"I bought this in store on impulse did not have the benefit of reading reviews online. If I had I probably wouldn't have bought it.
Regarding blades coming loose - I can understand why people are frustrated about that. Irwin provided a philips screw with the saw. Philips are really limited in their torque. I found that I could pull the blade out of it's "pincher" by hand. I replaced the Phillips with a m4 hex bolt. Hex bolts can be torqued up higher and the blade stays put. Having said that I only used it on acrylic & wood - will cut a few bolts in the weekend and update the review if performance is bad,
I could have returned it but to be honest there aren't any other substitutes for this product out there, this is the only "handysaw" of it's type other than a draper one - so you have to make the best of what you have."
"Like every other review says. This is a great idea for a tool but it just does not work. The screw does not grip the blade at all and so slides forward and backwards not allowing you to cut anything. Good job I tried it in the back of the van before I left the car park so could get a refund straight away and not waste time."
"At first use the blade slowly slid back through the handle. This was despite the single securing screw being so tight that it could not be unscrewed. I managed to destroy the cross head slots in the screw in the the process."
