge to compare it to the Daddy of all my Spydies: my M390 Millie.

My M390 got a very thin factory edge and I was able to maintain mainly by stropping on leather. it cuts like a laser.
Compared to my new Stretch the difference was hug. The C90 with a thinner blade got a thick edge. I was not able to measure it but it’s a good 40°…

So I have decided to convex the edge of that thin full flat ground blade, even if ZDP 189 is a bear to sharp.
My first step has been with Lansky diamond pads for eliminating the shoulder of the thick edge. I was able to do it with out scratch the flat of the blade.
Then I have stropped the blade on leather with white compound until I got a mirror finish.

The performance is night and day. I will check now how the ZDP189 convexed edge will behave, but I had applied the same treatment with a Michael Walker which is now used every week end as a skinning knife. Anyway, I have been able to cut through a plastic bottle’s butt is one pushcut. My C90CF is now laser sharp. As sharp as my Gayle Bradley but certainly not as strong. We will check that later.

Talking about sharpness. The jimping is really sharp and hurting the hand. Again diamonds has given me the possibility to eliminate those teeths. The new version of the Stretch got better jimping, the same as those applied on the choil.

So now, my Stretch is ready for more tests, tonight it will tomatoes slicing time.

Conclusion in the Part 3.

Oh yes it cuts…
