Just gifted this set after much online research.  Love the curved bolster which feels so good because it doesn't rub up against my finger when holding.  The curved shape blade helps me work on my rocking motion, but also works with the tradition Japanese chopping technique which uses the back of the knife without out interference from the bolster.  The full tang gives the knife enough weight to help the knife do some of the work.
I love the look of the acacia block, which has extra slots for additional knives, and houses the uniquely styled curved blades.  The lifetime guarantee sweetened the pot, and definitely closed the deal.  Glad I chose this block.
