Need help on High 5 prop Q

[Argonaut]

Any prop experts out there ?
Picked up 2 2nd hand props ….. both are Stainless Steel High 5 props ….
Neither has any dings or damage, but noticed that they both have what I would class as a slight straight portion on the leading edge of each blade.
I have never had that on my previous stainless props – but never had a High 5 before.

I would have thought that wear this even on all 5 blades on both props is unlikely, but thought I would check.
If you have a High take a look at the pictures I have uploaded and let me know if your prop has same ‘slight flattening’
