I replace my silky blade 3 or 4 times a year. I resharpen them 3 or 4 times before replaceing them. When I retire the hand saw blade i put it in a vice, and brake the handle off with a hammer and use it on a pole saw. A replacement blade is around 65.00 a small price to pay to have such a killer hand saw.
If your getting a year out of them, it was probably time for a new one anyway.
I broke one in the cut one time. With steel, be it knifes or saw blades, you have a choice between a brittle hard blade that holds an edge, or one that'll flex some or bend, but doesn't hold an edge. Try not to drop your next one. And even the impulsed harden saws are getting a little dull after a year if you use it much.
