I am just starting to make knife's by stock removal and have some question's. I've finished my first 2 blades and have 3 ready to be heat treated.

I left a fair amount of meat where the cutting edge would be. One reason for this is i hollow grind and have blown thru the center of my hollow for going to thin.

I'm trying to figure out the best way to sharpen these and so far have ran into alot of issues. Steel is O-1 and heat treated for 58 rockwell. I thought i'd try my sharpmaker (fat chance would take a year to sharpen).

Then i went to a large corse sharpening stone. It took about 3-400 strokes, had a nice plie of stone dust, and still didn't take it down enuff.

I always wanted to try some diamond stones for my sharpmaker so ordered those (still won't do crap)


I know i should just use my 2x72 belt sander but how can you get consistant angles. I tried today and had some good result's but am wondering do most guy's use a jig of some sort? Do you guy's just get a feel for the angles and freehand it?

I am also wondering if you use the belt to get you close then use some other sharpening system to finish the job. Right now i used mybelt to get me close then used the diamond sharpmaker stone's. This is still a really slow process.

If you do use your belt then go to a different system do you shallow grind your angles on the belt or steep grind them?

Any tip's or idea's would really help.

Anyway here's my very first 2 knifes completed other than final sharpening and some touch up's. I found out i need to use corby bolt's and not loveless so that's why the fastener's look like crap.

I grind the edge bevels using the slack belt on the grinder (free hand) - then go to stones to knock the burr off & do the final honing.

If you're worried about needing to practice some first to get the feel for it on the belt - just offer to sharpen you friends knives for free:D
 
I grind my edge by rotating my platen so that it is 20 degrees off of vertical. I use a protractor head which contains a level . . . from a combination square set.

This way I can concentrate on holding the blade upright, while setting the edge angle.

Once I get down to a sharp edge, I'll move to the slack belt for the finishing touch.

Same here. Free hand. Good advice on the practice Bruce.:D


It takes some practice to get the edge consistent. Learning how to move your wrist and elbow are just as important (maybe more?) than the angle.

When you get into the belly area, you really need to know how to move your wrist and elbow with the stroke to keep everything even. It's really difficult to explain with type. A video or having someone show you is a good way.
