Kinda a stupid question I know but I have a really cheap junior hacksaw, the kind that is just a metal frame, like this: http://www.foxdiy.co.uk/view_product.php?product=TL326 but can't for the life of me get the new blade to go in. I have tried squeezing the handle together with a pair of pliers but that still didn't bring the two ends close enough together to be able to fit the blade. Any help appreciated!
