Thread: Is king 1200 deluxe working?

I'm trying to sharpen a razor: M. Jung, New York, made in Germany, #80. I am using a 1200 King Deluxe to set a bevel. I'm not sure it is cutting; I don't see any swarf, and is taking a while. I have also used the opposite side of the stone to sharpen knives. Some times it works better than others, so I thought I might not be caring for it properly. I also lapped it with 280 grit lapping powder to clean it up, but didn't help. Maybe I'm not soaking it enough or too much. Does anyone have experience with this stone, or any advice? Also does anyone have any experiece with this razor?

Thanks

I have that stone and lap it regular on a granite slab with a piece of 400 grit wet & dry paper with plenty of water thrown in for good measure, i usually soak the stone for about 15 minutes and really rate and love the feedback you get from King stones, never had any issues with them, soak your stone again and dont use the lapping powder, just try wet & dry paper laid flat on a perfectl flat slab be it granite or glass then see how it goes.

What makes you think it's not cutting? Looked under magnification ? Have you done many razors before on it.? Is it just this razor that's a problem ? How bad was the edge to start with ?
Are you putting a little torque onto the edge? I took out some microchips & set a bevel on a paring knife the other day on a King 800. Took about 2 minutes to raise a burr. I was in a rush & didn't soak the stone so there was no major swarf but the surface discoloured a little. I was surprised how quick it worked as there were no real indications till I looked up close.

The razor is dull. I did some work on a 200 grit Imanishi to start. I had to remove a couple of frowns in the edge. I can see some swarf on a knife I tried, but nothing on the razor. It doesn't feel like it is cutting on the razor; I have done about 200 passes on the King and it doesn't feel any different in sharpness. The razor is a full hollow, so I didn't want to put too much pressure, but am using some torque. I haven't sharpened a lot, just a 4/8 half hollow, but only used the Norton 4/8K on it. When I use the Norton 4K I can see some swarf coming off.

Thanks

If the razor has hard steel, 200 passes may be just getting warmed up after a 200 grit . I suggest looking at the bevel under magnification & assessing if the 200 scratches are being replaced or at least try a marker test & see where the stone contacts. They should be as I can't think of a reason why the stone would not cut but I am guessing you need to do more work.
I'm not suggesting pressure either just a little torque as you seem to be doing. Maybe try circles & back n forth strokes. If you have a diamond plate or some kind of slurry stone you could try raising a slurry.

Thanks for the help. I think I have made some progress, but I have done around 400 passes. I used the 200 grit hone with tape and then took the tape off for the 1200 King. I marked the bevel and did a few strokes. There is some left on the tip of the razor so it looks like I still need more work. Do I need to go back to the 200 or will I get there with the King stone? The razor has a slight smile and I am doing back and forth and x strokes. The razor has some uneven hone wear on the spine; more on one side. Will this affect the honing? If I hone with an x stroke I thought that would work.

Thanks

You are getting into some advanced work there for a guy who has honed only one razor before but good for you.

When you take the tape off you immediately lose contact with the edge & need to put in work on the 1200 to to re establish it.
If you have somewhat of a primary bevel set stick with the 1200.

If you have uneven hone wear there may be a warp. Can you check for that ? If so, depending on the severity you can either persist with trying to achieve the bevel by steel removal or you can "ride the horse in the direction it's going" ie adjust you strokes by rocking or rolling to make contact at all points on the edge. It is not a corrective technique but will give you a shaving edge.
