Being the creature of habit that I am, when my original Fiskars ergonomic cutter started to close itself when I tried to use it because the safety button had worn out, I just went and bought the same one again. (They did change slightly in the thirty years I used the first, but it was mostly cosmetic, from gray to almond). I Figueroa if I got 30 years out of the first one for my ten dollars, why spend more? The new one was a couple dollars more, but I did not mind. If it ain't broke, don't fix it.
