guys I need to know what's a good part of the body to slice to get blood for a blood ritual. I'm thinking shins because I've done that a lot by accident while shaving working or hiking but I'm open to recommendations
i think veins probably. you can find blood in there
Arteries are even better. They want nothing more than to provide blood.
If you're not looking to die, however, it depends on how much blood you need.
A drop: needle point to the outside of the middle phalanx on the index finger.
If you need a little bit, but constantly and for a while, a good head gash will go for a long time. The larger the gash, the more blood at a time. Dampen it a little every once in a while to keep it from getting too sticky.
And if you can acquire the equipment, a good medical IV stick (to the veins, per @shosta) can get you anything from a couple tablespoons to pints to be used at your leisure.
