My new addition a Wonderedge Ducky. Just arrived and is mint condition. Going to take it out for a test shave in a couple of minutes.Attachment 290856. Just finished the shave, and it was smooth. Not used to the smaller blades and I'll probably take it to my Coticule to see if I can smooth out the blade more then it is now. Doesn't really need it but the stones are like guns. If you have them you always want to use them.
