Serrated knife sharpening wheel

[Garrett47]

I saw an announcement earlier today about new Tormek wheels for sharpening serrated knives. Where can I get more info? I looked at the website and did a search but couldn't find anything. Any guidance appreciated.

Wow, a triangular wheel ? With a dual-MB102 "spaceship" contraption for truing it ? Or with a diamond-coated apex ?

Garrett,

I saw what I believe is the same wheel for sharpening serrated wheels on facebook. It is actually a Slipakniven product, not Tormek. I don't know anything about it, although I have had success with the few peoducts I have ordered from ẞlipakniven.com.

So this is actually a thing, even though not a Tormek thing...

Still, there are two fundamental issues with such wheels :
- If the wheel is noticeably wider than the serrations of the knife (as seems to be the case in the pictures on their website), then the result will be rounded out teeth and untouched "valleys". If the wheel is noticeably narrower than the serrations, it will be fragile *and* will cut aggressively.
- How do you restore them when they wear down ? I guess one could use diamond plates and aim for a triangular shape, but it will be fidgety.

IMO, a thin triangular or cylindrical rod used either freehand or on an edgepro-like system will make for a much more controlled process and repeatable results. Along with a flat benchstone for the backside.
