Thread: Unknown German water Hone

I just recieved this hone today and would like to have some help to id it. The next question is: how do I remove it from the box, it's probably glued to the bottom. The size 187 x 40.

For color comparison: On the left a light green Thuri from Hatzicho, the next is a grey green Escher, then the ?new hone and on the far right a Swedenstein.
The slurry is from a 600 Atoma
It has a blue like hue to it.
It slurries easier than the Escher
There is some blue in the Escher that has the same color as the new hone. My best guess is a light blue Thuri.







Any help would be appreciated

I think they used hide glue in these cases. I removed mine very easily - just put some boiling water in a flat pan and added the stone. About 5 minutes later the stone was out. Keep the water level as low as possible so as not to undo the glue in the box too. If you do, it's easy to glue back together, so no worries.

Isn't it a bit risky to put a natural hone into boiling water ?

I've heard about heat related fracturing risks

I think that's more with J-nats? As I tried to say, best to keep the level low. You could lower the temp if you like, or if you're really worried get the hairdryer and just heat the bottom. It should wiggle out after a while. I'm a 'throw caution to the wind' kinda guy.

Thanks,
I think I wil take the lid of the box first. And I will try the hairdryer trick first. If I would put it in hot water do I do that in up side down position?

the glue is at the bottom of the stone, maybe a bit on the sides. So you need to heat the bottom only. If all else fails and you have had no luck, then just pour lots of water. The box will probably come undone, but easy to glue back together. The whole process will only take a couple of minutes, so not long enough to damage the woodwork too much.
Not sure if you really need to take it out of the box, by the way. It's still equally difficult to use. haha. Just remember, it's a finishing hone. so between 10 and 30 strokes is all you'll ever really need. No grinding away on these.

The Escher is about the same size and has been my favorite finisher lately. But maybe I just need to take the lid of to comfortably balance the stone in my hand while honing. The hairdryer loosened the glue of the box at the hinges so maybe I will give it a try later.

Boiled quite a few of them to remove gunk and oil without any problems at all.

I put some of mine in the oven at low temperature and it loosened the glue enough for me to get the stones out. I think I've only resorted to hot water once for a Fox 44 hone but I did it by putting the room temperature hone and box in the water and then heating the water very slowly to avoid heat shock.

Thanks Utopian for the low temperature oven trick, I think I'm going to give it a try tomorrow.
