Thread: Bad honing or bad steel??

I was using X strokes as the toe doesn't really get honed without it (I've marked the edge with sharpie a lot trying to perfect my technique in the past). I had read in a post that one guy didn't leave his 1200 grit stone until it passed the HHT, so I did increments of 5 laps trying to fine tune it to pop hairs. After about 5 or so increments I just moved on to the 4k/8k as the razor never passed the HHT and I was afriad of over honing...maybe it was already over honed after those increments?

That guy could very well be me...
I'm not a big fan of the sandpaper. It has a tendency making a little wave in front of the razor. If this happens, even a nearly invisible bit, your edge will never become sharp.
Unless you need to hone out a chip, or corrosion, or some other mishap, I would not use that sandpaper. (Even then, I'd use a coarser hone, instead of sandpaper)

Your Norton 4K is perfectly capable of setting a proper bevel on your razor, and you should stay on it till you can pop a hair. Don't worry about overhoning. (It doesn't ruin your razor, should it happen) Stay on that 4K till the razor cuts arm hair effortlessly. Even if you don't make it to the HHT, this should be easily doable. When the armhair test is good, continue on the 4K with very light strokes, just a dozen laps more. Try the HHT again. Do another dozen light laps if it fails.
If it doesn't pass after that, don't worry too much about it, and start doing doing your pyramids.
After one cycle, test for the HHT again. If it passes, do your 50 on the Chinese 12K.
Don't use the CrO, but go straight to the leather for 100 laps.

This should give you a fine shaveready edge.

IMHO, the HHT is a fine test, if you know how to read it. At the bevel setting stage, it can tell you that you're good to proceed to the finer grits. You may need to fumble a bit, by dragging the hair accross the edge, before it catches and pops. At this stage, that's quite acceptable.
After stropping a completely honed razor, with some experience, the way the HHT performs can tell you something about the keenness of the edge. A not superkeen edge behaves as I decribed above. A better edge, pops the hair with a sound, as soon as it touches the edge. A premium edge fells the hair silently, seemingly before it touches the edge.

Good luck,

Bart.

That last post sounds promising...it seems like I can always get the razor to shave arm hairs effortlessly. Most of time I can run the razor through my arm hair it will pop off a few free hanging hairs. So maybe I just need some more time on the 4k. Then onto the pyramid and 12k. I'll give it a try when I get home!

Thanks for the help guys

The 1000 grit sandpaper is what I use also but only to remove nicks and old, oxidised steel, not to set a bevel. I have to be careful that the sandpaper does not bunch up in front of the edge as I am honing or else it will "round" the edge. I am also looking for an alternative to the sandpaper and will be trying a Scottish Dalmore Blue stone and a natural Japanese stone in the near future as options. I do not like the Norton 1000 because it is so slow and the DMT diamond hones are to harsh on the steel.

For bevel setting I use the Norton 4000. It has always worked for me.
For testing the 4k edge you can use the TPT, arm hair test and maybe the HHT. I never used the HHT in the past for the 4K. I saved the HHT for the Norton 8000 edge. That always worked for me.

One of the major errors I have seen new guys do is to hone to fast.
Slow down your stroke to about 1 second per side of the edge. Watch the water flow in front of the edge. That will tell you where your pressure on the edge is. It should take about 60-90 minutes to hone a razor from scratch.

Well, tried to hone the razor again last night but I still couldn't get it to pass the HHT.

Started out on the 4k in increments of 10 laps trying the HHT between each, after about 8 of those it still didn't pass (cut arm hair just fine though), so I just moved on to a conservative pyramid and stopping. Still couldn't pass the HHT after the stropping.

The shave wasn't terrible...but not great either. It was better than past shaves, which is promising. I guess I'll try staying on the 8k to see if that will help. Maybe the edge isn't was sharp as it should be coming onto the 4k from the 1k sandpaper...I'll be saving for 1k stone!

If you are where you say you're at it is just a touch more to go....
Stay on your highest grit stone, do 2 sets of 10 laps and go as light a touch as possible on the second ten.... that 12k chinese might take 3 sets of ten...
After the stones do 20 perfect laps on the Cr strop, then 50 linen and 100 leather and see if that doesn't bring it into line.....

I agree with Glen, your almost there. Easy does it from now on.

I've got a chinese 12k, should I use that for the last 2 sets of 10 laps? I've read they are very slow cutters, will 20 laps be enough?

I've also got a small coticule that was thrown in with another ebay razor, but I don't have a slurry stone for it. This might be a ridiculous question, but I was thinking that since the chinese 12k and the coticule are about the same grit could they be used on each other to form a slurry on the coticule? I'd like to try it out as a polishing stone.
