This morning I put the cutting edge on the second blade. As I said before, the second blade has a different geometry, as I used the stones to put a bevel on both sides of the blade. My plan is to give the guy a chance to use both and let him tell me which works best for his uses.
I went into the kitchen today to do a slicing test on a carrot. Both went through either end of the carrot like butter at all points along the blade, so I was pleased with that. However, I noticed that when I used the tip of the bog oak blade the whole blade tended to flex (like a spring), which occasionally caused the cut to curve out at the bottom if I put any pressure at all into the cut.
In any case, I'll give them a more thorough test tonight when I am preparing the ingredients that go on our pizza (mushrooms, tomatoes, onions, bell peppers) so I can see how well they function over a larger range of textures.
