I like the feel of these things but. My Packard extra heavy duty scrapers made with M2 high speed steel not easy to sharpen.
I have to ask what is best for this task?

CBN wheels to shape/refine the grind, then an Alan Lacer diamond hone to maintain it.

I have couple Henry Taylor HD scrapers and sharpen them on my bench grinder. Also have a burnisher but only use it when remember where left it last. Would not buy that burnisher at current price.

I sharpen my HSS tools on a Norton water stone (4000 grit). I also use DMT diamond plates for some of my HHS turning tools. Sharpening HSS is not difficult if you use a good quality stone or diamond plate. The cheaper stones and diamond plates have much less grit and will take considerably longer to sharpen any HSS tool.

CBN wheels are very expensive.

Yes, cbn wheels cost. But they are the best, and you’ll only buy it once.
I don’t know anyone who has worn one out yet. And wish I had bought mine before I spent good money
On alternative wheels.

I use CBN wheels and agree with others – they are SUPER!
I just ordered two Doug Thompson 10V (this metal is a couple of grades higher than the M2) gouges and I’m super anxious to get them.
I also suggest that you get the Oneway Wolverine Sharpening Jig. It take too much practice to sharpen by hand and get good results, this will help you avoid a LOT of mistakes.
With my setup I can quickly take a tool that has been incorrectly sharpen and turn it into a super cutting tool.

I sharpen my scrapers on a disk sander. It’s super easy to set it up for a 45° grind and puts an edge on really fast. If you already own one, give it a shot before you part with the big bucks.
