i have read in bladeforums among other websites that sebenzas are now being made with perforated washers. i am currently looking for my 3rd large sebenza, but i would like to purchase one with the new washers. i looked all i could lately for a new one, but no luck. if someone could help point me towards one or give me the right date to look for on the certificate that comes with it, i would know what to look for. i hope i am not missing something on bladeforums that answers this question. thanks, jeff
