I don’t like the fact that hard medals wear the teeth down so quickly. I use the blades for multiple surfaces from copper to hard steel and certain types of stone masonry. The only good thing I can say is that there are 100 blades and I will use them all but won’t buy the same brand again.excellent saw unbeatable priceMax Power, it's the saw whose name you'd love to touchBut you mustn't touch, it's name sounds good in your earBut when you say it, you mustn't fear'Cause it's name can be said by anyone.I found this to be the perfect hacksaw for our home tool collection. Well made with a comfortable handle and somewhat shorter in height than most hacksaws. I find this gives the tool a more controlled rigidity when in use not to mention a better fit in my tool storage box. The supplied metal/wood cutting blade is easily swapped with any 12" hacksaw blade that attaches using holes drilled into each end of the blade. The tightening mechanism is easy to operate and my only caveat is that the blade mounting pegs should be metal instead of plastic which may be a deterrent if you need it for everyday professional use. Other than that a great value for the cost.Was not crazy about the blade that was on the hacksaw, as it broke very quickly. Thank goodness I had purchased additional blades and they are much more durable. What I like about this hacksaw is the ease of changing the blade, as well as how well it is to work with. Great purchase!This saw feels solid, the blade can be tightened well, but only has two blade angles. One is straight down, which I use the most time; the another is 45 degree tilt blade positon, which is useless for me. No 90 degree blade position. So 4 star.Not exactly what I had in mind. But it is only a hacksaw, and will do the job just fine.They blade it came with seemed cheap.Exactly as described. Good ration quality/price. Couldn't ask for more. Thanks
