Chiselgrindquestion

[Ansoknives]

Im working with flatgrinding only at the moment and i was thinkink about the chiselgrind. Would there be any point in making a chiselgrind and using flatgrinding insted of hollowgrinding. The only reason i can think of is that it might look cool and its easyer than dobbelgrinding. I dont know much about the chiselgrind but as i understand it it gives i thin yet strong edge when done with hollowgrinding. I allso heard that the main reason for this in the old days was that there was welded a thin piece of steel to the side of a thicker ironpiece to save the expensive steel.

Jens: I have made many chisel ground knives, and I will offer the following from my experience. First, a true chisel grind does not have a secondary bevel (edge bevel). You can make them with a secondary bevel, if you wish. It simplifies the grinding greatly, bevause the edge doesn't require the precise thickness control of the full chisel grind. With the edge bevel, you can compensate for an uneven grind with the edge bevel. Hope this makes sense to you. I believe that most of the hollow ground chisel blades are done this way, in order to have at least some strength to the blade. I would disagree that a hollow ground chisel knife is atronger than a flat chisel ground blade, though-there is more material removed as a result of the hollow grind, hence, a weaker blade.

Eventually, you may want to do a full, flat chisel grind. It is very rewarding when you can finally make the edge thickness go to "zero" evenly down the entire edge, without affecting the profile of the blade.

I finish my edges with a slight "roll" to them. this makes them quite strong, and they cut very well.

Good Luck

Thanks R.J
I will give it a try soon. And yes it makes sense to me.
