Sharpy

<h3><i><strong>Sharp edges can cause severe wounds‼ &nbsp;use your brain!</strong></i></h3><h4>&nbsp;</h4><h4>KeepSharp</h4><p>This is not a sharpener for dull blades! This is to keep a sharp blade sharp by conditioning the very edge and correct minor deformations from usage. Most sharpening tools work on both sides without keeping a proper angle. When moving the knife parallel to the guide (riffle), the sandpaper will touch the tip at an exact angle of 20°. ( for other angles use the script to make your own).&nbsp;</p><figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/88361/rich_content/67e700f7-76ac-4445-9b9c-db7b2e304910/grindingangles.gif#%7B%22uuid%22%3A%227d0ea0fc-91bb-417f-976f-304809cea305%22%2C%22w%22%3A459%2C%22h%22%3A196%7D"></figure><h4>post printing</h4><p>Put a piece (25×25mm) fine wet Sandpaper &nbsp;(grid 400 - 600 CAMI / &nbsp;P800 - P1000) into the slit and bend over (you could also use adhesive).</p><h4>Use</h4><p>With a wet knife in the wedge by moving the knife back and forth without force. For better usability glue the sharpy onto a vertical surface. You can use it on both sides but this is not necessarily &nbsp;— if you are using this on sheet metal, a axe or a scythe, please use the guarded version for little more safety not slipping with your fingers into the blade.</p><ul><li>To confirm functionality use a marker and color a small area of the cutting edge. When using the sharpy you should see the color removed at the edge.&nbsp;<ul><li>&nbsp;if only a fine line at the very edge is removed ↦ you could use a lower angle version</li><li>if a line at the very edge stays colored ↦ you must use a steeper angled version</li></ul></li></ul><p>&nbsp;</p>
