Did something boneheaded the other day and accidentally damaged my Japanese Waterstone.

It'd been a while, and I'd forgotten that you're supposed to use this stone edge-trailing. I was polishing the blade into the wheel and the inevitable happened: as I lifted the blade off the stone, the edge caught the wheel and dug into it, creating a small gouge.

I am hoping (praying) that this can be repaired somehow, maybe with something like the TT-50 Truing Tool?

Any advice greatly appreciated.

Fabulous and super-helpful responses from all you folks who've replied.
What an awesome community!
Thank you.

If you're referring to the "Advanced Knife Sharpening" video... he does move the Support to the horizontal position without changing anything, but he states to "adjust the angle", (and doesn't actually hone anything).

(Not sure if this is the video you're referring to?)

Just thought I'd clarify this a bit... I think it's just a general demo of the position in this case.

Yes, actually that was exactly the part of the video I was referring to!
Thanks for pointing out he said to "adjust the angle". I missed that.
Would have been great if he demonstrated it too.
Does he mean set it to exactly the same angle as the edge angle?
I assume with the Sharpie method, or try the calculators other people have been referring to?

Seems I have been doing this wrong! Thanks for the pointers.

Greetings to the community. I recently purchased a T-8 and started my knife sharpening journey! I've read the handbook cover-to-cover, watched many instructional videos on the Tormek YouTube channel including the excellent Tormek Live Sharpening Classes on Knife Sharpening with Wolfgang and Sèbastian. I've sharpened about 20 knives so far.

On the practice of honing my knives on the leather wheel, I've come up with a few difficulties. As a beginner I want to hone with the knife in the jig using the Universal Support, at least until I'm more experienced to do it freehand. Wolfgang discusses honing with the Support in the advanced sharpening class, and recommends it for special knives to preserve the coatings or finish on the sides of blades.

So first issue is, with honing long knives using the support, the tip or handle hits the grinding wheel. So the stroke is interrupted. I tried removing the grinding wheel, but it seems the T-8 won't work like that - the honing wheel slips off the drive shaft - oops! Is there another position or jig orientation I can use to hone without the knife hitting the grinding wheel?

The second issue concerns the honing edge angle. Since the honing wheel diameter is smaller than the grinding wheel, doesn't that mean to hone at the same angle you must adjust the Universal Support? In his video Wolfgang does not make any adjustments - he just moves the Universal Support to the horizontal position then starts honing. This of course could be intentional, if the best practice for honing on the support is to use a slightly steeper edge angle. Just not sure.

What do people think?

I also read in the handbook (p.44) that occasionally, it is recommended to re-oil the honing wheel, in addition to recharging the honing compound. The handbook said one application of compound lasts for honing 5-10 tools. After that, it recommends you re-impregnate the honing wheel with a few drops of oil and apply fresh compound.
