Hello, I have just recently purchased a 7.75In Kasumi Titanium chef knife and a 3in paring knife. I haven't seen to much information on these knives so now im beginning to have doubts.I haven't received the blades yet but they will be shipped soon. Im wondering if i should just cancel the order and get different blades or stick with the Kasumi. Are these good knives to own? What are the advantages? What are the disadvantages? Will they stand the test of time? Are they easy or difficult in maintenance? Any information of these blades would be helpful and well appreciated, Thank You.
