Sharpening talk...
I decided to put one of the 950 Forum Knives on the EdgePro for a little enhanced sharpening. I set it so the top of the EP bracket is halfway between the yellow and green marks, which should be something like 12 degrees per side. I used a 120 stone to make the major cut and then smoothed it out a little with a 220 stone. I'm pleased with the results...it's very sharp.

Cut like silk?

I had three working blades that needed a little more than a stropping tonight. I luckily had recorded the Edge Pro settings for each and was able to quickly hone all three in less than 15 minutes right back to very sharp. 0 -

No, no... Cuts like stink. Your reading it right. No typo. An expression.0 -
I read the first page then skipped to the (current)last one.
I love my forum knife and have carried everyday since getting it.
I truly love it and think it is one of the best knives ever.
It really makes me want a 710 version of this knife!
We came so close to getting it before only with silver twill.
I hope Benchmade knife come through one day.0 -
hmm... I still use my old Diamond Lansky up to the ceramic stone, then strop. I get 1-2 months out of each sharpening with moderate use.
I do have the sapphire stone but I've found it to be fairly useless since it clogs up so quick.0 -
Gonna have to reprofile the edge on my new 940 ....... the sharpmaker doesnt touch the edge 
It,ll give me something to do tomorrow ...... the wife has to work X,mas0 -
DJ, that sounds like a fun task to keep you busy. I would enjoy doing that myself. The problem with us forum members having so many knives is that we never get any of them dull. 
My brother in Arizona has started buying himself a knife here and there and the other day he even ordered himself a Sharpmaker! He'll be hooked before we know it.0 -
My daughter in N.Y. got a mini Hardtail (PINK) for x,mas and shes already cut herself with it ......LOL
She calls and says "these things are sharp" LOL0 -

I have one kitchen knife in ceramic .......however I dont cook , but seems to be still good.
Just finished my 940 on the EP ......its a user now ......LOL
Hammer was correct on my scratches .......LOL
If your gonna sharpen a knife the value sharpens out with it so a scratch or two dont mean crap.
Its gonna make a fine user .....I went ahead and polished the edge so I dont have to use my compact to put on my make-up ......LOL
At first I tried not to scratch it , but once that first little mark gets in it ,,,,,,,screw it , I just let it go.
After all , I user is a user....... scratches dont slow the cuttin down at all ........LOL
Its was bound to get marked up sooner or later anyway ......It push cuts paper , so thats sharp enough for me.0 -
DJ....Time to rethink the wicked edge sharpener 0 -
Clamping systems dont work good on all knives Ive found.
Especially a blade style like the 530
But .........maybe your right ? Nah ......LOL0 -
I have a wicked edge and it rocks 0 -
Tonight I put a polished edge on a Kreined M2 805 PE. Then while the EdgePro was set up, I put a polished edge on an M4 806.
My sharpening log showed that the M4 806 was previously sharpened with the EdgePro top of bracket set at the top of the yellow mark. I just dialed that setting back in and it took no time at all. Without the recorded setting add 15 minutes. I'm just sayin...
BTW, some of these settings are the result of tweaking two or three previous settings to come up with what I think is perfect for that blade shape, thickness and pitch. We ought to pass along settings here on the forum to save guys tons of experimenting. I know I'd give em a try if I saw any posted here.0 -
Sharpening log....priceless 0 -
I just got three new sets of aftermarket stones for my Sharpmaker: 120, 150 & 240 grit. Can't wait to give em a try.
Source for the stones: Congress Tools, Inc. from Naugatuck, CT...thanks, DJ for the idea.0 -
Does anyone know what the grits of the standard sharp maker sticks are? From the diamond to the ultra? Thanks for you time. 0 -
Haven't seen the diamond, but there's a guy who's posted a chart on a couple of the other knife forums that shows the rest at about 600, 1200, and 3000 grit. Comparing sintered ceramics to standard abrasive grits is kid of tricky, but that's at least a starting point. 0 -
So I take it that the two stock sets of stones are the 600 and 1200...right? The 3000 must be that aftermarket stone that Spyderco sells as an ultra-fine or some similar name.quote:Originally posted by AxisFan:

Well, tonight I put an EdgePro edge on one of my Spyderco Southard Flippers. The setting I used was to put the top of the bracket at the top of the yellow mark. It seems to be the absolute maximum you would want to go. You might want to start with the top of the bracket half way between the yellow and blue marks.
I figured the CTS 20-4P steel could handle it. It seems to take an edge really well and it polishes up to a mirror. I made the initial cut with a 120 stone, then continued with a 220 and finally a 600. Anything finer than that would just be showing off.
I can tell that I need to flatten my stones before I sharpen another knife. They're starting to act like they're getting a bit dished out.0 -

I just checked my records; when I did my Southard, I went with an 18° per side edge (green mark, 36° inclusive) and... a 1K grit finish was as high as I took it. Showing off cuts great.
What method do you use to flatten your stones? I know my 320 and 500 grit ones are getting uneven enough to where it's starting to cause problems. I was just going to pick up a cheap diamond plate and use that.
On a side note, looking at my spreadsheet, I usually go 18° per side with most non-super steels - S30V, 154CM, D2, etc. Most of my M390 knives (710, 730, 707) are 16.5°-ish per side (halfway between red and green marks), and that seems to work really well for me. The only reason I did my Southard at 18° was that I didn't want to spend forever dropping it to 16.5° with that thick blade stock.0 -
The easiest way for me to flatten my stones: I get a bucket of play sand and park myself somewhere on a cement floor. Pour out about a 1/3 cup of sand and just start sliding the stone around in it. You can do a circular motion or back and forth. The larger rocks will move themselves out of the way and the stone will be gliding on the sand.
After a minute or two you might need to add more sand or sweep it back to the center. At that point, take a look at the stone. The dished out parts will be cleaner than the thick edges. Once the stone appears to be all one color, you're done.
Hint: I like to find a stain on the concrete and do this there. It will sometimes clean the stain off the concrete.0 -

No water, you just do it dry?0 -
Yes...just dry sand. 0 -

A knife just doesn't feel sharp to me unless it is < 20 degrees per side. I'm with Skimo, I'm usually happy with a 350-400 grit edge, which makes the job quick and easy, then a little cardboard stropping. That gives me an edge that will both shave and cut rope very aggressively.
I used to go to 600, but after reading your post I must agree that 400's would be fine for what I use now a days. Toothy edge is preferable to 600, 1000 level surgical cuts. I don't want to spend half day sharpening and needs to do it more often. (Unless mirror finish blade sharpening is a Zen experience for a guy).

Gettin lazy in my old age , been meaning to sharpen up an 800 M-390 for quite a while now ......
Just finished it up , didnt take as long as I thought or as much trouble as I thought.
Got the knife in a trade a while back and it needed to be sharpened bad .........so I finally done it.
I dont know why I posted this .....just bored today I suppose ......LOL
I dont go all out on the sharpening process as I used to , as long as it shaves hair is good enough for me.0 -

Very good point, DJ. I am hovering between 400 to 2000. With recent release in S110V and M390, I can go up to 2000 with Diamond sharpener. As you said, strop is a good approach, but I need to find better compound to use with those "harder" steels.0
