Spyderco Hap 40, Rex45 and M4 head to head edge retention testing. Let's see how these 3 slug it out

Spyderco Hap 40 Stretch, Rex 45 Para 3 and Manix 2 M4 esge retention testing. Thank you to Travis Young from the Edc brotherhood group on Facebook for loaning me the Stretch, thank you. The Para 3 and Manix belong to me. I put Hap 40 and Rex 45 together since they are analogs. I added M4 after testing and using Rex 45 and the first steel it reminded me of was M4. Head to head battle of tool steels right here.

I'd love to hear your thoughts on all 3 steels if you have used them down below.
