Thread: Pockmark in Chosera 1K

My new Chosera 1K just arrived and I noticed that's there's a small divot, like a pockmark on the face. Is that anything to worry about?

edit: photos

No, it's not a problem. I call it negative honing space. It will not scratch your edge, it will just not hone it. Here is a hone in which this was done deliberately.

Thanks! What would be the purpose for doing it deliberately? What benefit would this have?

It had as much benefit as a magnetic razor. It's just a marketing gimmick. However, the hone box shown in the photo claims that the holes help to prevent, or eliminate, wire edges.

How deep is it ? I'd probably just lap it and hone if it isn't too bad. OTOH ....... these do have a record of cracks developing with some users. Mine is years old and so far so good, but my Chosera 5k has some cracks developing at the edges. Harmless so far. Unless you're 'hot to trot' with it, I'd maybe ask for a pre-paid return label and a replacement. Brand new, and they ain't cheap, should be flawless AFAIC.

+1 on lapping it out.

Just received my Chosera 1k today. It came with the base, which I very quickly decided I absolutely hated. Turned the stone upside down, filled the base with boiling water, pouring and repeating until the corners of the base were heated enough to stick a metal spatula under the corner. Little wiggle here, little wiggle there, push to the other side, wiggle again... POP... wiggle some more... done. Base removed!

Then I took a handsaw and cut it to my preferred size, 140 x 70. I have a huge tomo now to speed it up.

Lapped it on 80 sic, then 120. Trust me, that can be lapped off. I lapped raw side of rock with 80 sic dead flat in under 2 minutes. I'm way too impatient and greedy and impulsive to return and wait on shipping.

It's a lot harder than I expected, that's for sure. I cut a Guanxgi and a King 1k before with a handsaw. The Guangxi took 45 minutes... the King 1k was so soft I swear I could've bit it off... the Chosera took over an hour... I had to go to home depot and use one of their more aggressive for-customer-use handsaws... finally came out.

Awesome stone though! You bought a winner!

That the white spot, upper left corner in the second picture? As long as you lap the stone, which I highly recommend for a new stone regardless of purchase, shouldn't be a problem. Especially because of the location, there is little to no contact with regular honing. Two of my naniwas have multiple pock marks in the middle of the stone and have no influence.

I always just pick the best side of my single-grit hones and use just that side.....Lazy!

What's the other side look like?

It seems to be glued into the base.

OH! You ponied-up and got the one with the base! Could be the best side is 'glued-down'.

We may never know!

Well, it's a one-shot now. We know which is the best side now.
Flattening-city!
