I finally figured out why I could sharpen my old stainless knife and why it would dull so quickly after I had sharpened it. It took purchasing a new knife and having the same thing happen to it. I won't be returning the new knife because it helped to teach me what I was doing wrong.
Any guesses on why both knives would dull so quickly and would not hold their edge?
Cutting bricks with them ?
You were trying for the shallow angle of a razor blade? jsw
Had nothing to do with the edge I was putting on the knife when I sharpened it.
*********Is the sheath made out of 600 grit polishing material?
Seriously...I heard on tv that storing knives and razor blades in baby oil keeps them sharp. Also... I did an experiment in grade school, it was a pyramid experiment for a science fair. I stuck dull razor blades in pyramids and they sharpened up. the ones in boxes did not.
Or maybe your dullness is rubbing off?
Neither knife has a sheath.
((((stab yourself with the dullest one)
You did not sharpen them correctly.
Dan
did you "sharpen" with one of those blade manglers where you drag the blade across some hunks of steel and ceramic?
Dan
I figured you had sharpened them so they had a feather edge. Never crossed my mind that glass cutting boards were available. Looks like Precission Machinist had the right answer when he said cutting bricks.

jon_banquer fired this volley in news:ab3dfc6c- snipped-for-privacy@f5g2000yqp.googlegroups.com:
Well, knives are (usually) metal, and this is (supposed to be) a metalworking group. So we should have been interested.
Besides that, for whatever strange reason, even a lot of perfectly competent machinists never learned the 'magic' surrounding knives.
(doesn't make sense, but what is, is...)

Or they are of less than sturdy alloys
