Get it? "Honeboy", like "homeboy", only for honing chisels and plane irons? Yeah, I'm hip like that.

Compared to commercial products like:

Besides price, mine has a few great advantages:

• 100% rustproof
• more versatile(see below)
• rides more stable and smooth on TWO, wide-footprint helical-tread wheels

"Versatile"? Yes! You can sharpen items anywhere from about 1/2 inch to 2 1/2 inches wide or reverse the clamp for smaller objects (compare pic 4 and 5). If you need even larger objects, just make a longer sliding dovetail.

Also, since you're sharpening stuff, I found this sharpening stone holder on thingiverse you might also want:

This is also found on my projects blog, here: https://theheadlesssourceman.wordpress.com/2014/01/18/honeboy-sharpening-jig/

1. Print two wheels.
2. Print two snap-together axles, or use bolts. (The axles are "meh".)
3. Print two bodies. If you print fast/lores like I did, you may have to re-tap the holes to 1/4" 20tpi.
4. Print one dovetail. (Recommended 3+ shells.)
5. Get two 1/4" 20tpi thumb screws or 1/4" bolts and thing 177400.
6. Print, laminate, and attach a set-up sticker. (Not designed yet. Sorry.)

Note: The parts are designed to fit tight so you may have to file and fit.
