Query: Do not buy....does NOT hold a charge

This is the second sonic blade I had in one year. I received it for Christmas 2010 and it worked for a short time. I tried using it again later in 2010 and it did not work. Could not muster enough energy to slice even once slice of turkey. I just purchaed this again from Amazon thinking the first one was maybe defective. This one does not hold a charge either. I am in the process of contacting Amazon about returning this. Beware..........this is not a good knife.
