No, but he'd probably break the tracks off if he did.

He's pretty hard on things. A friend bought him a nice Buck 110 knife for his 14th birthday. It's a pretty sturdy folder, but last I looked at it, it was missing the tip. When I asked what happened to it, he said that he was trying to make a hole in some wood and it broke off. I let him use a cheap machete from Harbor Freight and the blade is now filled with chips and gouges. He can be hard on knives/blades.
