Review title: Poor head design
Product review: Since the blade is built to be replaceable it is held into place via a slot in the head of the tool. This is all fine and good in theory, but in practice I had lots of gunk (glue, flooring, tile chips) get jammed in between the blade and the head. This causes the blade to turn into a parabola and thus gouge your floors if you don't notice it. I tried to remove the gunk by removing the blade and cleaning it out, but the present of additional material made the fit to tight and I was unable to open the head (2 screws). I stripped one screw, hacksawed a new phillips slot into it, and stripped that. When I returned it to the hardware store where I purchased it they told me that this was not the first time they had seen this same problem.
