All of the above mentioned in the title is types of strokes, am I correct? Does this imply that all of these, if they were to occur from open head injury, would definitely cause stroke symptoms? If yes, even the slightest cut to actual brain tissue causing the least amount of blood to leak possible, would still cause stroke symptoms since it logically also has to pass through the other intracranial layers covering the brain tissue?

This is still in relation to the "pointy/edgy object skull penetration" matter.

(sorry, back for this one, since I figured this site would be better equipped with the knowledge to respond with more thorough answers).

Minimac,

Your "pointy/edgy object skull penetration" did not cause a stroke. You did not cause an impact that traumatized the brain and vascular structure.

First, you did not penetrate the skull. Second, you barely scraped the outer layer of skin.

You did not have an open brain injury nor a penetrating brain injury. Neither of those would cause a stroke even though they would cause damage to brain tissue.

A stroke happens when the skull has not been penetrated but somehow, the vascular stricture has been damaged by trauma or high blood pressure or clogged by a blood clot or plaque.

Anxiety can cause a stroke by causing high blood pressure. This is one of the reasons anxiety needs to be treated and resolved.

Well I dunno, my skin leaked a little blood from the impact, mostly when pressure was applied. Probably equal to two or three blood drops, so well, I guess and hope it only was the very outer layer that only actually was damaged a tiny bit. The wound was so small that the only thing that makes it noticeable by the naked eye was the blood flowing out at the time. After an hour or two there was no sign of damage at point of impact.

Minimac,

If you are skeptical of our answers, why do you ask the questions ? We are trying to help you with sound information. You say "Well, I dunno." We do know. You did not cause a stroke or any kind of penetrating head injury. I have probably done more damage shaving. I can bleed for hours with blood dripping down my face if I don't use a styptic pencil to help clotting, and that is just from capillary oozing.

So, please accept our answers. We want the best for you.
