I just received my Spyderco Ultrafine hone after reading through Joel's thorough post. It did an amazing job of putting a very nice finished edge on a "practice" razor I had acquired. I did not even go to the pasted paddle with Red and Green paste which I have previously used for finishing. The Spyderco is perfectly flat and being made of a synthetic material, should last as long as I can imagine. I'll still use the pasted strop for quick touch ups to refresh a blade between honings and will experiment using it after finishing on the Spyderco.
Anyone try using a pasted strop after finishing on the 12k Spyderco?
Did it improve the razor appreciably?
