Do you have an old 35mm SLR camera in a cupboard somewhere?

If so, the lens, removed and used back to front makes a really high quality magnifying glass.

Just once, so you can _see_ what's happening, go through the sharpening process you use, and look at the edge with your lens as you go.

That's a good tip. Wehn you're trying to learn about sharpening, a lens can be a trustworthy source knowledge.

If you don't have an old slr lensone you can get a loop for a few quid. Try the watch repair places like cousinsUk

I think I'll go for a rounded bevel, held in a jig with an oil stone resting on some scary sharp and with some waterstones standing by in the background. (hammer) :deer :mrgreen: :shock: :eek:ccasion5:

And when the cops come around to take pictures you need some blingy shiny LN type of tools sitting randomly in the background......:)

I hate to say it and hope it doesn't tip you over the edge, but rounded bevels are the norm with knife and sword enthusiasts. Not one but TWO :shock: making what they call an "appleseed" or "lenticular" bevel. Shocking!
Google it if you don't believe me.

So if you must kill yourself a couple of rounded bevels will make it easier!

Hope that helps.

To be fair, Jacob, you are quite correct in your assertion regarding bevel contours and Japanese blades. But, you fail to mention that these bevels are maintained with waterstones, preferably natural, with no hint of oil :)

Adam
Er. so what difference would that make? Non at all except the rust and the mess as far as I can see.

Here's something you won't see on UK TV. A craftsman demonstrating his skill on a chat show.

Lots of good stuff on display, including sharpening. The bevel is flat, No dipping or rounding. He uses the "balance the tool on the large single bevel" technique, so the bevel controls the position of the tool, not the other way round. There's a quite spectacular demonstration of how flat the bevel is...

This is at 4:20 into the video, for the impatient, but the whole thing is an interesting watch.

Er, where is it?

The other way round presumably being the craftsman controlling the position of the tool? Makes much more sense to me - sharpening and actual woodwork alike.
 
私は、花崗岩のスラブを中心に怖いシャープを使用し、幻想的なシャープネスを得る。約2000グリットに下る。私は通常ベリタスジグでブレードとノミを保持するが、時にはフリーハンドに行く。あまりにときどき油石を使用しますが、マジシャンが、彼らはあまりにも乱雑であり、私は鋼の近くに水をほしいと思わないウォーターストーンズ好きではありません。
 
Great vid BB,

Really interesting to see the contrast of a genuine Japanese craftsman using a water stone vs what I get up to. Free hand flat bevel, I love you.

Use the scary sharp around the slab of granite, I get the sharpness fantastic. I go down to about 2000 grit. I hold the blade and chisel in the normal Beritasujigu, but I go to the free hand sometimes. You can use the oil stone from time to time too, but the magician, is a messy too they, I do not have the water like stones do not think you want the water near the steel.

Don't worry it really isn't complicated, you just have to make the two sides of the chisel form as thin a point as you can. Anything that removes metal will do this (diamond,oilstone,waterstone,ceramic,the kerb outside your house etc.). As you can tell there are some firmly held beliefs about the best techniques, but bear in mind that all of these people (I'm pretty sure) have sharp chisels, therefore all these techniques will get you there.

Personally if you are just starting sharpening I would advise you go with flat back/flat bevel to begin with. This is purely for simplicity, keep the back flat on the stone, keep the bevel flat on the stone as you work it and you will get the chisel as sharp you like. Later to save time and effort you can bring in other techniques.

Just to show off a bit I popped down to the shed and with a bit of stropping I got my carving chisel to do this:

It's hard to get the detail to come out on the photos, but I managed to split the hair lengthways. This took about 5 mins touching up from how I had left the chisel a couple of weeks ago. A truly expert sharpener could get a finer edge than this, but for carving it is enough.

Hope this helps.

Fascinating. I guess Beritasujigu is Veritas jig. That's not very Japanese is it! He's right about water and steel though - you get rust.

:) I've used waterstones for thirty years, and not once have I had a problem with rust. :)

You've clearly been clued in to the ancient Japanese sharpening lore of "drying off your tools after getting them wet"...!
