This Calphalon knife set seems to be a great set.  I like the stainless steel look-it coordinates with all the new kitchen appliances.  The knives all work as intended and are very sharp.  Since I just started using them, I am assuming they will stay sharp with the built in sharpeners in each slot.  I wish they had some instructions in regard to the self sharpening slots.  I am not so sure they will stay sharp just by rubbing against these sharpeners while taking in or out of block-or if you are supposed to put some pressure on them while removing and inserting knives.
