I did the same thing to myself the second time I shaved with a spike. The first time I shaved with a spike it gave me a friendly little slit on my cheek to remind me to pay attention. Since those two times, I haven't cut myself again. I've learned to keep a routine for how I move the blade around my face or under the water. Kind of like when stropping, you get into the habit of holding and moving the blade a certain way.
