I gained an appreciation for how precise/sharp our tools are when I learned microtomy. If you so much as touch the cutting edge with anything outside of its intended use it messes up that area of the blade instantly. Same goes for a nice pair of chef’s knives.
I’ve had 2 ACL reconstructions, but the first knee surgery I had was a scope. The surgeon allowed me to stay awake and it was freaking awesome to watch the little grinder and vacuum at work!
Its crazy how crude all of our tools look at this magnification.
Some medical tools look crude even at regular size… they don’t call orthopedics bone carpenters for nothing!
I’ve started calling folks taking X-rays the bone paparazzi.
I guess that’s better than calling neurosurgeons spaghetti artists

It actually looks a LOT smoother and sharper than I expected. Look at microscope photos of razors and knives and they look like chewed up chisels.
I believe it’s damaged by piercing the skin, it’s pristine before.
Yet it emphasizes just how precisely tiny the tip of the needle is.
for this magnification it is actually pretty smooth
source: I have used an SEM at my university and never saw something this smooth even at higher magnifications
of course I didn’t look at medical tools but this shows that they are crafted very precisely
