I just want to rant about sharpening for a minute. When I first started out in this hobby (which is about 3 years ago, so you could say I'm still in the beginner's stage), one of the first lessons I learned was the false economy of the so-called "scary sharp" method of sharpening.
(the reason for this rant is a comment someone made about having the "right" tools to do the job, and told the other person to buy more sandpaper...c'mon)
The idea is that you stick sand paper down to a flat surface, say granite or plate glass, and go through progressive grits of paper to get your edge. It sounds good, in fact it sounds great. Some woodworking stores even sell kits to get you started. Ironically, the store that markets that kit hardly caters to hand tool workers. (I won't name them, but their initials are R.O.C.K.L.E.R., a place I now refuse to shop at because of the arrogant staff that look down on beginners and anyone that isn't dropping $5k on the latest laser guided nuclear powered chop saw, seriously it's an effin' chop saw)
So, you get your adhesive or adhesive backed paper and stick it down, grab your honing guide and hone away. You notice that your edge is good enough, and you're happy. Sandpaper isn't that expensive (so you think) in small quantities. As you use up sandpaper, you buy a little more and keep going. All the time you think, "heck, this is a hell of a lot cheaper than buying a grinder and some waterstones."
You wear out some paper, buy some more, gouge a piece of that trick PSA honing film, buy some more. All the while, you think about all the money you're saving.
Did you really save money? I don't think so. I used this method for only a short period of time before I realized that investing in a couple of quality stones was the way to go.
Look at the price of sandpaper over a year or two of sharpening. Now look at the price of three waterstones, and a bench grinder. You'll notice that the stones and the grinder will cost a bit more. Hence, why you think you're saving money. Take notice of the fact that the stones and grinder will last years, not weeks. In fact, you should buy the grinder no matter which method of sharpening you use. Do you really want to sand a primary bevel on sand paper? I don't care how good you tell me the sandpaper is, it cannot beat a grinding wheel. I have an antique hand crank grinder, and the belt driven suicide grinder. There's not a piece of sandpaper on the planet that can out perform either of them. Minimal investment too. My advice (take it or leave it, I'm no pro) is to spend a few bucks on three stones: 1000 grit, 4000 grit, 8000 grit, and a bench grinder. You'll need a flattening stone too. You'll make the salesperson at Woodcraft smile, and you'll smile knowing that your sharpening is being done right. You'll smile even more when you see that you're not being nickel and dimed to death trying to get a good edge.
