Cons: It has a SHARP edge, it could be a gun so don't drag it across your palm or anything. should be able to put it in front of her to measure (I needed it for a carburetor adjustment - luckily I was able to get hold of it where I could make that adjustment with a bit of fiddling). Pros: It's durable and made of thick metal. The tags aren't just printed, they're engraved, so if the ink doesn't work you still have tags.
