Joseph Joseph® LockBlock 6 Knife Set 4 "No instructions of how to clean or care for knives" Sharon 02 March 2016 Bought these from a Lakeland store, very pleased so far with knife block, but no instructions in or on box, how to clean knives. I would assume the block is just wipe clean, not sure about the knives if they can be put in the dishwasher or just hand wash would be nice to know, also checked Lakeland online but does not say. Lakeland emailed me the instruction booklet, although I may not have bought them if it said on the box NOT DISHWASHER SAFE, HANDWASH ONLY. A note from the team Thank you for placing your review. We're pleased we could help and thank you for your feedback. If products are dishwasher safe we'll display the 'D'symbol on product information.
