Thread: Spyderco

Has anyone here tried using the Spyderco 302uf as a finish hone?

Yes. They do work pretty well at it, also.
Hope this helps.

I'm not sure what Sal means in that link, but I've seen the Spyderco stones rated in several places as follows:

Spyderco stones:
Medium ceramic-----> 20 microns
Fine ceramic--------> 9 microns
Ultrafine ceramic---> 7 microns

I can't find an official source. Here is a thread from KnifeForums on the subject.

Try not to get caught up in the "grit size" wars. Pay attention to the level of sharpness that a hone imparts to the edge, its actual effectiveness. Some people use a Arkansas as a finishing stone but they are rated at between 1200-2000 grit ANSI!. So.... the grit size is mostly important only within a specific manufacturers product line.


Hope this helps,

1200-2000 grit ansi is somewhere around 3000 to 8000 when comparing to waterstones using the Japanese system though.

Great thread. The chart at the top of it actually lists

Med ==> 16 micron
Fine ==> 7 micron
Ultra Fine ==> 3 micron

So who knows? I think Randy makes a good point but it's still nice to be able to compare across vendors.

To directly answer your question, yes, some people use that hone as a finishing hone and like it just fine. I have tried that hone and learned one of its shortcomings. When it is brand new it has "high points" that will chip the edge of your razor. Those have to be worn off by using a spare blade on it. Either a knife or razor. Also be careful of the edges on the hone, same problem and solution.

Ceramic is very hard and does not fracture as readily as a waterstone or natural stone ( Escher, Coticule, Tam O'Shanter, etc.). As a result it is harsher on the razors edge much as diamond hones are.

The good points are that they are not to expensive and will last a long time.
