I am one of those terrible people who washes his car about once per year. I figured it was time to give my 14 year old honda a buffing too. My question is about grit sizes of abrasive particles in compounds/polishes. I am an avid knife sharpenner and metal polisher, so have a wide assortment of alum…

@bing My water stones go to 10K (1 mcron) and my compounds, whit i put on strops, go down to 125nm (nano meters) which is about 2,000,000 grit. Although i usually stop at 0.5 micron, so like 35K grit. Correction: compounds go to 25nm which is absurd grit value. very rarely used.

@bing Look at this video: How To Sharpen Knife - Near Perfect Sharpness from A to Z. - YouTube That youtube channel has pretty good info on knife sharpening. It all comes down to practice. For the part relevant to this thread, it is all about grit pyramid. The order of abrasives. Start with coar…

[image] bing: about the highest grit is 3000. For regular work, yes. But for color sanding they can go up to 12,000: [image] Micro-Mesh Finishing Pack Long-lasting "cushioned" finishing papers for a scratch-free mirror shine. But not often used, that’s…

Spent many a year as a chef sharpening knives, and I am using One of these cheapo hand helds, and cause I cant seem to find a steel finish it on the unglazed bottom of some dishes. Mostly use a French knife, works fine for me. [image]

The highest I’ve ever used on a car is 2000 by hand and then rubbing compound with a buffer.

@Barkydog You do not finish knives on a steel. The steel is used to realign the edge if it slightly bends. Most of the time, if the edge is properly sharpened it will never bend. The part that tends to bend is a weak concave edge from dual disk stones or the wire edge which was not properly stropped…

Also want to add is that there are several confusing grit scales… with microns being the common denominator between them. Grit Chart A logarithmic scale has the property of equidistant spacing for any geometric progression, meaning that a ideal stone series will be uniformly spaced. …

Perhaps I do not know as much as you, Your explanation of a sharpening steel is bogus! The sharpening steel removes any burrs and hones the edge, be it ceramic or steel. Just basing my comments on a lifetime of experience and 25 years in the food and beverage industry, Site does not allow mp4, so a…

@Backyarddog Paper cutting knife is indeed more than sharp enough for kitchen use. Please research more about correct use of steel. Steels are meant to straighten a folding edge. Yes, it will rip off a burr too, but you do not want it to do that, because you want to thin out the burr during the sh…

One of my favorite carving knives is from the 1800s I think, sure it tarnishes and rusts, but you can skip the iron in your vitamins. it is always razor sharp, sure it aint pretty, but been through henkel and other top brands and nothing compares. Friedr Herder abr.sohn solingen- germany
