How fast

Most emails are answered the same working day, and everything inside two. Messages that arrive over a weekend get picked up Monday morning.

Make it quick for both of us

If you are writing about an order that already exists, put the order number in the first line. For anything that arrived damaged, attach photographs straight away rather than waiting for us to ask.

What we can help with

Where your parcel is. Starting a return or refund. Whether the sharpener suits a particular knife. Looking after the wheel and the block over time. Anything that arrived broken or incorrect.
