Alternate ways to sharpen hook knife and how to make it scary sharp
It is impossible to use this technique if the hook knife has a sharp curve since a sanding block corner cannot fit in between. In such cases the method we explained step by step will be much better for sharpening your hook knife.
Since you can design the Dremel bit to be thin it can reach into sharp turns of a hook knife. Also since it rotates itself, it will use the entirety of the sandpaper without making any waste. You also get ceramic stone bits that can be used for the purpose of sharpening as well. These stone bits are available in multiple grits, but they might not be available outside of a set, so you will have to purchase a whole set of bits for the Dremel if you want to sharpen your hook knife properly.
How to make your hook knife edge scary sharp?
For the inner edge, you should start off using 1/2 inch dowels that have sandpaper attached to them, and using rotating movement run it along the edge of the blade. If you aren’t sure whether you are sharpening the edge at all, then you can cover the edge with a marker. The area that you have to sharpen will be covered with a marker and when you sand it properly, the marker stains will have been removed. This will show that the whole edge is being sharpened equally and properly.
You can do that with every grit of sandpaper you are using on the hook knife to make it scary sharp. This will help indicate that it is time to move on to the next sandpaper grit as well. From coarse to super fine grit, up to 1000 or 1500 depending on how sharp you want your hook knife to be.
Removing the burr on the hook knife requires quite a lot of stropping since the hook knife is made of hardened steel. This is because brands want their hook knife to be durable without the fear of it bending too much under duress. Using the suede side of the leather and some polishing compound removes the burr with relative ease and some patience.
