Lesson 1 XXcourse stone stock removal
We will be working with the following items
XXcourse stone,water, your knife and a Rag. The stone, knife and water will be oriented in this manner:
You will have mapped out in your head and on the knife with magic marker a rough outline of the metal you want to remove.
Here are some fast and dirty diagrams to help you. Remember on most Busse Knives the tip is thicker so you can either try to grind some taper into the blade with a stone by hand or have a wider edge bevel. It is possible to add some taper with a stone it just takes hours/days. Let me try to draw you a picture
First picture is of the blade from the side. The blue area is what a bevel on an average Busse knife will end up looking like if you go for a constant bevel angle. Note it gets wider out by the tip. This is because the blade is thicker there.
The second picture is the view you would get if you snapped the blade in half and looked at the cross section. Once again the blue part is what you want to remove.
Here are some pictures of before and after in a FFFBM that has had some taper added in addition to convexing.
Before
After
Next we take our blade and draw out our new bevel. On the knife I chose to work on the maker did add some taper to the end of the blade so the edge bevel will stay the same width more or less. Here is the before marking picture and the after marking shot.
OK now lets wet our xxcourse diamond stone and cut away the excess stock. Here are some pointers. Youre going to want to stop before youre done. Everybody does. Youre going to panic because it looks bad. RELAX it is going to look like hell until we get to the sandpaper part. Go ahead and make that edge bevel thin. If you go to thin we can easily make it better again with the sandpaper convexing. You want to keep going on one side until there is a good burr the ENTIRE length of the cutting edge. Keep the stone wet and clean.
I am going to do mine real quick so you can see whatit is supposed to look like. I will be back with more picture shortly.
