Query: Many problems with Henckels shears

I'm on my second pair of these shears. The first pair was inherited when I got married, the second was a gift to replace the first (due to the plastic catch falling out and the blades rusting).In less than one year, the second pair is almost unusable. The coil that is supposed to spring them back into the open position has lost its bounce due to rust inside the coil. The safety catch works too well - it catches automatically almost every time I close the shears. This is extremely annoying when clipping through a chicken breast. I have to stop on every other cut to re-open the shears. Finally, the shears cannot be separated for full cleaning.NOTE that this model has a different catch mechanism, but the coil does look the same.
