Folks,
When you thin the knife, do you lay the knife flat on the stone and apply pressure with your fingers over the secondary bevel (targeted area to thin).

OR..do you raise the spine just a hair and then grind/thin?

My problem with the first method, i.e. just laying the blade directly on the stone is that I'm going to scratch the face of the blade significantly, i.e. in areas above the secondary bevel as the blade comes in contact with the stones.

I've done this on my own knives, the thinning process itself is very effective, but I wouldn't do this to a customers knife, so I raise the spine just a tad to thin and the a tad further to sharpen it.

Hey..why don't I tape the knife to prevent scratching, is this the secret?

I'm an idiot

Depends on the knife Peter....but typically I raise the spine some aiming for that shoulder ridge.

Second that. I raise the spine off the deck just enough to clear the secondary and maintain light but targeted pressure on the bevel shoulder and progress up and down the blade. Works very efficiently for me on everything from kitchen knives, folders, camp, etc. Allows thinning without scuffing up the secondary.

You guys, always taking the easy way out ;)

But...... in most circumstances, its probably enough to raise the spine slightly, but if you are sharpening the knife a lot, either because you use it so much you need to, or because you have to get your stone fix in, you get to a point much like the primary edge getting to obtuse, the secondary will get to obtuse as well.

Ought heck, why am I telling experts what to do..... I just going to go off and grind something :twisted:
