Leathercraft can be dangerous when not using well the tools or because we are not concentrated. I just did like you with my awl, several times and it's often when I'm thinking of something else or listening to someone talking to me :(
When I was learning leathercraft, one of the student badly cut her hand with the skiving knife (It was quite traumatic for me so even if I used it well, I wouldn't use it anymore for a while and prefered use the skiving machine). Another one slightly peeled his finger with the sanding machine because he wasn't aware of what he was doing.
Now, I'm practicing from home and I don't have these machines anymore, I have to use the skiving knife again and finally, It's alright. I use it with all precautions taught by our teacher and it's fine.
