Blade Honing Guide

For those who work with handheld cutting tools, it's no secret how important it is to have the right edge sharpening. Without special devices, it's difficult to achieve proper sharpening or honing manually, and you can easily damage the edge, leaving you disappointed with the tool's performance. There are many ready-made tools on the market that can handle this task. Below, I've listed examples that are quite effective, but I was curious to create my own device, which, in my opinion, would work just as well, if not better, than the presented options. However, it all depends on your skills.

All parts of the device are made from eABS+HS plastic by the well-known company eSUN. Many are familiar with this plastic, but for those encountering the HS designation for the first time, let me explain: it stands for "High Speed." With the advent of high-speed printers, working with regular ABS plastic has become inconvenient, as its layers don't fuse well at high speeds. Printing slowly is no longer appealing, so eSUN's new developments come to the rescue, allowing for products with excellent strength characteristics, minimal shrinkage, and the ability to print at speeds up to 300 mm/s and accelerations up to 20000 mm³/s.

For the roller, I used TPU plastic from the same company. Why do I recommend TPU? The honing process involves the roller contacting abrasives, and regular plastic or metal bearing surfaces will wear out. However, a TPU roller will last much longer. I used flanged bearings F693ZZ. All component links are provided below.

To adjust the clamping jaws, I used a threaded rod with left and right threads on either side, M5x70 mm, along with M5 nuts with left and right threads.

I recommend printing all parts at full infill with maximum quality and minimum layer height.
