Thanks for the detailed reply! Just a few questions though: how coarse and how fine is the combination india stone? I read that the norton india stone is somewhere around 300/500 if I remember correctly. Uh is this fine enough to get a nice sharp knife? :-/ because everyone is suggesting 1k or 6k waterstone. Secondly, is an india stone better than water stone? Or are they just more convenient for a beginner like me because they dont wear out, dont require much prep and are easier to clean? Third, could I sharpen chisels on india stone? Lastly, what is this flexcut on a single paper you speak of?![]()
Thank you.
The combination India stone, once broken in will make an edge in the range of a 1k waterstone off the fine side, actually a bit better depending on the brand of waterstone you're comparing it to. The coarse side will be a bit less rough than a 220-240 grit waterstone. The fine side is more than enough for most edges uses though will need to be further refined for carving, chopping, and shaving. So in my philosophy of "Coarse/Medium/Fine" it takes care of coarse and medium. What makes the India stone so nice is that it requires a shorter learning curve - it is intrinsically more simple to use than a waterstone. Keep in mind, waterstones come in a vast range of hardness, binders, abrasives, and vary in how they break down and what steels they work best on. The abrasive action of a waterstone, which winds up being a mix between grinding and lapping in most cases, takes more hand's on to understand and control. Waterstones will also dish, requiring frequent lapping to restore flatness. This is especially evident when sharpening chisels and plane blades that really need a very flat surface for best results.
The India stone has none of these issues, and if used with a bit of oil will stay in nearly perfect condition forever. They are only at a loss when it comes to the newer high carbide alloys, and some of the very high RC (Rockwell Hardness) carbon steels, though many people have reported good results even on many of these metals if one is patient enough. You are stating this is and will probably never be an issue. Last time I sharpened the blade on my Jack plane, the edge would shave arm hair right off the India stone. A bit of stropping and it was making translucent curls from a warped board.
Is it better than a waterstone? not really. Is it worse? absolutely not. Just different. It has its limitations, but sounds like they are well within your tolerances.
As Brian mentioned, Flexcut Gold is a stropping/honing compound made by the Flexcut company - makers of wood carving knives and accessories. Their compound is high quality. Wrapping a sheet of paper around the coarse side of an India stone and rubbing with a thin layer of compound will allow you to get the "Fine" in the "Coarse/Medium/Fine" simply by stropping the edge. You could also pick up a Spyderco ceramic Fine hone and that will follow the India stone very well in series, but for most of your uses it won't be necessary - stropping on a hard surface with the Flexcut will give you a very fine edge capable of doing some clean woodwork and fine chopping in the kitchen.
There a million options for a beginner's sharpening set-up. This is a good choice IMHO, and there is no shortage of accomplished and even professional sharpening gurus that use this stone. So its a beginners stone that can stay with you for a long time.
