To me the whole thread covers the whole spectrum of sharpening, from the cost effective "scarey sharp" method of using fine grits of W/D sandpaper and cardboard to a fair representation of expensive water stone.
All I can add is that there was an omission of "deburring" wheels, not so far removed from Cratex. I find them useful in rehabbing the "rough shape mildly surface rusted chisels and carving tools prior to investing time to try and establish a keen edge. I do like to be frugal, and odd sharpening gizmos do tend t0 be on the pricey sidel
At gsales, nothing differentiates deburring wheels from normal grinding stones except for three characteristics..
1. They are lighter than what you would expect
2, They dont have a ring to them (which with a normal girding wheel would indicate a fracture and you should avoid them)
3 they feel a tad rubbery.
One of my local industrial suppliers stocks em and sells them at 150 a pop, just a tad more than normal grinding wheels.
In the last 6 mos, since I've been tuned into what thy are, I've picked up three of em for about 5 bucks each, simply because they look like normal used grinding wheels, which ain't worth more than a couple of bucks if that much!
The sellers were likely laughing at me for buying them at 5 bucks, but I had the last laugh eh?
BTW, I don't mount them on a grinder, just mount them on an arbor and chuck em in the drill press (nice slow speed)
Other weird sh*t around the sharpening bench is a jool too (another garage sale find-just another piece of plastic crap to some folks I guess with a bunch of attachments.) And a barbers razor strop. Diamond stones of various grits too!
I must confess I ventured into the "carvers" sharp spectrum a while back and while most of my day ti day sharpening is less demanding, It is a ramp up the off-the-shelf items from the normal chisel and plane blade requirements for day to day work, I grok that aspect of the sharpening world entirely now! Outside of sharpening stones, polishing compounds, another item which seems to NOT be commonly mentioned in discussions of sharpening methodology and tools is a simple dissecting microscope. Which lets you see real close up what the edge looks like after all yer efforts.
It's not a OCD tool, just helps you ID and will hopefully understand and solve sharpening problems (does yer buffing wheel round off the edge or not? is my TS blade still sharp ?) On kijiji or craigslist 20-50 bucks will do the trick. Some of my watch/clock maker friends actually have one of these mounted over their precision lathe
