Would a CNC-machined razor survive if dropped a few feet in a ceramic tub?

That's pretty cool that you have access that kind of equipment.

If anyone wants to donate a stainless steel razor to the cause I'd be happy to run some MIL-STD 4 foot drop tests and do a video for the YouTube channel...

Not as impressive as you think...It's literally just dropping things from a 4-foot height onto a big block of wood.

I guarantee the Menlo Nealon would be just fine.  I have dropped it and it's solid and strong.  it's #billettolast
