Guys: To answer your questions on refinishing and sharpening.
For the original owner, it's lifetime resharpening and refinishing, for free (owner pays shipping both ways) Although my warranty is for the original owner, generally I don't even ask. Sometimes, I might ask a second owner for $10 or so, depending on the condition of the blade.
Cliff for sharpening, my advice is this:
Take a piece of 1/2" wide adhesive tape and cover the top of the grind line with it, the length of the blade. When you lay the knife down on the stone, the adhesive tape will keep the scuffing you refer to down to a minimum. It will also increase the bevel angle very slightly, perhaps one degree, and ensure that you work right down on the very edge. You want to try for very light contact on the tape, or you may peel it off by accident.
I like the fine or ultra fine Spyderco stones. I have about $300 (OUCH!) of Japanese waterstones, and, I can't see any real difference/advantage. My knives tend to gouge the waterstones pretty easily (satisfied grin
)
BTW, I sharpen only the ground side, maybe 8 good strokes, then maybe make one really light pass on the flat side, at a VERY low angle to the stone.
Stropping on an old belt is key. No, I don't sharpen this way in my shop, but, I just talked with two customers tonight who have followed my advice and get good results with the above method.
One last thing-if the knife has a Tanto point, sharpen the point separately from the main bevel-you have to pick the butt end of the knife really high off the stone to get the angle right, and most people cannot perform the combined motion consistently.
Hope this helps--
Stay Sharp,
