I finally got my K390 Endura dull enough to require sharpening. Freeing up the root balls of some spruce trees I was planting, I had to cut away a lot of wet burlap that was saturated with soil and sand. I didn't notice that it was also stitched together with heavy steel staples. I probably hit those staples several times while cutting through the burlap. Anyway the knife was seriously dull after that. To bring it back to paper towel slicing sharpness took 100 passes on the diamond rods of the Sharpmaker and then another 150 or so on the brown rods. I've been really enjoying the performance of this steel, but was concerned how difficult it would be to sharpen. Turns out it's not bad at all. Liking it even more now!

Very nice.

Been using K390 Endela for about two weeks now. Not a lot of experience so far but it’s scary sharp and seems to keep edge really well.

I’m thinking this is from the plunge grind but I’m not sure, probably need to thin this out....yes? any ideas?

Right, I put the choil in. I’m wondering why it’s devolving a recurve...possibly just need to thin out the plunge grind. So it’s symmetrical

Dav(id)03 Dav(id)03 you are clearly the type of guy who is confident enough to do some minor mods. I'd say get after sharpening that up to your standards. I've seen that on a GB2 and a good, full profiling on a system like a wicked edge, or even working it in on a diamond plate\stone will straighten it out.

There are two schools of thought here...

1. "That isn't right! Send it baaaaacckkk!"
2. Fix it and move on.

Hi Dav(id),

You can't send it back. You modified it. What would you expect whomever you send it back to do? Throw it away? Sell it to another customer after you modified it? Sorry Dav(id), you own it. You fix it.

Never mentioned or hinted in selling it or “sending in back”. Just lookin for some insight as to why after I sharpened it, the angle was greater near the heel, causing it to look like it was developing a recurve. 100% my lack of foresight and understanding of the grind.
But thanks for the reply sal...have a good weekend.
