Rassenti Satori Sharpening on WE Questions

[shookj1]

Hey BF members,

I just picked up a new Peter Rassenti Satori (which is outstanding) but my one and only disappointment is, it isn't that sharp. No worries because I have a WE and have sharpened knives before, but I have some questions for those that can provide insight.


-It almost seems as if the two distinct portions of the blade have different angles for their bevels? Are you keeping them at two angles or are you unifying the edge. Is there a specific angle you are using?

- Provide anything else I may find helpful during this process please.

- The other side of me says I should just send it out to be "professionally" done...but I bought the WE to sharpen my knives and use them and maintain them myself... This is just a different caliber of knife than I am used to (ZT, Spyderco, BM, Hinderer...)

Thanks BF!

I would use the old sharpie trick. Draw some sharpie along the edge and take a few swipes with one of your fine stones. Adjust to match the existing angle the best you can (the stone should take all of the sharpie off, from apex to shoulder, when you have the correct angle). I would treat the 2 distinct sections that you have marked as separate edges. Find the angle for section 1, and go through your whole progression (200,600,800,etc.). Once you are finished with that, move on to section 2 and do the same thing. Just make sure that you do NOT roll over the point where the edges meet (line between section 1 and 2). You could even do different stroke directions to make sure that you don't do that. EX: Stroke towards handle for section 1, and stroke towards the tip for section 2. Hope this helps!

I have not sharpened that specific knife... but I can give you some general guidelines...

I would 1st mark both sections with a Sharpie, set it up in the W.E. then, using your finest stone (no strop), check the angle in each section, and see if they're the same or different.

Regardless of the answer, if there is a distinct difference between the two sections, then I would treat each section like a separate knife... similar to how a tanto is sharpened... making sure not to rotate the stone over where the two sections meet.

It looks from your picture that the front section does "smooth over" between the sections where a tanto is normally pointed... if that's the case, you could rotate the stone slightly. (I can't tell this for sure, but you get the idea).

For a first sharpening, I would match the angle (or angles) that is on there, mark it with a Sharpie, and use a fine stone to see that everything matches up. (IOW, don't go crazy). If the angles are close between the two sections... then you might just consider "unifying"... but that is up to you.... (and I don't know if it would affect the "value"...). Let the stone sort of "glide" over the edge, and follow the natural path (keeping the "treat each section separate" in mind).... IOW, don't use "scrubbing" or straight up and down strokes.

Holding the knife, I might see things a bit different, so maybe wait and see if anyone who has actually sharpened one has any additional points. But I think you'll find it easier than you're anticipating on the W.E.

You might also head to the W.E. forum, and ask there.

Thanks for the replies! Certainly some helpful information, so the blades on these seem to have an optical illusion to them making you think the bevels are different, but in turn the sharpie trick proved a 1-2 DPS difference, so I carefully matched the two edges through progression to 20 DPS. I now have a proper working edge that I can easily touch up. Thanks again!

I see you already solved this thanks to the helpful answers above... But for others that may read this later, I suggest using a sharpie as well, and keep them 2 distinct edges (don't blend them). I've only sharpened one of these before but it wasn't too difficult. Just take it slow and don't stay in one spot on the recurved section.

Thanks for the comment REK! Very informative from somebody who has WAY more knowledge than me. Whoops on my part for blending the two edges, but I did make sure each part of the blade was sharpened as its own, I believe this will serve my purposes well and make it easier to touch up later.

But WOW what a beautiful edge on that one you did!

Op I was wondering how you did the recurved edge (1) with the WE system. I have the KME and I had to buy a 3 sided curved Diamond stone attachment for more $ but it worked out well.

You can just use the normal stones as long as the recurve isn't too extreme. You would just be using the corners of the stone when in the recurve section. Just make sure you keep the stone moving along the edge so you don't cause any weird deformities in the recurved portion.
