<p>Remix of Parametric Kitchen Knife Sheath by bikecyclist and vorpal (Steve Pendergrast)</p> <p>Should work for any knife that is pointy at the end. (For non-pointy knives, guesstimate the length the blade would have if it had a point.)</p> <p>There is an option to provide the sheath with "windows" so you can easily tell if the knife is serrated and has the shape you are looking for without unsheathing it. These windows are on alternate sides of the sheath to facilitate cleaning.</p> <p>Update 1 June 2020:</p> <ul> <li>Now supports negative grip cutoff angles (Thanks to prb333 for the suggestion!)</li> <li>However, due to Thingiverse customizer shortcomings, the new version is not available via the online customizer. You'll have to download the file "Parametric_Kitchen_Knife_Sheath_V5.scad" and run it in OpenSCAD on your personal machine, I'm afraid.</li> <li><p>The new version is also available via customizer, here: <a href="https://www.thingiverse.com/thing:4418138">https://www.thingiverse.com/thing:4418138</a><br/> Update 23 May 2018:</p> </li> <li><p>Fixed a bug with windows in thick walls, as suggested by Laurie - thanks! :-)</p> </li> <li>Improved use of customizer interface</li> <li>Improved handling of sheath windows at large grip cut-off angles</li> </ul> <h3>Print instructions</h3><h3>Category: Kitchen &amp; Dining Summary</h3> <p>Remix of Parametric Kitchen Knife Sheath by bikecyclist and vorpal (Steve Pendergrast)</p> <p>Should work for any knife that is pointy at the end.

You can also specify the wall thickness of the sheath.</p> <p>The maximum width may be near the handle or may be near the tip depending on the style of blade, so measure carefully. You might want to add another 1 to 2 mm extra to the width and length, and 0.25 mm extra on the thickness. Maximum thickness is usually near the handle.</p> <p>2 mm works well as the blade thickness for typical medium sized kitchen knives. Calipers are helpful here. If you're using thin walls for the sheath, they are a bit flexible, and the optional ridges can help to ensure a snug fit.</p> <h3> Remix Information</h3> <p>An interesting remix that allows you to match the actual shape of the blade very closely (with a bit more effort in customizing) is the &gt;&gt;"Parametric" knife sheath (Sabatier profile)&lt;&lt; by davidhbrown:</p> <p><a href="https://www.thingiverse.com/thing:3834068">https://www.thingiverse.com/thing:3834068</a> by <a href="/davidhbrown/about">https://www.thingiverse.com/davidhbrown/about</a></p></p></p>
