I am looking for an explanation about a simple physics phenomen.
When washing plates and ustensils, I would manipulate knives and, from times to times, would cut myself a bit. Does it matter if your hands are wet or dry and what does the water do on the surface of the skin that can influence the blade to make or not an incision in your skin.
My remark is that water soften your skin and makes it more fragile therefore it should be easyer to cut it. My hypothesis is that by making it soft, the water protects the skin by filling holes and makes the skin more difficult to be cut since the water molecules will have a tendency to deflect the blade. What's the real explanation of that daily experience ? What changes with other substances ? Which makes it easyer or thougher to cut ?
P.S: Sorry if this is posted on the wrong forum
