I saw this from Joe Calton the other day, brilliant pencil analogy and demonstration:

I tried the above method and got good results. I used a paring knife, and the Norton Economy stone. A narrower stone would help to see what's happening. I also hang the end of the stone off the edge of a table so the angle stays more consistent.

I used to sharpen in a similar manner, it definitely works. I like the EZE-Lap files also, very handy.

I have been thinking about trying this method too for my dad, who is hesitant to just jump in with sharpening, even though I've given him several run downs of the basics.

Using the edge of the table is a great Idea, I was thinking about a few wedges cut at different angles, then you could use different cutting boards etc and slide the knife up to the file, and whammy, you have your angle. The table edge is more elegant though, no extra equipment required, and you can match any angle by sliding the knife closer to or further from the edge.

Not sure if this is good or bad. The poster gets practical results, but the working edge produced by stropping on Brasso loaded (charged) denim seems to be nothing more than burr realignment. The initial burr being produced from edge trailing sharpening on coarse wet/dry paper. The assumed low quality stainless steel blade (SAK clone) does not facilitate the production of an unbiased apex.

I like the even and clean edge - this 6k natural stone takes the tormek to another level

Pavol has some great videos! Even though the are in Russian, I can still watch because he has captions on his videos in English.
I wouldn't mind a system like that, but I would probably get the Jet brand version just because of cost.

Oh! I wonder which on I was watching in Russian. Is the guy who does all the destruction tests videos in Russian? That one has has English subtitles also, I think they are auto-generated.

Car window sharpening.

I guess this would be along the lines of using a coffee mug?

Yes, it tends to be mainly burnishing. They actually do make glass burnishing rods specifically for this purpose, well regarded by kitchen knife users in general.

This is has to be what keeps Cliff up at night sometimes. I don't know about buying the strops, they should sell those haircuts.

4Skore? tongue sticking out smiley

Seems like a sponsored positive review ...

wakko aka virtuovice, our leader , really upped our level of sharpening knives, naniwa stones ... bark river ...

that seems to explain the ~100 pps stropping

But they call this cheap beginners kit ...

start $80 naniwa choosera 1000 grit waterstone,
then finish with genuine pakistan $66 strop
loaded with $15 of coarse/fine compound ...
...
same store same brand but $9 cheaper , two waterstones ( 240/800, 2k/5k ) with a rod (1200 )

"Modified Murray Carter Waterstone Sharpening"

Not to sure where Murray Carter's influence is here, but that's the name of the video:

He seems to have changed the title, there is no reference to Carter now. It ignores the main argument Carter uses to criticize almost all other sharpening methods as well which is absolutely critical to Carter's style - you have to grind the blade bevel, not just the edge bevel.
Re: Things that are actually ok - sharpening videos

Cliff,
Sorry, you are correct. He states in the video that his technique is a modified Murray Carter technique, which I mistakenly paraphrased as the title of the video, which actually is "Water Stone Sharpening". I just didn't really see that much in common with Carter's technique except the King stones and trailing passes, although the maker of the video seems to use them exclusively.

I thought this was pretty great compared to the vast majority of YouTube videos I've seen that are about sharpening axes and even most knife sharpening videos:





The only thing I don't quite get is the circular pattern of stone movement.

Ryan,
It's to massage and align the carbides so it cuts better.....

But seriously, I think it comes from an efficientcy of movement with small stones, as a lot of ax hones were puck shaped.

Well I just meant in relation to the scratch patterns, the circular motion is something I haven't seen under magnification. I don't know what it looks like or how it would affect things like burr formation.

Most people find it way easier to follow the curvature on an axe with that motion. Axe bits often have much larger curvatures than knives. If you try to match them with knife type passes then most people have a lot of difficulty.

Generally, and this is what most people now don't realize, the circular motions were just shaping, the actual final edge bevel was put on flat (v-grind) just like with a knife and then (when people were very particular), the axe is stropped to intentionally polish and round the edge. Axes don't do any draw cutting, you don't need slicing aggression and they are slamming into wood on the end of a 3' handle, strength/toughness tend to be more important.

But, most people don't do the last step because in the real world wood is dirty and so are you and so is everything else. It isn't like you can keep the axe head sterile so dirt does wear the apex down, flatten and chip it, which is why most people will sharpen axes very frequently. Plus try chopping with an axe continuously for more than 2 hours and see if you don't want an excuse for a break anyway.
Re: Things that are actually ok - sharpening videos

Cliff,
Thank you. I suspected that the circular motion was shaping, and since you rarely see people do the last two stages you mentioned, I wasn't confident to say one way or another. Plus I don't have anywhere near the experience with an ax as I do with a knife.
