Knife Sharpening DIY MDF Wheel #shorts

Click here for the detailed video:

Build a knife yourself, was on my to-do list for a long time. Now it was finally time, the last "push" was that again "7 vs. Wild" in Youtube Germany comes. The format has already captivated me last year, so I decided to make a survival knife with Stonewash. For this project I had to cut knife steel, work with the belt grinder, drill, saw, file, harden with the hardening furnace, work on the lathe, sharpen the edge and much more.

This video is not only to quickly show someone how something works, but also to relax and get away from it all! Relax while watching the video and enjoy what you see and hear. I recommend you put on headphones and listen carefully at certain points (I've highlighted them), as there are often very strange sounds there.... Enjoy!

▶ What did I do ?! ◀

With the angle grinder, I roughly cut out the shape from a knife steel (1.4112 - 440 B/stainless). With the belt grinder I then ground it exactly to the desired contour. After drilling the holes for the pins, I used a file to file the thumb ramp onto the back of the knife. Using a belt sander, I ground the cutting edges to the blade, but first left 0.5mm so that the blade would not curl during hardening. After hardening in the hardening oven at 1040°C, I tempered the blade three times at 200°C and 60 minutes in the oven. The blade now has a hardness of 58 HRC. I glued black G10 liners to the walnut handle, cut out the outline on the bandsaw, and gave the handle its final shape with the file. Now all I had to do was taper the edge, turn the brass pins on the lathe, and glue the two handle halves to the blade. After filing down the pins and fitting them into the handle, I sharpened the edge with an MDF washer and polishing compound. Finally, I treated the walnut handle with linseed oil varnish.

Not bad, a bit fast though, be careful not to lose your temper ... we had a low speed oil bath grinder when I did meat cutting, but I think I would still prefer my stones, ceramic, steel, and leather.

I've got the razor sharp wheels, work great for about 5 knives, then need regritting.
Trying different glues, anyone having grit retention problems/ fixes? Razor sharp says should be able to do 100

You have the wheel spinning in the wrong direction. You should be grinding on the top of the wheel for stability and safety.
