We have a massive amount of Edge Pro products so we figured it would be good to have a whole section on how to use the machine and what to use on it.

Jnats on the EP

Sun Dec 01, 2013 1:12 pm

Recently I had been asked why bother with JNats on the ep , you cannot work the slurry as it will all run off , blah blah. Well my short answer is that it takes more skill than freehanding , and that the secret is water control (the secret to a Jnat is water control anyways but it is especially important with EP use) , long story short I recently got a Maestro Wu folder in as a Christmas Present for someone else , and of course I had to tweak the edge a little bit. Well a lot actually....

So here we have the factory edge. Coarse , but it is a good coarse edge , nice and even , no residual burr , this is an excellent starting point.


So my first order of business was to do a minor reprofiled and take it from 20-22DPS and knock it down to 15DPS precisely. So I used a shapton 220 , then a 1k. Then I made the hop over to Jnats. First I used an Amakusa , then an Igarashi. No pictures of the edge at this stage sorry. Interesting note was that when I made the conversion to the Jnats I had a sizeable burr. I never bothered to remove it , and by the time I was done with the Amakusa it was gone. Jnats seem to have the tendancy to not form , or form very little burrs in my experience.

Next I moved onto an Aono Aoto , this is the first time in awhile where I have felt an edge and been pleasantly surprised. This would be a great all around edge. Nice and refined yet still "toothy".


Then I moved up to a Meara.


Then a Yaginoshima Asagi , she is really starting to perform now.


Then I went to an Ozuku Asagi , this is a great stone. I raised a bit of mud on this stone with a 1200 atoma (well broken in) , worked that for 20 minutes. Then I took it one step further , I doped the stone with some 0.125 CBN and took it beyond what the mud could do on its own , I worked the supercharged slurry for another 10 minutes and here is the result.


This was a fun experiment for me , and my findings reflect those already shown by Dr. Matt on youtube. He does some excellent videos and I would advise everyone to watch them.

Thanks to Bullman for selling me the knife , it is going to a good home.

Thanks to Ken for selling me the stones , and always being around to talk to and critique what I am up to. I have learned a lot from you and you are a true friend.

So anyone who says you cant use a Jnat properly on an EPA or EPP , I say phoeey on that.

Nice post & pictures!

I totally agree with you.

Thanks MR , I've thought about doing this for awhile now. I think next time I might try some 0.1 CBN.

Whether it is done on an EP or not, I love the pics showing the progression of the edge and how finer stones continually refine the edge, which to be honest looked really usable from the factory! Just from the super close-ups it looks like you took a decent edge and turned it into a very nice, very refined one. Just judging by the metal in the last pic, I bet that edge gleams! lol

My pocket knives don't have to be mirror polished, but I do like shiny edges. ;)

Great work! I would be interested in a more macro pic of the edge. Hell, the whole knife sounds interesting.

Alrighty , I will get on that there was some other people asking for macro pics as well :)
