Thanks for all your inputs folks.
I used my Perrin PPT a few days ago to unpack some bulky letter packets. These are the shots from that.
Then on another day, I used the Perrin PPT to cut up a King Coconut (KC) and here's two pics from that.
The PPT performed flawlessly on the KC. Ate away through the thick outer skin and glided through the slightly softer inner flesh. Cutting in to the nut was easy too. There was no bending of the blade nor was there any issues after I finished cutting the KC up. Blades still hair shaving sharp.
