"Use these regularly, although hardly ever as a screwdriver. They make great levers and use with a hammer means you can split most things. They're strong and at a fiver great value. They do break now and then - but only when being used in extreme circumstances - but a new set is cheap enough. Have used for years now and they (maintenance at large site) are a must have in my tool bag"
"Really strong screwdrivers. Can be leavered with a wrench on the square shaft to give it more turning power, Can also be hit on the top of the handle without breaking it as the steel shaft passes completley tho' the handle."
"I paid £5. Reviewers who liked these have read the description but not used them. They failed for me on the first use under heavy load so, 'no', you can't hammer them nor spanner them. I have one with a broken tip and another with a twisted shaft. Seems like I can't get away from spending way more on screwdrivers."
