Heard different stories about D 2 steel’s hardness if done correctly it’s a good knife steel if not done correctly it’s not so good is there an at home test to determine this like dragging a file across the blade in an inconspicuous place of course.
 
Thanks I’ll just use it and see what happens so far I love it. it’s an OTF cobratec. May be other Chinese brands built just like it but for me it’s a cobratec
 
It may not be D 2 steel but knife for a
Chinese knock off does work at this point and looks well built. Have you handled one and inspected it?

I have. I've handled and owned many OTF's. However, I have never a budget one. Least expensive one I have is an Axial Shift CPM-20CV wharncliffe.

I was well into buying expensive knives when autos became legal in my state, and never purchased a budget one.

I don't have much positive things to say about the D2 I've had. To get it back to from very dull to sharp was honestly not worth the work I put in. It loses its edge too fast in my opinion. However, that was one knife.

However, results always vary. CPM-S35VN is a steel I've experienced large variances with. Some I can get really sharp, some I can't. Edge retention varies as well.

Good luck with the knife, let us know how long it keeps its edge.
 
I’m not going to hold back using it for what every if it crumbs I’ll upgrade I do like the OTF’s so very handy. I take blood thinners so being able to stay away from the blade and using only one hand is some what comforting.
 
Do you have another knife to compare it with?
I used to buy a lot of custom fixed blades and one time I bought a small one on ebay that turned out to be somewhat questionable craftsmanship and material. For a knife that I was willing to use the end result was how good is it at holding an edge. People do these tests by cutting cardboard and if you know how much cardboard you can cut with a blade of known quality, then do the same cutting test with the questionable blade and see how much it cuts. If its cutting performance is sufficient for you then consider that the steel if of sufficient quality and use the knife. In my case I found that the questionable fixed blade wasn't great but it was good enough to show that it had a reasonable steel with reasonable heat treat, considering the price that I paid.
 
I got plenty of cardboard and some knives I trust to be high quality so I’ll compare. Thanks for the good idea.
