We can measure the sharpness of razorblade without a fulcrum. But for knives, we have to use the fulcrum. Why?

I visited EOU youtube channel for check it but I can't hear it. 
Is it right? [bæs]

good evening besspeople

tonight i am looking for comments.....opinions.....thoughts on using them for belt sharpening......if you use and why and what grit.

i tried some back in 2013 .....i think 9micron & 20 Maybe.......all i seem to remember the razor edges cut my fingers a lot.

standing by

and......anyone tried the 3m 777F belts yet

I've read a couple of times that continuing to sharpen past a certain optimal point reduces the sharpness of a blade.  This isn't something I've experienced with plane-blades or chisels, and my knife-sharpening skills are poor enough that I wouldn't notice (unless I measured a lot more often than I do).  Anyhow, it doesn't make sense to me, so I'm hoping somebody can explain why that would happen.  I can understand it if the sharpening is with a soft substrate, such as leather stropping, then it would make sense (and dubbing a perfectly good edge is something I've done all too often).  But I don't understand how/why it would happen with stones, unless it's simply due to burr formation.  I'm not disputing the claim, I simply don't understand the how/why.  If anyone has an explanation I'd love to hear it, and if it's something other than burr-formation, I've very, very curious, indeed.

We do our best to keep the BESS Exchange free of spam and spammers, but occasionally a spammer manages to post spam on the Exchange.  Rest assured that we will remove the spam post and ban the spammer as soon as possible.

Best advice:  When you see a spam post about supplements, Russian beach towels, enlarge your whatever, or some other obvious crap not related to the Exchange, simply don't open the post. The spammers want you to read it, so just resist the urge and don't.

This is especially true if the spammer posts a web link.  DO NOT CLICK THE LINK!  Links posted by spammers can be phishing or a malicious browser attack subjecting your computer to a security breach. It is also good general advice that if you receive an email from an unknown or not trusted source that contains a web link, don't click the link and never give out personal information. Clicking links and providing personal information is the most common way people get into trouble.

Success with sharpening steels has been ZERO for me.

The  Mousetraps from Razor Edge has been around close to as long as I have:  https://www.razoredgesystems.com/

Also note their Mini Mousetrap.

What got me  thinking about "spring loaded steels" was this article sent to me by Mr. Max - take note at  8 minutes and 18 seconds:  http://www.youtube.com/watch?v=AwW89H1ol...e=youtu.be

Have you had experience with spring loaded steels?

Since woodturnerswonders.com had voided warranty for use of its CBN wheels with water, I've been looking for a substitute, and finally found a metalworking fluid that doesn't turn milky and remains transparent so that the edge and burr can be watched while grinding (I use CBN wheels with Tormek).

It is Metallium XDP2000
