Para 2 - reprofiling question

Hi guys. I have Para 2 and I would like to reprofile it in order to get a microbevel on it. I did the sharpie trick and I found out that at the beginning of the blade there is 11° and it goes to 15° as we go to the tip (the secondary bevel is about 18°). If I set my Edge pro to 11° at the beginning of the blade I would have 11,8 at the tip. Are not these angles too acute or is it still OK? IF ok what microbevel angle would you recommend,15°? I do not have almost any experience with S30V.
Thanks

I just did a pm2 at 18 deg. was a bitch to clean up. Also with an edgepro. To get to 15deg would take forever. The trick is the atoma diamond 140.Start the 140 until full apex say 15 deg, then the next stone 15.10 deg, and so on. There is no worry about apex the next stone. So for reference i start 15 deg, the next stone 15.1, next 15.2 etc...
The magic is the full apex the first stone.
 
I run at about 24 deg incl main bevel, and 30 deg incl micro bevel on most of my folders. The increase in cutting performance over stock is very noticeable.
 
I personally would not take S30V that low on the Para 2. Just me though from my past experiences and usage. I would only take a "tougher" steel that low.
 
What I've noticed is that most Spydercos are thicker towards the rear of the blade and much thinner towards the front. If you set your Wicked Edge to 11 deg, you will most likely get an 11 deg profile all the way across but the "Profile" will be taller (much taller) towards the front of the blade. It may make your bevel look uneven... But i guess there's only one way to find out... Post a pic when you are done!

An edge that acute would be more delicate than you're average factory edge but it's all relative... What is it's intended purpose, if you are opening boxes and letters, cutting twine and lighter duty you should have no problems with a profile that thin. IF you are breaking down cardboard or drywall, that may be a bit too much to ask of an edge that acute.
 
I just use a standard 15 Degrees per side for S30V, works fine.
 
I reprofiled my PM2 on the EdgePro at 15 deg per side and I also would not go that low on S30v. It has chipped a couple of times also I have to touch it up a lot.

 
I will use the knife for everything. Opening boxes, cutting cardboard, cooking.. But not heavy stuff like battoning. These two pics look awesome. If I wanted to fix the bevel and create nice microbevel, it looks that I have no choice but sharpen the blade at 11°. When it is sharpened 12° and more Im almost hitting the secondary bevel. Angle cube says 12,5° in attached picture. If I were sharpening it at 15° I would have nice tip but rear of the blade would be bad. What would you do? :-)

I have some knives that are sharp, but not clean all the way down the bevel.I figure a few sharpenings and they will clean up. I would set the edgepro at 17 deg and work on it and see what you get. Post a photo and get some more feedback.
 
Why 17°? Isnt it too much? Should not I rather sharpen it , lets say at 14° and just do more work on the rear of the blade? :confused:
 
3 hours of sharpening on the 220 stone at 14deg and still not there. It takes like forever

Looking good. It does take a long time to reprofile, thats why the diamond stones, plates are so popular.
 
Yep, Im seriosly thinking about getting one. I was reprofiling AUS-8 steel from 15deg to 12deg and it was litterally couple of strokes on 400grit stone :-)
 
So it took me 5hours on the 220grit stone to reprofile the bevel - hardcore. Maybe in time I will polish the bevel but for now my hands want to rest :D I decided for 17° microbevel.

Nice work... Wow, that's a long time for a reprofile on the Edge Pro...

I also use the EP, and I find the standard coarse stone (120 Silicon Carbide) works **much** faster than the 220. If I remember correctly the 220 is Aluminium Oxide?

I have reprofiled S90V Military, South Fork, 20CP PM2 etc and it took maybe an hour at most to reset the factory edge to +- 25 deg incl with the 120.

For that reason I almost never use the 220 to reprofile.

You should really look at getting the Atoma 140 grit diamond plate. It's expensive but your reprofiling jobs will go MUCH much faster.
 
Ill look into it but hopefully I will not have to reprofile anything soon. I used to have cheaper knifes made of 8CR13MOV, AUS-8 and so on. This is my first knife made of very tough steel. I created 17° microbevel and it is sharp but does not shave hair as easily my Tenacious with 20° microbevel. Both are sharpened on the same ceramic rod - 900grid... Do I have a problem somewhere or S30V is just harder to get hair shaving? I heard some steels are...

edit... my problem :)
