Yeah, you can but.... As has been mentioned, they're big and ungainly and difficult to get into tight spots. And if it's your Mom's (or your wife's) iron, you'll most likely ruin it and tick someone off!

You can buy these things used at RC auctions or swap shops for around $5. I should have grabbed the 2 I saw being given away at the auction yesterday, but I already have two regular irons and two trim irons.
