Sharpening tri-stone

Case has a tri stone sharpener that I have been eyeing. It is soft Arkansas stone, black Arkansas stone, and a silicone Carbide. Does anyone have an experience with this? Is this something a beginner who wants to learn how to sharpen blade with a stone should purchase? Any other ideas? :confused:
 
What blade steels are you hoping to sharpen with it? It may or may not work well for you, depending on that.

If you're sharpening simple carbon steels like 1095 and Case's own CV, as well as simpler low-alloy stainless like 420HC (like Case's 'Tru-Sharp'), then it could likely mesh well with those, and could be a good learning tool for the fundamentals of sharpening. If you're hoping to sharpen very wear-resistant steels like D2 or S30V, the Arkansas stones will be very slow at least, and maybe ineffective for any heavy grinding. The SiC (silicon carbide) stone would handle some of the high-wear steels better, for coarser grinding tasks. A hard black Arkansas stone can sometimes be very nice for gentle burnishing/polishing of finished edges, so you might find it somewhat useful for that. I'd say the soft Arkansas stone is likely the most limited of the three in that set, as it may not work too well on the high-wear steels (very slow).

David, thanks for the reply. I would mostly be sharpening 440c, AUS8, 1095 carbon, and I have a damascus of 1095 and 15N20. Sounds like this combination stone could work for me. Any further thoughts on it?

You might be OK with those steels. The SiC stone in the set might be especially appreciated on the 440C; sometimes, depending on the hardness of 440C, it's sometimes slow to grind on Arkansas stones. I learned that the hard way, in trying to re-bevel an older Buck knife in 440C, many years ago. The SiC stone in the set will handle it easily though, and refining & finishing on the other two stones should work out OK. I don't think you'd have too much trouble with the other steels, if any.
