After using the Skinny yesterday on my job I saw that the edge holding capability was not that great. Before I used it I sharpened the blade on a Naniwa 5000 grit stone and stopped it with 2, 1, 0.5 micron until it was scary sharp. I used a 18pds geomety.
I cut some cardboard boxes (double wall +-20), plastic ribbons which hold boxes together and some soft plastic bubble wrap . Afterwards the knife was really dull. Not what I was expecting of CPM-20CV. As seen in the pictures there light reflecting from the edge where the knife is really dull. It rolled a bit and there was a very small chip.
Today I will sharpen it on a 1000 Naniwa stone and then strop the blade. Lets see how this works.
Does some of you observed the same with the CPM-20CV? Do you know how many HRC that Rick Hinderer heat treats this steel?
Here are some pictures
