I accidentally cut my hand just now while trying to slice a mango (of all things). My better half gave me a bunch of mangoes to eat and what I’ll do is slice the top off of each one and peel downwards.
However, this particular mango was rather slippery and the knife slipped and I sliced into my right arm instead.
It turns out that the skin at this particular area is actually quite thick, and it took considerable force to make such a deep cut. I think the fact that my knife is about as sharp as a pair of children’s scissors helped, or else it’ll have been much worse. :x
