I really wanted to give this product a 5 star review but I have one major issue with the knife block. I purchased a set of 8 stainless steel zwilling steak knives to complete my block. I was able to insert 7 of the knives with some difficulty but was able to get them all the way in the slot but the last knife I could not get to insert all the way in the slot no matter which angle I used to insert the knife. 
Besides that the knives work like a dream and I really enjoy using them. The self sharpening really takes a lot of the maintenance out of keep nice knives in great condition. [This review was collected as part of a promotion.]
