Easy Chef Knife Handle Oiler

thingiverse

I love nice chef knives! I am also busy and often quite lazy, especially with menial maintenance tasks! So, oiling handles often gets pushed waaaaay down the list of things to do!To solve that, I made a simple knife handle oiler. It separates in two halves for you to add and change sponges and oil easily, and holds together with a satisfying clunk via little magnets and two positioning clip hook things.The inside is cellulose sponge, but there any may be better media more easily available for you that will hold oil without falling apart. I hot glued the first layer and then wedged in a second layer on top.Here's how you construct it: print each side in PETG, with supports, as shown in the screenshot. When printed, superglue in 32 x 5mmx1mm neodymium magnets. I bought mine off Amazon for less than a cup of coffee. Make sure you check the orientation of the magnet with the opposing side before gluing it in (don't ask me how I learned this lesson!). The easiest way to do that is to take a pair of stuck together magnets and mark the back of each with a marker, so you know which side to glue down. Then, glue the marker side down in the opposite pair position on each side. Finally, hot glue in some sponge, pour on some knife oil, and you're away.How to use it: hold the knife by the back of the blade and slide the handle in the hole. For knives that need just a thin layer of oil, slide it in, pull it out and then wipe it. For knives that drink oil, leave it in for half an hour and go have a cup of coffee. When done, it should sit in your cupboard without leaking oil everywhere, assuming you weren't too aggressive with the amount of oil you added. It's now there whenever you need it. Enjoy!
