IMHO, The Sharpmaker should have been named the SharpKEEPER, as I've found it more useful to touch up blades rather than reprofile or hog off a lot of stock...
In my piglet-like sharpening endeavors, I've found the Sharpmaker VERY useful for touching up the apex and applying a microbevel on large fixed blades, YMMV.
Coarse wet/dry sandpaper + a strop block would serve you better for high volume stock removal, if you want to go full hand finishing only...
Belt sanding, slack & platen both, if you want the fastest (but riskiest in terms of HT damage) method...
Sending to the shop (when it reopens for new business) is the safest route....Good Luck with your endeavors and keep us updated!
Oh, BTW, have you ever used the TriAngle rods freehand, like files?...I like employing them that way better than the recommended way sometimes! :thumbup:
