Hi everyone - - I've had a Sharpmaker for awhile, but just recently bought my first Spyderco folder, a Centofante IV which has a Wharncliffe style blade. Could you please tell me the angle to use on my Sharpmaker when sharpening this knife ? (And perhaps comment generally on the angle used for various Spyderco knives - is it different between models?) Thanks in advance for your help. Regards, - - -
 
Ideally 30 degrees but the grind probably isn't that acute. Use a magic marker or sharpie to see where the edge is. You will probably have to use the 40 degrees without a complete rebeveling.
 
The goal on Spyderco edge bevels is 30 degrees inclusive. They are done by hand on a belt grinder, so they will vary a bit. The VG-10 of the Centofante IV can certainly take that angle without problems, especially if you stick to the light to moderate tasks the Cento was designed for. For heavier use, the forty degree inclusive edge will be more durable.

Many folks use the thirty degree setting to set what is called a back bevel, or relief bevel, to thin out the edge. They then use the forty degree setting to put on a microbevel, so when they touch up, all they are working on is a very small area of the bevel right at the edge.
 
Thank you, that gives me a good place to start. As you mentioned, the Centofante IV blade seems designed for light/moderate tasks & that's what I got it for. I will try the 30 degree setting on the Sharpmaker to start out with. Regards, - -
 
The Cent 4 is perhaps my favorite Spyderco for EDC. It is just such a well thought out knife. I use a Lansky so I can't help you on the Sharpmaker but I suggest going as much as 20 degrees. It sounds like a lot but it is a thin blade and will only help to slice things.

As you know because you have one, the Cent 4 is thin and light with a thin blade. It makes you think that it is weak but it isn't. There have been times when I have used my Cent 4 much harder than I would have wanted only because it was the only knife I had on me at the time. That is one thing about the Cent 4, it WILL be on you when you need it. Your Manix may do a better job at heavy cutting chores but only if it is with you. A Cent 4 in the pocket is worth more than Manix at home in the drawer.

My point is, it is a very strong knife despite it appearance of weakness. Use it hard and I think you will find that it can take. There is just something about FRN and VG-10 that wants to work!

Thanks guys for your comments. The Centofante IV is only my 2nd Spyderco. (Trying to find a Spyder Card that I bought back in 2001 and misplaced in my house somewhere. And, have a Mini-Manix on the way.) - - - I am extremely impressed by the Cento 4. What a great knife - - so light you don't even notice carrying it, but does great work. I find that I'm using it more than any of my other knives right now. I'm definitely picking up another one. All the best, - - -
