Reachout is absolutely correct. We still call it lead, but pencils in the US no longer have lead, they have graphite. Don't worry about tetanus. That comes from things like rusty metal. Infection would be a concern, though. If you can't find the smelly stuff Reachout mentioned, you can also try hot compresses (not too hot, you don't want to burn him!). They'll help soften and loosen the skin so it will be easier to get a small particle out. That's how I've always gotten my kids splinters out. Put a little antibiotic on afterwards.
Glad he missed his eye!
Take care,
