Hi Ana, First, I would remove the knife and the knife holder and clean everything from even the smallest debris. After it is all spotless, I would put it together, make sure all screws are tight and try it again. More likely this will solve the problem.
Second - look carefully at the knife holder. We have had a problem with a notched knife holder that had to be polished patiently with fine sand paper for metal (on flat surface) until we removed the damage/notch from it and got it to be very smooth again. Hope this helps Michelle USC Keck School of Medicine _______________________________________________ Histonet mailing list Histonet@lists.utsouthwestern.edu http://lists.utsouthwestern.edu/mailman/listinfo/histonet
